Number crunching :
What if... All future WU's were VLAR ?
(Message 1014224)
Posted 10 Jul 2010 by  JDWhale
Post: From the replies I see here, it seems that the BOINC Manager Preference not to "Use GPU while computer is in use" option is either being ignored by users, or not implemented very well by the application, if at all. Not being a "GPU cruncher" myself, I can't feel the pain by those of you that are. But my experience programming parallel computing devices dating back 25 years (past tense called 'array processors') might lead me to believe that some lessons learned long ago are possibly ignored with the current implementation [possibly at the driver level?]. |

Why did they limit dl's at all?
(Message 1014187)
Posted 10 Jul 2010 by JDWhale
Post: Not everyone is getting downloads as needed.. and people have not yet been able to stock up for next one... so ALMOST brilliant. Plenty of time to 'stock up' as seen last Monday... Apriori is being able to upload and report results after the outage. In the past this might take 24+ hours, now it's almost instantaneous with new work distributed to the hosts that need it most. Without upload/reporting new downloads were impossible... Not anymore. BRILLIANT !!! (Agreed, some fine tuning is desirable... but it's still much, much better than after prior outages.) Did I say BRILLIANT ? |

(Message 1014156)
Posted 10 Jul 2010 by JDWhale
Post: Please excuse if this topic has already been argued, but here goes... I've got a problem with all the moaning about folks not being able to feed their GPUs at maximum efficiency... complaining the the required AR's for max RAC are not being supplied by the download feeders upon request. Not too long ago, in the CPU only crunching era, this was considered "cherry picking"... The act of cancelling or otherwise thwarting poorer paying WU's to maximize your RAC... your perceived throughput. In the past some crunchers might have realized that different cache sizes or CPU architectures yielded varying performance on different Angle Ranges and might have cancelled poorly rewarding WUs based on this knowledge (or other 'cherry picking' reasons), while the 'pure' cruncher crunched whatever he was fed... even if it tasted/paid like sh*t. How is reschedueling poorer performing WU's from GPU to CPU any different, especially when you might end up with months worth of work queued for the CPU while your GPU sits idle waiting for the cherries to show up? If you are as committed to crunching for the project as many of you say you are, and have spent the cash to build super crunching machines that exclude poorly paying (credit wise) WUs... What would you do if all future WU's were VLAR? Which just might happen as interesting targets are identified and the search narrows to specific points in the sky (I don't know if this is true, just hypothesising :) ? Just a thought... Warm regards, |

This computer has reached a limit on tasks in progress??
(Message 1011145)
Posted 3 Jul 2010 by JDWhale
Post: AFAIK, this project has never asked for more than "spare" CPU cycles to get the job done. If this has changed, please let me know. Building more and more powerful systems then complaining when work is not available to feed them seems against the original concept of the project. It's my opinion that we should be happy when the admimistrators of the project allow us to crunch for them. Isn't that why we all originally joined the project. That was the way it was when I joined back in 1999 :) |

Posted 2 Jul 2010 by JDWhale
Post: This is brilliant! But if the downloads/outstanding WUs are limited to 20 tasks per host after the outage, the download pipe won't stay clogged for 24+ hours, thus blocking uploads as in the past. Bottom line... my host has work shortly after the servers came back online. In the past it might take a full day before my results could be fully uploaded and requests for new work issued. Again... This is brilliant!!! |

Posted 2 Jul 2010 by JDWhale
Post: This is brilliant! Normally after a significant outage I can't upload my results and therefore can't download any new tasks. However this time that's not the case. Uploads were no problem after the outage and a few new tasks (number is 20) were downloaded to the hosts that had run dry. I can hope that this is the intended behavior and more WUs will flow freely as the network/server traffic after the outage eases. |

Can Seti run off a ram disk?
(Message 999488)
Posted 29 May 2010 by JDWhale
Post: I've run BoincPE on diskless systems that boot from a 512mB USB flash chip... The chip can be marked as read only and copys the disk image to RAM at boot/system startup. Persistance can be configured to a networked server at scheduled intervals. Remote access is pretty easy to setup using TightVNC. It's been a couple years since I set up the diskless systems and am no longer running them for various reasons. IIRC, the most difficult part was getting the network interface controller (NIC) drivers installed for the different motherboards. It isn't easy to use the various tools required to generate the final disk image on the flash drive, but if you've got enough spare time to research and do the necessary trials, it can be a gratifying experience. Good luck, |

Post: One problem using Idarionis "Visitor" mode is that some types of sites, like "Dragon Cave" or "Valenth", might require an extra action to credit the subscriber. I've found that using "snap links" add-on (different version depending on FF version) in addition to "flash-blocker" with FireFox allows me to cruise through the Idarionis links faster and perform the extra action faster than using "Visitor" mode and lets me perform extra action necessary to credit those "other" type sites. (right mouse button-drag opens all links inside dashed green box in separate tabs simultaneously... very, very fast! Use <ctrl-w> to close tabs after visiting). Additionally, this method allows you visit only those cities you wish to visit quickly and to leave messages at your favorite cities. "Auto-visit" requires you to make extra visits, which aren't counted, to leave messages. Also, it doesn't help any to have more than one user listing your site... Each mini-city is only allowed one visit per day per IP address... any more than one user listing your site just wastes clicks. This is why I don't show up on many "history logs"... I've already visited the minicity and don't want to "waste" another visit via Idarionis. Happy clicking, JDWhale |

Post: A random sample of the examples given show the wingpeople reported different dates/times and all before the 15th. So if you're a wingperson to one of these it would be difficult to spot. Correct... if the wingman reported after I did, then the WU validated without incident was removed after 24 hours. It seems that the servers hiccup'd when I reported these results causing backend events to be lost. |

Post: I think the lesson here is... go ahead and mount the HSF with "stock" push-pin mounts... take care and be sure you feel/hear the click on opposite corners. Grab the HS and wiggle it around to see if the push-pins release. If not then you have a secure mount, If some corners release, then you must try again. Follow Jokers Xigmatek HDT-S1283 or Kingwin RVT-12025 cpu cooler Tutorial for yer crunchers thread... use needle nose pliers on rubbers to remove/install the fan to the heatsink.. else you will skin your knuckles when applying proper pressure to push-pins. (You being a 'fine' young woman will not have the same problems I had with my 'fat' old knuckles :)) In my case, it was 3 trys before the push-pins passed the 'wiggle' test and I had a secure mount. The problem had to do with not applying enough pressure on diagonal corners when mounting the HSF. This is not an easy HSF to mount...use Intels instructions of applying pressure to diagonal pins and 'locking' them in before applying pressure to adjacent corners and you should be okay. If you still can't get the HS to 'lock' down... then get yourself a mounting kit. Gluck, JDWhale |

Post: I have noticed in my virtual window shopping that there are dedicated chipset coolers as well. But I don't think that I need to go that far just yet. :) Looking at this review of ASUS Silent Knight II I'd rather stick to something with better cooling properties... I've got both the ThermalRight Ultra Extreme 120 (TRUE) and the Kingwin RVT-12025 (Xigmatek HDT-S1283 equivalent) and can recommend both as having similar cooling capabilities. (Both are mounted on same Gigabyte MB & Q6600 systems) The Kingwin, IMO, wins hands down at half price with fan included, if you can still find one. Mount the HSF so the heatpipes are perpendicular to the bead of AS5 for best cooling and the fan will blow across the northbridge HS and you will not need a northbridge fan at all. Don't get caught up with all the LEDs... choose performance parts over show parts for a cruncher... If you want to stay at stock speed the ASUS HSF is fine and IMO is aimed at teens for show... but it will not help much making Q-Baby go. Regards, JDWhale |

Post: I am going to let her run ’as is’ for another 2 to 3 weeks but, before tweaking things, I guess I had better think about upgrading the stock cooler first. I'm really happy with KingWin RVT-12025 HSF (about $30 US including fan) Orient so the heatpipes cross the line of CPU cores. A bit difficult to install, but Joker posted a fine tutorial a few months back. (might have referred to XigmaTek equivalent HSF, but they're seemingly identical) You might consider purchasing a mounting backplate, but the pushpin mount works fine for me. Q6600 @ 3.0 Ghz on Gigabyte GA-P35-DS3L Ambient 30C CoreTemp 60-56-52-58C running S@H AK_V8 on 4 cores 24/7 (RAC > 5200, MB only, NO Astropulse) A word of warning...it might take a few practice mounts before you 'get it right'... refering to amount of AS5 and uniform spread/pressure. Yes, the northbridge HS gets hot, but with good airflow through the case I've not had any problems. Good luck... |

Post: If all the bits haven’t arrived by the Sunday (my next day off of work) I’ll likely break down and do some assembly. :) keepin' my fingers crossed... just remember... a thin bead of AS5 inline with the CPU cores... thinner is better with a slight back & forth motion of the HSF to smear the AS5 a little. that AS5 really spreads out when you push down on the HSF mounting pins. Use 90+% isopropyl alcohol and a coffee filter to remove the factory gloop from the stock HSF and to prepare both HSF & CPU surfaces prior to mounting. g'luck, |

Post: Just notice this thread and saw one point missing. Dual channel is the way to go, but also consider that you are installing a quad. That is 4 cores that are all going to need to use the ram. S@H seems to work best if each core has 512K. So I strongly suggest 2 1 gig sticks. As for brand, I like corsair. But basically get the fastest you can afford, it's all pretty cheap these days. A suggestion re mail in rebate... wait until your system has been up and running ~2 weeks before sending in rebate just in case your memory fails early. The stores usually will not exchange once you've cut the UPC from the product forcing you to deal with the manufacturer directly for an exchange thru the mail. Also agree with Mark on hard drive...

Yep, you need 2 matched sticks to run 'Dual Channel' which allows twice memory bandwith. Will definitely show improved performance when crunching 4 VHAR 'shorty' WUs. Also.. memory prices & rebates vary day-to-day... keep your eyes on the local discount store ads and pounce when you can get a 2 x 1GB kit for ~$40 after rebate. Also look for PC2-6400 DDR2-800 for best bang for the buck...example deal G.SKILL 2GB (2 x 1GB) |

Post: Am thinking of 1gB of Patriot memory for now. (about $50). Will add another gB later if needed. I'd suggest buying a "Dual Channel Memory Kit" either 1GB (2 x 512MB) or 2GB (2 x 1GB) for better performance. If you only buy 1 memory stick now, then add another memory stick later, your computer might not (probably will not) operate in "Dual Channel" mode. Look for 2 memory sticks in a kit. Thermakatite cooler. ($40. A good deal?) IMO, you do not need to buy an aftermarket cooler until you decide to OC your CPU. The stock cooler works just fine for running at stock speed... assuming that you are buying a 'retail' CPU that includes the stock heatsink/fan(HSF). OTOH, some aftermarket HSF require you to remove the the motherboard for installation of a mounting plate on the backside of the motherboard. If that's the case then it does make sense to use the aftermarker HSF on first install to save you from later grief. Measure your case to make sure you have clearance for any aftermarket HSF. Also, I have tools (screwdrivers, needle-nose pliers, cutting torch, sledge hammer, and can curse in 3 languages so I have that bit covered!) :) The more hammers the better... And I bet you cuss like a sailor...LOL :D gluck, |

Post: One problem that I've had trying to reuse a Dell case for a new build is that the backplate (where MB USB, E-net, sound, etc connections) was proprietary and was only usable with the Dell motherboard & MB tray. My advise here is to verify that the backplate on your HP case is removable and will allow you to fit a different motherboards backplate. It is easy to assume that since you have a case that any ATX MB will fit, but it's been my experience that most the time it's more work than it's worth when working with a proprietary case. Building your first computer from 'off the shelf' parts is a thrilling experience, I just hate to see the frustration when the case doesn't fit your new motherboard quite right. Just be sure to leave enough $ in your budget to buy a new case if necessary. Maybe take the case you already have with you to the shop when you buy parts and ask them if what you plan will work. Good luck, JDWhale |

Post: Can you post a picture of the inside of your case, the MB mounting area? It will allow us to see if it is ATX or micro-ATX form factor... Then we can advise compatible motherboard. |

Post: Check the case you are using will fit an ATX motherboard... since in the future you'll want to OC some and all the best OCing MBs are ATX form factor. I recommend the GIGABYTE GA-EP35-DS3L MB paired w/ Q6600 CPU & cheap Kingston 2x1GB memory sticks @ PC6400 add any hard drive & compatible graphics card. You do not need anything more than a minimal graphics card. Stock CPU cooler is fine until you decide to OC, then switch to Kingwin or Xigmatek. Important step in assembly is not to apply too much thermal grease between CPU & heatsink. Good Luck, JDWhale |

Post: I was extremely lucky... only dropped power for 18 hours... very minimal damage. Driving the nearby neighborhoods there are lots of folks without electricity, lots of trees down and some roof damage. Fortunately we didn't get a lot of rain in my area with the storm, just 80 MPH winds. Hundreds of electric utility crews from more than 30 states and Canada are in the Houston area working 16 hour shifts to restore power. Galveston has been proclaimed non-habitable by the Texas Health Comission because of lack of electricity, water and sewer services. Boliver Peninsula to Galveston Island northeast was the hardest hit... I fear it will be months before public services are restored there. Supermarkets in my area are open, limited hours, and gas stations have gasoline. I heard last night on the local news that 50 of 52 Home Depot stores in the greater Houston area have reopened. Best wishes to those less fortunate, JDWhale [edit]Here's Weather Underground link to a station the center of IKE passed over. Note the minimum Barometric Pressure and calm winds at 3:43AM, 13Sep and the 180 degree shift in wind direction. This station is not too far from Geek@Play home. [/edit] |

Post: Sad story on the news today... a woman had just purchased a gasoline powered generator.. still in the back of her pickup truck... waited in line 4 hours to buy gasoline and the station ran out of gas as she neared the pumps. She has the geny... but she ain't got gas. On the upside... a cool front passed through the area 2 days ago... overnight temps are dropping below 70F... about 10 degrees lower than normal this time of year. Daily high temps are running low to mid 80s... about 8-10 degrees lower than normal. I got out today and drove a bit larger loop... still a lot of folks without electricity. Gas stations that have electricity the lines are getting shorter, but the gas stations without electricity can not pump gas. Those stations with gas are selling regular 2 week quantity within 12 hours. Here's a link to KPRC Houston NBC-TV affiliate with some interesting information & videos... check out our senior weatherman, Frank Billingsley' Walking Tour of Historic Galveston. He has a home in Galveston that was flooded with 3 ft of water. Best wishes for all, JDWhale |

Post: Winning after a terrible storm. It was enough to be considered Hurricane strength at times! Galveston, Texas reported 104MPH winds.... we had 84MPH winds..... not too far off! Just got electric back after a day and a half without it. Most of Ohio, Kentucky, and Indiana are still without power though. Last night when it hit 99% of the state of Ohio and ALL of Northern Kentucky was pitch black..... kinda creepy. Down here in Houston area, we're still not getting any national news... the local news pictures are horrific enough now that the local news helicopters are allowed to fly again. The news reports in Houston are that the most devasted areas are on Bolivar Peninsula and High Island. Yes, Galveston Island will not be habitable for the next 6+ weeks, but the areas to Galveston northeast (Bolivar & High Island) were hit even harder by storm surge and higher winds :-( BTW: I'm winning. |

Post: A cyclone is a unique type of storm. Having lived on the Texas Gulf coast for more than 30 years I have become somewhat experienced with the characteristics of these horrific storms in my area. The difference of being located 35 miles either side of the center path of the eye of the storm is like the difference between night and day. I live 35 miles southwest of the closest approach of Hurricane IKE' center and am located on the 'clean' side of the storm, we are only having minor inconveniences. Folks located nearer the center and up to 100 miles to the northeast of the path are suffering very much, still being without running water, no electricity and roads that are not passable. Some services are expected to take 2-6 weeks to restore... The surviving residents of Galveston Island and Bolivar Peninsula have been asked to leave their residences and not to return until infractructure can be restored... maybe upto 2 months from now. My heart goes out to the residents that live just 50 miles east and northeast from me... I wish all of them the best. National news is still unavailable over broadcast media, we have enough local news to keep all network broadcasts busy... 24 hours/day! Local news right now is reporting that electricity has been restored to 550,000 customers, yet 1.5 million customers are still without electricity. Those of us that live outside the most devastated areas have been requested to stay home and share our resources with our nearby neighbors that are less fortunate than ourselves. Lots of BarBQs in the neighborhoods with folks meeting some neighbors for the first time. Best Regards to all, JDWhale Postscript : I understand Matt Lauer from NBC 'Today Show' was in the Houston area this morning... Unfortunately those of us in Houston did not get to see the show because it was pre-empted by local news :-( I really would to like to see what news is getting out of our area to the rest of the country. This just in... : Local news reports... Hundreds and hundreds of ultility velicles (electricity and tree choppers) are making way to dispatch area (horse race track in northwest Houston). These vehicles are from 25 states and Canada. Thanks for the help folks !!! Also a family rescue of 6 people feared dead on Bolivar Peninsula. Praise God! |

Post: Aren't there still a few million people without power over there (and no, I am not expecting to hear from any of those people for a while). Haven't heard any figures about electricity today... Last numbers I have were from last night 112,000 customers in lesser damaged areas have been restored, more than 2 million customers still without... One problem is that there is no point even attempting to restore electricity to areas that are flooded. You folks outside the Houston area have probably seen more of the damage than us locals have. Without national news all we're seeing is the local newscasters/reporters... local news choppers are restricted from flying because of the national guard and federal disaster relief. One local news report is that the death toll is being intentionally underreported until next of kin can be notified. People staying behind in mandatory evacuation areas were asked to write SSN on their palms so they could be identified later. Sad, but true. |

Post: Thanks for the wishes... Eye of the storm is still ~11 hours from landfall...With the adjustments in predicted path over the past 24 hours, I have moved from a direct hit with the eye crossing over the city of Sugar Land, TX... Now the eye of the storm is predicted to pass 35 miles to my northeast. If you look at a map the current expected path follows Interstate 45 up from Galveston, TX toward Dallas. This places me on the "clean" side of the storm with winds mostly coming from the north, then from the west as the eye of the storm passes nearby. Much better position to be in than if the storm track were to my southwest, putting me on the "dirty" side of the storm, where spawned tornados are expected to occur. Though the gun hasn't actually been fired, I am feeling that I have already dodged the bullet... I might feel different in 12-24 hours. Our friend Geek@Play lives in the direct path and much closer to the coast... I hope he has already evacuated. Later, JDWhale |

Post: Had do pick my son from the airport this evening... The evacuation from Galveston Island went very smoothly earlier today, by this evening there was only light traffic along the evacuation route. The weather reports are looking a bit more favorable for me... Latest models show the eye of the storm path having moved from where I live to about 30 miles to my northeast... straight through downtown Houston. With possible 20 ft storm surge up the Houston ship channel. Also known as "refinery row". Should have a much better idea on path in 8-10 hours. Cheers, JDWhale |

(Message 806787)
Posted 10 Sep 2008 by JDWhale
Post: JDWhale, Sorry to hear of your recent losses :-( As you probably know, performance depends on a few factors... Your "Dads" box has higher BOINC benchmarks than Marks Frozen Penny(QX9650), but he recently switched over to DDR3 RAM and he is running at a higher freqency. Additionally, he's not getting the benefit from crunching all the VHAR WUs that you are. Hard to get an apples-to-apples comparison... One thing remains certain, when it comes to bang-for-the-buck it still seems single quad-core boxes rule... Too much overhead and contention for bandwith when running more than 4 cores, IMO.

you'll be waiting for work

(Message 806761)
Posted 10 Sep 2008 by JDWhale
Post:
Doing the math on a few of the WUs you've returned... You are crunching VHAR WUs in ~9 minutes. If you were only to crunch these you could complete 600+ WUs/day. Figuring that you will receive a mix of Angle Ranges from the project and the speed that you are crunching the MidAR WUs (~0.44 AR), ~32 minutes each, it is conceivable that you will crunch more than the 400WU/day download limit for your CPU on some days. This is mainly due to the proliferation of the shorties (VHARs) currently being distributed. Expect your cache to build slowly if at all. I figure your new host might make the top 10 hosts with RAC > 8000 if the project can keep feeding you enough work. Nice box you've built. Regards, JDWhale |

Do not believe the 'remaining time' shown.. calculate the 'true remaining time' yourself from the %complete and elapsed CPU time. This will miss deadline and be reissued with the possibility that you will not receive any credit. Your PIII should not have received any AP WUs because your host cannot complete before deadline!!! |

Post: Meanwhile, we're out of space again on the workunit server, and with no fast/easy way to add space. Eric's playing with the splitter mix to reduce the number of Astropulse workunits being generated (they are much larger than SETI@home workunits). Maybe that will help, but not immediately. This is what's mostly causing our headaches today as we can't create enough work to keep up with demand. Maybe if Astropulse paid more, there'd be more demand for its WUs... I'm about to finish up an AP WU sent to me 3 weeks ago, but it's worth less when it was issued to me than now... This will not thrill my new wingman who is claiming more credit than me. In the economy this is call deflation :-( WUs should be worth more over time rather than less... There is no investment value if the claim doesn't increase over time with new wingmen! How can the same WU be worth more credit just because it had to be reissued? Maybe all users should cancel their AP WUs so the WUs will increase in value! |

Maybe that does explain the extra reduction... on my hosts the "shorties" pay the best RAC. Killing them only hurts your RAC more. It's the old 63.98 credit WUs now earning ~52 credit that were recently distributed in excess and caused increased drop in my RAC. Anyway, whatever your reasons... we're sorry to see you go.

There has been a significant number of VLAR WUs (AR 0.008-0.010) recently. The 'pay' for crunching these is much less than Mid AR WUs. This might attribute to the recent increased loss of RAC on some model CPUs running AK V8. I've noticed it on my Intel Core2 based hosts. |

Post: I was really thrilled when Seti started, imagine looking for life outside of Earth. Me, too... When I started running SETI 'Classic' back in 1999, I knew there would not be results in my lifetime, that this was a 'long term' commitment. I am happy that the client is faster now and we are nearly able to keep pace with the gathering of data, but more optimizations will be required in order to crunch increasing data streams. I do not have interest in computing for other projects or in what credit they might claim. It they choose to keep their source code to themselves, how can they have the fastest clients? Maybe they do not have the amount of data to crunch as SETI... Maybe they do not require optimized clients. |

How to develop an optimized application?
(Message 800293)
Posted 21 Aug 2008 by JDWhale
Post: Hi! Q. How do I develop an optimized application? A. Look at the original code and find a better way to code the algorithms (or start with the already optimized client from lunatics). Q. Are there free compilers? A. Yes... Intel offers 30-day evaluation of latest compilers... Just visit intel.com. But you will also require Microsoft Visual Studio(also free with 90-day evaluation) and a working knowledge of how to use it. Also, fetch an evaluation copy of Intel Performance Primitives (IPP) to use optimized FFT, Convolution, and Transpose functions. Q. How should one test optimized application? A. Download/run 'KnaBench' from lunatics Q: Where to get a test workunit? A. Included with 'KnaBench'. Gluck, JDWhale |

I ain't at Berkeley, but can duplicate your 'anomaly' simply by renaming the '..\BOINC\statistics_setiathome.berkeley.edu.xml' file and restarting BOINC. The date/time of 01 Jan 1970 is t-zero for system clocks... system time is kept as seconds since 01 Jan 1970. Since the 'stats' file is missing, there is no valid data to populate the graph with, so it centers around some default/initialization value... t-zero and zero credits. As soon an your host performs an 'update', the statistics data is DL from the project and the 'stats' file is created with valid data and the 'anomaly' goes away. Keep on BOINCin' JDWhale Added:

Post: First WU completed on the V8 client for SSE(P3) WOW... ~23% improvement in CPU time at one of the worst performing ARs (1.08) We were pretty sure that the new client was faster than the prior optimized clients on the P3... but test data was few and with sparse ARs. IIRC the Mid-ARs (0.35-0.45) showed the best improvements. VLAR and VHAR improvements were minimal if any. Since most WUs are in the Mid-ARs, there should be overall improvement. I'll be keeping an eye on this hosts returned work over the next week or so for comparisons. Thanks, JDWhale |

Post: I only have a PIII - so I tried out the SSE optimization for Windows. Doesn't seem to have made a huge difference (like 10% max). I have read other posts that claim SSE3 or higher really make a difference. See the sticky thread "AK V8 ported release ap. issues, install, questions etc." for more details. Which "SSE" optimized clients have you tried ? I see from your history that you have a result from "R-2.4V"... Have you also tried Windows 32 bit AK v8.0 SSE (Pentium 3)? I'd be interrested in seeing some comparisons of CPU times on WUs with similar Angle Range (AR) of both clients. Regards, JDWhale |

You might consider putting the AP WU in suspended state and then resume if/when the servers run out of work.... Just a thought. Happy BOINCing, JDWhale |

Congratulations... You deserve a pat on the back for persevering, thanks for posting and allowing us to share your experience. I hope you don't mind that I point to your AP WU, wuid=309347223. The best thing about AP WUs seems to be that extended runtimes might fill in gaps of lean WU splitting and server outages. On the otherside... some might say that the lack of work is being caused by AP WU splitting and distribution. Comparing CPU times and credit claims of MB and AP WUs on your host, it looks like AP is underclaiming MB stock client by ~40%. As this is supposed to be addressed with the "adjustable" sliding multiplier within 30 days to narrow the gap, it seems that the early adopters are paying a premium to be the "guinea pigs". This is just the opposite of what I would expect; If the project administrators wanted to gain acceptance it seems they would be paying a premium in credits at first and allow the gap to narrow from the other direction. Folks might then be more accomodating to crunching AP during these "early" days; Especially considering the earlier distribution of "ghosts" and guaranteed missed deadlines due to issuing AP work to underqualified hosts. Just my opinion, JDWhale |

Post: wuid=313778905 Another case of AP begin sent to "underspec" host... in this case 850 MHz PIII. This host received 2 AP WUs on 10 Aug (yesterday). Fortunately the host owner realizes the WUs will not complete before deadline and cancelled them. What happened to the "Minimum CPU: 1.6 GHz" requirement ? IMO, more work to the scheduler is still needed. |

As long is it's 'fish' that you're feeding the kitties and not any whalemeat... I'd hate to have to 'tail slap' you....lol So if I read some prior posts correct... I can revert my app_info.XML file and not be worried about creating any more AP ghosts. Just for safety sake, I'll leave the file 'as is' and just cancel any AP work assigned. Except for the ones that have been reissued after validation... I'll wait to cancel them after a resolution is posted on that issue. I do hope someone is working on that particular issue... validating an AP WU, granted 0 credits, then issuing a redundant instance of the WU just to waste 30+ hours of CPU cycles. Afterthought: Also refrain from crunching AP WUs until the issuing of work to hosts that are guaranteed not to complete within deadline... like the 500-600 mhz PIII and Celerons. Please forgive me if this issue has already been fixed, I have read nothing addressing a resolution. |

Post: It should not download the work if you do not have the files in place for it though.

If I read the above statement a slightly different way... "If you are using an optimized application, then you need to replace or modify the app_info.xml file, you will get AP WUs". @Arkayn : Thanks, I've already modified my app_info.xml files, but the damage has been done with the first AP WU. @UL1 : I saw your earlier message about receiving one of the AP WUs on your MAC, I saw the same messages in my Win Vista log file. [edit] @msattler : Here's one of your AP WUs... Have you changed your app_info.xml to understand how to crunch ?

I was waiting for the official "An app_info.xml file will be made available here" section of the Astropulse FAQ to be created. Seems this didn't stop the project from issuing an AP WU to my host, which was immediately dismissed due to missing AP client, causing my issued WU to become a ghost. It will "timeout" on 02 Sep and then be reissued.... Sorry wingman. I doubt that I'm alone, and unless folks pay close attention to their message logs and "Computer Tasks" webpage, you won't even notice you own ghost WUs. Question is... How many others like mine are there ? Be warned folks, unless you want to be a Ghost Rider, do not postpone updating that app_info.xml file ASAP. BOINC on..on... JDWhale |

Post: no credits are forthcoming. The last credit I received was on July 23. My account shows that all the credits are pending. It has never taken 4 days to get a return and I joined this hunt on May 18-1999. A quick look at your hostid=3732303&offset=20 shows credit is being granted... I understand some "stats" sights like boincstats are not updating due to changes in data exchange format a few days ago. You might also be suffering from Macs not being able to fetch new work when the project support folks are running new scheduler as discussed in this thread among other places. |

New Credit Adjustment?
(Message 787789)
Posted 27 Jul 2008 by JDWhale
Post: ISn't that were the task duration correction factor comes in? The duration correction factor (DCF) is used to calculate estimated CPU times to run WUs and to calculate the amount of work to request from project servers. No effect on credit claim/granting. The difference you noticed between credit claims between your host and your wingman is due to Berkeley changing scheduler programs on the project servers. Last night (Berkeley time) they ran a different version/different parameters... then this morning they switched back to the old scheduler/parameters. WUs returned while running the "new" scheduler have lower credit claims. The new scheduler is having issues sending work to some Apple MAC computers, some other "side effects" have also been reported. |

Post: Only ran one WU on the comp that was consistantly lower. This time my comp had the higher return as compared to my wingman. Think those CPU benchmarks have something to do with it. If you're like me and never shut down, or load BOINC at as soon as you boot while other system processes are loading, it can throw off the speed SETI sees your comp crunching at. I guess it can fluctuate. The "credit claim" depends on which version of the "scheduler" Berkeley is running at the time the WUs are returned. They have switched back and forth between schedulers a few times in the past couple days. |

Switching vista to xp
(Message 787669)
Posted 26 Jul 2008 by JDWhale
Post: I have a computer with a dual core that runs Vista. I just got myself a full copy of XP. I want to know how much faster Seti will run with XP. Do not expect Seti to run any faster using XP... a better choice for high performance would be simply switching to Windows 32 bit AK v8.0 SSE3 optimized client to double your RAC. Your PentiumD 2.8 Ghz RAC ~550 My PentiumD 2.8 Ghz RAC ~1350 Even if you decide to abandon Vista and install XP, I still recommend the optimized client above. Good Luck, JDWhale |

Detatched WU Behavior Change ?
(Message 786887)
Posted 25 Jul 2008 by JDWhale
Post: For JD, unless you missed something in the logs, I'd have to say something different happened there. Yes... the "something different" was that Berkeley switched to new scheduler code on Monday, July 21, as Matt states here. Yesterday, July 24, the old behavior was restored for new detatches with the switch back to the old scheduler. What will the behavior be when Berkeley switches back to the repaired scheduler code next week? To accept detatched WUs or not to accept detatched WUs... That is the question. If the project sees fit to detatch WUs and is not going to accept any detatched WUs, then IMO, the project should cancel them on the affected host. Regards, JDWhale |

Detatched WU Behavior Change ?
(Message 786586)
Posted 24 Jul 2008 by JDWhale
Post: Hmmm... I think UL1's detatched WUs occurred before July 2... explaining prior behavior of allowing results reporting after detatch. I witnessed this with my prior auto-detatch on Jun 17 when I was out of town for a week... completed results kept reporting and getting credit when reported before WU validation by wingmen. Looking through recent WUs, I see others hosts detatched with "corrected" time reported in black rather than the deadline time in green. Yes detatched behavior has recently changed. [edit] Matt's post in Tech news puts timeframe on "new" scheduler Monday-Thursday AM. New detatched WUs are behaving as before (until they switch it again). [/edit] |

Post:
Very well... Since the affected host DL'd another 360 WUs after being detatched by the project, I'll wait 'til 12:00 PDT to perform detatch/reattatch on my end. Many of the 360 WUs DL'd are shorties and are preempting the detatched WUs. Thanks for finding/explaining scheduler change, it sure would be nice if the scheduler cancelled the WUs on the host when being detatched though. Regards, JDWhale |

Post: I'm not quite sure if it's a general problem, because amongst others I submitted these 'detached' WUs on 23rd: I see different behavior... Your "detatched" WUs still display deadline in green text... My recently detatched WUs display Time reported in black text. hostid=4369968&offset=1000 The main problem is that the WUs still exist on my host and were being crunched, then being ignored by project servers when completed or cancelled. Also, I see that resends are now enabled again... I just went into my project directory and deleted the detatched WU files, upon restarting BOINC all the detatched WUs were resent :-( Guess I'll have to manually cancel the ~600 WUs in the cache. |

Detatched WU Behavior Change ?
(Message 786419)
Posted 24 Jul 2008 by JDWhale
Post: Power failure early this morning has changed all work in queue' outcome to "Client detatched". I know this triggers a resend to new wingman. In the past (yes this happens occasionally) I continue to crunch the "detatched" WUs for about 24 hours and receive credit when completed and reported before the WU is validated by wingmen. This has changed. I am now not being credited or acknowledged in any way for completing the detatched WUs. I've cancelled some of the detatched WUs and when returned their outcome also remains "Client detatched" rather than showing "Client error" "Aborted by user" as in the past. Seems that the handling of these "Detatched" WUs has changed, possibly with the new scheduler code. Does anyone know a list of changes brought about with the "new" scheduler code? I guess I'll have to cancel all the work in the cache since the results are being ignored by the project. BOINC on, JDWhale |

C & D crossing simultaneously in opposite directions with D carrying the requisite flashlight conforms to all the rules and also lowers cumulative distance (6 vs. 8 bridge lengths). Rules only state that if two people cross at the same time they must go at slower persons pace and the flashlight is used, not that both people are going the same direction. Please, no assumptions.

Post:
I believe there is another contributing factor on the "red line" data... Wasn't there a switch from Q6600 to Q9450 CPU about the same time as the client changed from 2.4V to AK-V8 client? So while the curves might be "independently correct" they should not be used to gauge performance difference between 2.4V and AK-V8 clients on the "same" system. This is a wonderful chart for demonstrating the performance difference between 32-bit & 64-bit AK-V8 client... assuming same CPU speed and memory configuration is being used. Cheers, JDWhale |

Post: So after all the power failures, having to shut the machine down for one thing or another, reboots due to DVD burning etc., BOINC updated to my account this morning around 7 am, and when I arrived home at 5:30 pm, my machine was frozen. Counting the number of completed work units at 14, and my machine completes 4 per hour I'd say it was slightly over 2 hours that the system froze up. I was getting system freezes about a month ago on my Q6600... Yes system freezes, NOT BSOD. Swapped out my "high performance" Ballistix PC2-8500 with old faithfull Kingston ValueRam PC2-6400 and been stable even since. The Ballistix ran for about 2 months before starting to fail... this was the 2nd set of the product that failed for me and seems to be a recurring problem from reading reviews. |

Post: Hi guys, Here's what I see... So counting the bins from the left beginning with bin#1... I see that during the month of May... when the new AK-V8 client was released everyone was happy and RAC was on the rise, AR distribution wasn't a concern. Working through June, the ratio of bin#4:bin#5 rose significantly... bin#4 yields more cr/hr, so RAC continued to rise in June. Enter July... now many more bin#5 than bin#4... bin#5 pays less cr/hr... thus we're seeing a fall from the June highs. RAC decline is to be expected with the current WUs being distributed. JMO...

With a quick look through the available result history on your T7100 I can not find any WUs ending with any errors. I do see some variation of CPU times on "like" WUs (WUs with same Angle Range), but this sometimes happens depending on workload. Honestly, I've never noticed the Progress % decreasing but I admit that I do not pay attention to that number. I sometimes notice "To Completion" time increasing slightly, though. Since this your "work" computer, maybe you should enable the virus scanner and scheduled backups. Good luck, JDWhale |

What a Frozen Penny looks like (56k warning)...
(Message 779980)
Posted 6 Jul 2008 by JDWhale
Post: I found that some concentrated tinkering with the timings on my PC2-8500 Corsair RAM, particularly the "Performance Level" parameter, helped get RAC up to its present 8264 (was 8500 a couple of days ago) on my Q9450. I think the 12M of L2 cache doesn't hurt, either. I think your "tinkering" is paying off... The frozen penny seems to have a distinct advantage on the VLAR (63.98CR) WUs where higher CPU freq performs better, but on the WUs requiring higher bandwith your "tuned" Q does very well at closing the gap. I wonder if this is a prime example of the P5K Deluxe advertised "Super Memspeed" at work ? |

RAC and Alex V8 code
(Message 779067)
Posted 5 Jul 2008 by JDWhale
Post: Total volume of work still drifting down, but the Penny seems to have flattened out. With the current stream of WUs being dominated by 0.4 - 0.45 AR... I'm afraid Penny is right on target according to my estimates. Another 4 or 5 WUs returned compute errors over past 24 hours on that same rig. If that continues, or more 0.6 - 0.9 AR WUs are handed out, you can expect further RAC deterioration. I can also relate with Jason' comment...I sometimes forget to shutdown IE on my laptop only to discover a day or two later that IE has been a resource hog and not sharing any CPU time with S@H. Another behavior I recently noticed... I was having ISP/networking issues a while back (intermittent cable modem connection plays havoc with my switch) that for some reason was causing WU exit/restarts with messages in stdoutae.txt : 25-Jun-2008 03:51:25 [SETI@home] Task 16ap08ac.12776.15205.7.8.214_0 exited with a DLL initialization error. 25-Jun-2008 03:51:25 [SETI@home] If this happens repeatedly you may need to reboot your computer. 25-Jun-2008 03:51:25 [SETI@home] Restarting task 16ap08ac.12776.15205.7.8.214_0 using setiathome_enhanced version 528 25-Jun-2008 03:52:31 [SETI@home] Task 16ap08ac.12776.15205.7.8.214_0 exited with a DLL initialization error. 25-Jun-2008 03:52:31 [SETI@home] If this happens repeatedly you may need to reboot your computer. Well restarting BOINC and rebooting computer had no effect... but disabling network activity restored normal behavior. This same problem was occuring on multiple hosts. Good luck, JDWhale |

The sweetest little 4-core on the block
(Message 778821)
Posted 4 Jul 2008 by JDWhale
Post: It's not a question of "hiding" behind an older host. That is my first host_id on Boinc and, call me an old softie, but I am emotionally attached to it :P And I recognise the numerical ID easily when browsing host lists. This host started as a C2D E6400 on an Asus P5B D/L MoBo running XP Home (32 bit) with PC2-6400 (400MHz) RAM. It has morphed, via a Q6600 brain transplant, to a Q9450 on an Asus P5K D/L MoBo running Vista Home Premium (64 bit) with PC2-8500 (1066MHz) RAM. The only time that I have had a new host_id spawned was on the change of OS. Running down the newly-acquired (very small) cache on the new host_id and then transplanting the Boinc folder from the old installation successfully restored the familiar id (though it errored out on the WU's still in the old cache and downloaded new ones). I understand being sentimental about a hostid, but I think that each new host should sport a unique hostid... not share with prior hosts. Isn't that the point of having a host identifier? If for some reason the project wanted to identify all the work performed by a specific host, but that hostid has been reincarnated as the CPU and/or MB changed, the DB fetches based on hostid would not be accurate and would contain more rows than intended. I'm wondering what happens to the stats associated with a particular CPU type when you change from a C2D to Q6600 to Q9450... Are all the WUs and stats associated with the prior CPUs now polluting the pool of numbers for Q9450 hosts? For example...Does your host contribute to the Q6600 stats on this BoincStats host_cpu_stats page? I don't know... But IMO, it should since it crunched WUs as a Q6600... Don't you think? Just my opinions. The new entrant to the top 20 this morning that I expect to stay around is heinz and his skt (nice one heinz). Yep, this is one to watch... I quickly estimate _heinz host will reach RAC 9250-10,500 depending on WU mix. Cheers, JDWhale |

Post: Sorry didn't know "TRUE" referred to a HSF. A quick review shows my oldest Pending to have reported about 40 days ago. You may well be right in your estimate of when I swapped the processor (and the MoBo - the RAM upgrade came a little later) but comparing crunch times on a range of sample WU's with the other rigs inOkay... why hide behind an older host? Why not start from scratch and eliminate any confusion? My point is... here is another top 20 host... This host was just created in the past 24 hours. How can I believe the RAC that put the host in the top 20 when it was just created? So many ways to confuse the stats... Lets keep it simple and without a doubt. I can't even merge the same host with itself running the same OS... I find it hard to believe the posted hosts in the top 20. [My last OT post in this "AstroPulse" thread...] |

Post: I reckon I've got the sweetest little 4-core on the block ATM. My Q9450 @ 3.56GHz on air with a TRUE has been on the first page of the top-hosts for the last few days. The only other non-Xtreme quaddie up there is an X3360 clocked at 4GHz by "Anonymous" so he's either got a very sweet chip or is chucking lots of Vcore at it and H2O cooling. "TRUE" what? Creation Date of 12 Jun 2007 22:33:49 UTC ? Hmmmm... IIRC, you started up the Q9450 ~65 days ago... so you might still be collecting credits from the prior CPU? I don't have a problem with "plugging in" a new CPU, but you really should do a reset and start from scratch when you do the swap. JMO. |

What a crappy case I have
(Message 778169)
Posted 3 Jul 2008 by JDWhale
Post:
Newegg has excellent photos/descriptions/reviews, do your research. If I can "look" at a case, then I open it up and examine the number of fans and locations, case air filters, hard drive cage and mounting methods, room to work. An example is when using the Heatpipe Direct Touch(HDT) HSF... Are the exhaust & intake fans in the correct location for the orientation of the HSF depending on the type of CPU being used(Dual or Quad)?... Yes it makes a difference. It's summertime in SE Texas and my Home Office maintains an ambient temp of 33C (CPU cores 62-56-56-58C). A case that provides proper/efficient airflow is important. |

RAC and Alex V8 code
(Message 778148)
Posted 3 Jul 2008 by JDWhale
Post: Thanks Looking through your history, I see a few compute errors returned in the past couple days... These are an effective way of decreasing RAC. Also you have been crunching a few VLAR WUs (63.98CR), which consume more CPU/CR than the mid AR WUs. Other than that, 10% swings are not uncommon as the WU distribution changes... at RAC 8700, 10% might bring you down to ~7900, though I think a range from 8000-9200 might be more typical for this host/client combo.

Alright... I made it home and checked my host earlier described... It runs BoincPE with persistence (backs up every 6 hours). The host rebooted (possible power outage... Thunderstorms were in the neighborhood the night it rebooted) and restored BOINC from the last backup. I guess this caused the "forced detatch" as new WUs were DL and results reported between the last backup and the reboot. This causes double reporting and ghost WUs. Anyhow... it would still be nice if the project could/would cancel the detatched WUs. Thanks for all the feedback, JDWhale |

Seems to me that if the project is going to detatch a host, the associated WUs should be cancelled on the host. For the past week Lovey has been crunching WUs and getting credit less and less each day. So much for "set it and forget it". |

Post: I'm not quite clear on WU uploads & downloads, but a website can have more than one registered URL that points to that IP address. Understood. Both of these URLs seem to point to the exact same webpage. If one is "correct" for the project and the other is "wrong"... then the wrong one should point to and load the correct one to avoid confusion, IMO. But then I am only a programmer and am ignorant to details of webpage management... Maybe what I suggest makes no sense to project webmasters. When I went to attach to "SETI Beta" via BOINC Manager, I didn't see the project listed on on the popup selection list. So I performed a google search on seti+astropulse. The first returned result seemed the only reasonable result on the first page and after viewing, seemed especially reasonable. Only after attaching to it and DL ~150 hours of AP 4.33 work I view my "messages" where I was informed that I attached to the "wrong" URL and provided with the "correct" project URL. It's no problem... I'm just making comments about my "attaching to SETI Beta experience"... I'll detatch then reattach to the "correct" URL after my AP queue is empty. |

Post: So... I though I'd checkout what all the hoopla was about and attatched to Beta last night... promptly DL 5 AP WUs. Crunched on one WU for almost 15 hours and reached 44% complete. Now BOINC Mgr says it's running the AP WU, but no more progress or CPU time is being logged. Task Manager only shows the 3 S@H WUs getting CPU time. Also my host has frozen/locked up 5 times in the past 15 hours. I've seen BSOD a few times in the past... maybe 3-4 times a month, but never total freeze/lockup. Coincidence??? I don't think so. I've suspended Beta project and rebooted and resumed S@H on all 4 processes. If stability resumes, I'll abort all Beta WUs in my cache. I could try setting the host to stock/factory clock and try again, but that is one consession I'm not willing to make.. Are there known pre-requisites... like BOINC 5.10.45, or running at stock clock that I'm unaware of? This was my first attempt at running Beta and I might be lacking in know-how. Regards, JDWhale |

Post:
Ehll would freeze over before Penny could load up with enough work. Another perspective on the whole issue that is taught at my former employer is that... "Diversity in the workplace is a positive." I think this mantra can be carried into the scheduling world. The last thing that the project needs is to always have the same sets of hosts paired together. From the validation perspective it is better to have the hosts "randomly" paired to limit introduction of possible patterns based on wingman selection. That sort of behavior could undermine the validity of results.... much like politics. |

Post: those are GREAT explanations, but it still leaves a question of refusing to work with certain people or at the least match the machine speeds and not have 1 wicked fast and one fossil slow working the same WU's. I think what you are asking for is too restrictive... What happens when 95% of the computers are very much slower than yours? You might not be able to DL work because all the WUs currently being assigned are already issued to slower computers. Would you rather not be issued any work than being issued work where your wingman is slower than you? Similarly, if 99% of the computers are faster than you, then you might not get work because you are too slow and no "compatible" wingmen are currently available. The schedulers are already complex enough and IMO restrict DLs too much when my hosts request work.... I have a host that continuously requests 7 days of work and are only granted 5 or less WUs per request. This host crunches 50 WUs per day and can only fetch 5 WUs per request! What you are asking might only allow a single WU to be DL per request... at that rate it might take 2 hours to DL the 100-200 WUs required to raise my cache to an acceptable level. That places too much burden on schedulers that are already overloaded. No thank you... Regards, JDWhale |

Post: Just my experience with the Q6600, the stock heatsink was horrible. I use an intel motherboard too, so no overclock, and I was getting very high temp readings. I just got a Zalman heatsink this weekend and it dropped my temps by 20c. And BTW-I tried the stock heatsink w/ silver thermal compound and it didn't help that much . . . It's pretty sad that a stock heatsink can't take full load w/ no overclock. I didn't have any heat issues with the stock HSF, even running a mild 5-10% OC on a Q6600 with ambient/room temps at 27C and inside the case temps of 34+C. Like you say... YMMV. The case was an Apevia X-Qpack Lan case... there wasn't room to mount anything other than stock HSF. That host would have been Wrongway until ~May 10... his performance is clearly documented.

Post: Hi, I agree with MSattler that you probably have cooling problem. Check again your HeatSinkFan(HSF) mount on your CPU. Be sure to use "thermal" grease between CPU and HSF. Get help from friend or computer shop if needed. Use a program like CoreTemp to verify your CPU is not overheating. I do not know if you are OverClocking(OC), but since you use stock HSF you should not OC until you verify that cooling is not a problem. Good luck, JDWhale |

Post: Maybe JDWhale would/should like to chime in here? Benchmarking the SSE clients is a relatively slow and tedious task... (I'm not being critical, just stating a fact). Personally, I do not have any P3s or compatable SSE AMDs. There aren't many testers over at Lunatics running the trials and of those that are, results have been mixed with the AMD times being, as of yet, rather disappointing. I share frustration with users waiting for a release and Jason, Raistmer and others in trying to find an acceptable solution. The work involved in building multiple releases a few weeks apart is substancial, Jason's methodology in testing/benchmarking incremental changes is time consuming, but would be required in both cases (that is release of both interim and/or "final" builds). This is a *much* bigger chore than the SSE2 build-test-release cycle, caused IMO, to the different chip implementations/behaviors of SSE/MMX instructions. That all said... I've enlisted the help of a single tester to run trials of incremental changes that I've been making to the client (please do not offer to test, my support of a single tester is enough extra work already). With the current progress, we're seeing ~10 results returned per week and not a wide variety of ARs. As such evaluation of crunched WUs are slow and yet inconclusive, but a major performance improvement, if any, will show up. Bottom line... We've not abandoned the SSE client... it's just taking longer than we all want to be evaluated and released. Kind regards, JDWhale |

Yes, I've noticed a few also, though they do not bother me as much as wingmen running old versions of BOINC and under reporting credit. If your wingman "errors out" quickly then there is no harm as the WU is resent to another host quickly. Just rest assured that your results are saved and the credit will come, eventually. Living in SE Texas, I too feel the pain of summertime heat and running the crunchers. Since they generate heat, they add to the AC costs...

Post: Im not havuing any thermal problems, and I have a slight OC at 3.2Ghz. I have tested against all prime and otherwise tests and come up fine. My full load temps are around 55C tops. Tj Max is 95C. Hmmm.... Well if you want an earlier build, you'll have to switch to running an Apple. You are running the first release of the AK V8 for Windows. Looking through your errored results, all I've seen failed with memory errors when you were OC'd to 3200MHz like you say. My first suggestion is to reset your motherboard to default settings and to run your CPU at factory speed. If the program still fails, then post back. If all runs well, then I suspect that you do not have a stable system when OC'd. Have you also OC'd your memory? It might need a slight voltage adjustment, different branded memories have differing requirements when being OC'd. You mention another team member having the same problems, is your teammates system also OC'd? Give them the same advice to try "stock" speed. Please remember folks... this code was developed for Apple computers which are built to strict standards with a set of high quality components. Running this application on the variation of Windows PCs and their hardware introduces many possibilities for failure, especially when overclocking. Good luck, JDWhale |

Post: As never trying a 64bit Windows system I can't really comment on that.Ahh I see, you must've been wondering what I was on about then ;). Typically the 64 bit apps on Windows show a significant speed increase over 32 bit apps on the same hardware+64bitOS, so naturally as co-porter I am curious if this applies on who's machine, or there is some factor that may need to be addressed for future architectures. I did query about his not running release 64-bit SSSE3x and was told that he was running Vista 32-bit... That the WhalePort client was the fastest that he'd found for the hardware/OS configuration. Unfortunately, I didn't have a way to build a PGO client for SSE4.1, I'm finding that PGO with IPO applied yields another level of performance that I'd like to have seen on the SKT. Also coming into play, though with minimal effect is the SKT only having 4 memory slots vs. MacPro having 8 slots... but then every little bit helps. Regards, JDWhale |

Post: I'm running a Q9300 just a tad O/C'd vat 2.8 Gzh. You might want to keep some records of CPU times vs. AR and try both clients(SSSE3 & SSE4.1), then decide for yourself which is better/faster. With such variables coming into play as memory speed vs. CPU speed and latencies, each system is likely to have slightly different results. With the Q9300's "limited" L2 cache, this might be one chip that performs better without OCing unless the memory subsystem is finely tuned. Also you might find one client performing better at some ARs and vice-versa. Of course, you could just relax... knowing that whichever client you've chosen is much faster than the "stock" client.

Post: The rule of thumb is that 10% of the code is responsible for 90% of execution time. SETI may not match that rule exactly, but that's the concept... How many places does the 90/10% rule come into play... In coding for sure, 90% of the code can be developed in 10% of the time... it's achieving the last 10% that breaks the back of many projects. From past experience in porting IrixGL applications to OpenGL we faced approx the same ratio... 90% of the port was completed in 10% of the time. Of course with OpenGL in it's infancy and not behaving according to the rules was a major challenge. Cheers, JDWhale A new app for Overclockers? Wouldn't that be something...Bet that would get a few peoples hair in a ruffle... I'm looking at different apps for differing ARs... maybe have 2-4 apps installed and switch between them, possibly via the app_info or similar mechanism, depending on the AR. [ducking for cover...] [Edit] That might not sound like I intended... The app is still capable of crunching all WUs, just different profiles (PGO) applied to optimize for different AR ranges, thus creating specialized apps for the work. [/edit] |

Posted 29 May 2008 by JDWhale
Post: Are there any tables or other benchmarks for target RAC based on CPU type? Sorry, but in the PC world there are too many variables to base RAC upon CPU type alone. Here are a few that must be taken into account: CPU speed, Motherboard, Memory speed, Client application. There are Q6600s in RAC range of approx. 2000-7000 depending on variables. If you were to select a Mac, the "target" RAC is much easier to predict as the system configurations are more standardized. Regards, JDWhale |

Post: Speaking of which, I do have a quad processor (@ 500 Mhz) XEON server I could run an SSE only flavour test client on if you're still interested. I also have a dual processor PIII Tualatin system (1.4 Ghz) that's SSE only I could power up. With your eval license expiring, I wasn't sure if you were still looking. The 4-way system only takes roughly 26 hours per WU, so it'd complete maybe four per day for investigating... All in good fun... I slowed down 3 of my hosts by "burning in" the SSE code a couple weeks ago. No problems with validation, no crashes. My work on the SSE code has been turned over to Lunatics, clients have been built and early tests have been run. PIII performance was boosted by 5-20% over 2.4V client depending on AR. Performance issues of running the SSE client on AMD systems are hindering a general release. I know nothing about AMD, folks are still searching for the best solution. I've attained more "evaluation" licenses from Intel and am currently learning & experimenting with other compiler tools & optimizations. BOINC on...on... JDWhale |

You seem to have discovered an "Easter Egg" I put in the SSE2 code... explodes when someone brags about passing a Whale ;-) Just kidding... my RAC might be higher if I'd abandon my coding adjustments and testing on a few hosts and just let them run "online" crunching 24/7. But I'm too busy trying to raise RAC for others. One side effect is that my own RAC isn't as high as it could be. Cheers, JDWhale |

Post: thanks guys ! but i still hate to lower my rac beacose of this game alone ! Well... if the game is really that compute intensive, you could tell BOINC to only run 3 WUs rather than 4 while you are playing the game. Then when you shut down the game just switch back to 4 WUs crunching. Might give you the best of both worlds... still crunching while you're playing without blocking. Goto BOINC Manager menu->Advanced->Preferences... Select "Processor Usage" tab then adjust "On multiprocessor systems, use at most XX processors" to be 1 less than the number cores you are running.

I may have to get round to loading my Vista 64 that's been sitting on the shelf for about 12 months and I've been avoiding like the plague ;( I've read on these boards that Vista cuts performance by as much as 10%, that XP is the better crunching OS. Of course, I've never held that view... There is no way that Thurston would gain another 10% by running XP. Also, caveat emptor when reading the reported clock speeds, we know they can be reported artificially low when you start adjusting the multiplier. |

Post: ======== S_S_E_____U_P_D_A_T_E ======== Well, my second set of Intel Evaluation licenses for compiler(ICC) and Performance Primitives(IPP) has now expired. With this event, I've had to stop further development on the SSE capable client. All is not lost... preliminary clients have been built, it seems from early benchmarks that PentiumIII hosts will benefit over KWSN_2.4V_SSE_MB. AMD based SSE hosts do not seem to show any benefit (possibly quite the opposite, showing performance loss). Since I do not have any SSE only hosts, I have relied on 3rd party, limited testing. In any case, I've posted my code changes over at Lunatics for possible inclusion to the source code tree. Also included in the updates is code that ports a previous Core2(SSSE3) only optimization to run on SSE and above. I've seen benefits on my SSE2 and SSE3 hosts, especially on VLAR (63.98CR) WUs gaining upto 10% over release AK SSE2 client on Gilligan. Whether this optimization will benefit SSE hosts is questionable... This optimization tickles parts of the SSE port that uses MMX code and requires an extra step to protect the FPU from corruption (translation: MMX switching is SLOW). Anyway... without a compiler, I'm done coding! Also, my evaluation installation of "Microsoft Visual Studio 2005 Professional Edition" expires in 21 days. I don't know if I can renew the evaluation license for that product. Yes, this is a required product for SETI client development on Windows Vista. Regards, JDWhale |

How to DL more work ?
(Message 755891)
Posted 20 May 2008 by JDWhale
Post:
Sorry, but no difference here with host Wrongway. This host completes ~4 WUs/hr, I try to fetch 200 WUs every other day. Today was requesting ~300 hours work and fetching 16 WUs/request rather than full 20 WUs/request. My hosts do not crunch any other project and I don't fiddle with parameters like DCF. Why doesn't the full allotment of 20 WUs/request get filled on this host? Regarding my host Lovey referenced at the beginning of this thread. This afternoon I brought her back to life after being "down" for 10 days. I do not expect to miss any deadlines from the ~300 WUs in her cache. So I still can't figure why the project rejected her request for more work 2 weeks ago with the lame excuse of "won't finish in time". She has been down due to a failed power supply for 10 days; Comes back online mounted on a lesser motherboard and still will not miss a deadline! I'll revisit this subject once Lovey' cache is depleted and she is requesting work again (in about a week). Regards, JDWhale |

Post: OK, you experts out there; riddle me this one then. Right. I've noticed cases on Gilligan where WUs with ARs of 0.409830 & 0.435152 repeatedly have CPU times of ~14,233 & ~13,362. Even though the WUs would show up in the same "bin", CPU times vary significantly with minor AR fluxuations. Since the WUs tend to come in groups of same ARs, the binned data can easily become biased with a particular ARs data. A tightly zoomed in scatter plot might be a beneficial display for analyzing data in question. Good luck with your memory OCing. Be careful, memory can overheat and cause problems without proper cooling. Happy BOINGing, JDWhale |

I'll do the release client first, but I also want to try two others for comparison. Maybe ~24 hours each, maybe longer if needed for similar ARs. Keep in mind that Jason sprinkles magic dust on his computer and recites ancient incantations while building the releases to give them a little extra power ;-) (So my personal builds would be slightly faster if Jason had build them.)

As luck would have, I get to test this statement. Last night, Wrongway lost his power supply. Today, I'm doing the CPU/MOBO shuffle. Wrongway and Lovey are going to swap Mobos and I'll leave Lovey down until I get a replacement PS (no hurry, I'm a budget shopper and that case requires a special "shallow" PS), or finish up modding an old Dell case to house Lovey with the proprietary Dell PS. I was intending to make this move for some time... These CPU and MOBOs have been mis-matched since March 9, when the WU from ehll burned up Thurstons Mobo and I last did the CPU/MOBO shuffle. Maybe SETI project knew somehow that I was going to suffer PS failure, and thus denied work with the "(won't finish in time)" message ;-) Damn! BOINC is good! Regards, JDWhale |

I can crunch other (shorties for example) WUs for a whole week without touching anything in my queue and still not miss a deadline. I could even turn Lovey off for 7-10 days and not miss a deadline. Shorties DL'd would simply be crunched at "high priority" so not to miss deadline. At least that is the way they are usually handled when DL'd deep into the queue. Another host, Wrongway, is showing the same symptoms, only fetching 9-11 WUs/request. Wrongway started running the AK port ~1 week after Lovey started. Tomorrow I'll nudge Thurstons cache up a bit from 5 days up to 7 days worth of work (~700WUs). He was able to sustain that level and still DL 20 WUs/request a month ago when he was racing to catch the Skulltrail... I'll see if he can still do the same now, after 5+ weeks running the AK port. @Ned - My "connect every 0.0 days" indicates "always connected", IIRC, so there is no reason not to DL because of this. 'Til now I have left DCF under program control (currently DCF=0.125966], never changed its value manually. I'll wait a couple days before requesting new work, then lower the DCF just a bit and see if that helps to DL more WUs/request. Still confused, JDWhale |

Post: Maybe a hint why Lovey can't fetch 20 WUs/request. Note the message about "won't finish in time" in below "messages" excerpt...

So SETI scheduler/server is wrong in its assessment of what Lovey will complete. It is not a problem with my settings... rather a problem with Berkeley/BOINC servers.

Post: If you have time, can you post a status update on SSE2? ==== S S E 2____S T A T U S____U P D A T E ==== Well.... Gilligan has been crunching slightly different builds of the SSE2 code as applied to the Lunatics release the past 3 days. Next set of 4 results due to be uploaded in about an hour (~18:00 UTC). Unfortunately, not many results to view as they get purged ~24 hours after being reported. The fastest client so far seems to be SSE2x ("Xeon" optimization), the next cycle of WUs will be running with "O3" compiler optimized SSE2x client and will commence when the current cycle finishes. Each cycle takes ~18 hours to complete, thus the results are being reported about once daily. My code for SSE2 has been delivered to Lunatics and is scheduled to be applied to the code base and tested when time allows. Regards, JDWhale @Fred - I think Gilligan is getting ~5 WUs (VLAR & MidAR) per day with the AK optimized client. |

Post: They look okay to me... except for that "-1.0" for connected, but that's the same value Thurston shows, and he DLs 20 WUs/request. I agree... Yes... my other hosts fetch 20 WUs per request. <duration_correction_factor>0.128427</duration_correction_factor> Runtime estimates for ~300WUs in cache are 1:11:44 - 1:16:02 +2 reissued WUs have longer estimates of 1:49:13 & 2:42:05 But your mention of disk space might be instrumental in resolving my issue. This host runs "diskless", boots from SecureDigital USB flash memory and installs BoincPE to run from a 768MB Ramdisk (host has 2GB RAM). I just bumped the Boinc allotment from 250MB to 450MB, and proceeded to fetch 9 WUs/request. There is still 637MB free on the Ramdisk (Seti project directory is now 133MB in size, ~300 WUs, ~6.5 days cache) Values in Disk & Memory Usage of Preferences... Use at most 0.45 GB disk space Leave at least 0.00 GB disk space free Use at most 100.00 % of total disk space Write to disk 60 seconds Use at most 100.00 % of page file(swap space) What remains a mystery is why the number of fetched WUs is changing... the prior Preference values were constant for at least the past 7 weeks... since before I went to Las Vegas 23 March. I've now allowed space on Ramdisk for ~1500 WUs (450MB)... So I think there is plenty of room to fetch 20 WUs per request. Unless there is something I'm not taking into account. Boinc version is 5.10.30 - I can try to update, but it's not straight forward with BoincPE... I don't want to reburn the USB flash just yet. (Maybe soon, when I do the CPU/Mobo shuffle and need to rename hosts to match CPU.) Also, it always seems that as soon as I update BOINC, a new version gets released, making me instantly obsolete again. Maybe Berkeley is trying to ween BOINC version 5.10.30 hosts by cutting the WUs they are issued, If so, I'd rather see BOINC version 4.45 hosts weened ;-) Thanks, JDWhale |

I could tell you how, but then I'd have to [you know what I'd have to do!] you. ;-) I don't like those restarted "hybrid" crunched WUs that occur when you shutdown BOINC to switch clients. Folks monitor my hosts, I want to keep the WUs purely crunched by a single client, so not to introduce "outliers". Regards, JDWhale @Robert W Johnston - I'd give you a direct link, but IDK if you want SSE4.1 or SSSE3 version... check the "sticky" thread 2nd from top of NC forum.

Post: in my original post i did not mean any disrespect of the developers of the AK V8. None taken... I'd first looked at porting to SSE2 about a month ago... right after AK_WhalePort V0.2 was complete. The "intrinsic" code was confusing at first, I made a bad decision, chose a wrong path and got discouraged. As with most my porting efforts, I've found that the first attempt is usually not sucessful, but a great learning experience for the next attempt. Now with all the release testing over and my goal of getting Thurston into the "Top 20" achieved, I renewed my "evaluation licenses" from Intel and decided to take a second look at what is required to build AK SSE2 client. No longer intimidated by the SSE intrinsics, I see the solution is both simple and elegant. I'm confident my latest build will pass acceptance tests and I'll start crunching AK_WhalePort V0.2X (SSE2) on my P4M Northwood(1.6GHz) laptop shortly. Kind regards, JDWhale |

Post: Pity you had to get teamed up with an anonymous 4.45 for that WU - he has at least one other in his pendings that has had to be re-issued on account of non-validation. I'm certain that not validating was my fault... I ran the acceptance tests on Thurston for the SSE2 client rather than on Gilligan before going "live" with that WU. After failing to validate, I then ran the acceptance tests on Gilligan(~4 hours) and sure enough some failed. Looks like Gilligan has a few VLAR, and MidARs (both sides of 0.4)... both posted and in his queue... I hope to snag a few VHARs currently being passed out to round out the collection. ==== S S E 2____S T A T U S____U P D A T E ==== I located/fixed what I think was the problem with yesterdays client (oversight on my part), and am now launching the 4hr acceptance tests on Gilligan with 2 new clients.

Now I'm crashing at the end of my simple WU instead of at the beginning. anyway... point is: I've desimplified some of those SSE3 calls to SSE sequences... example: p1 = _mm_hadd_ps( f1_1, f1_2 ); becomes p1 = _mm_add_ps(_mm_shuffle_ps(f1_1, f1_2, 0x88), _mm_shuffle_ps(f1_1, f1_2, 0xdd)); and cd1 = _mm_addsub_ps(cd1, td1); becomes cd1 = _mm_shuffle_ps(d1=_mm_shuffle_ps(_mm_sub_ps(cd1,td1),_mm_add_ps(cd1,td1),0xd8), d1, 0xd8); Also, these macros work for a couple others... #define _mm_moveldup_ps(X) (_mm_shuffle_ps( (X) , (X) , 0xa0)) #define _mm_movehdup_ps(X) (_mm_shuffle_ps( (X) , (X) , 0xf5)) So..... if anyone wants to pick this up and have a go, the above might help you get started... Back to trying to get this thing to run on my P4M (Northwood) laptop. Regards, John |

Post: Just some trivia for an old P4 Socket 478 3.2GHz oc'd to 3.6GHz running the KWSN 2.4 code here. I have now upgraded to the SSE3 AK V8 port and we'll see how it progresses...... FYI: My 3.2Ghz Prescott Ginger is approaching RAC 1000 after 3 weeks back online with the SSE3 AK port. Hmmmm.... Ginger results only show... Speed: 1 x 3200 MHz even though HT is enabled and is crunching 2 WU at a time... I see yours reports similar. So that must be "core count" and not "thread count" reported, a little misleading.

Post: and I think I may miss the deadline to send the result.is there a way I could get this sent to my current computer, so as to not miss the deadline? One of your hosts reported a result within 3 minutes of you posting this message, so I'll assume that you refer to your "other" host as being "down". I wouldn't worry too much about it since that host only has 1 WU currently "checked out" for crunching. BOINC projects are designed to handle missed deadlines, that WU will just get reissued to another host when your deadline passes without reporting results. Kind regards, JDWhale |

Your quota is 400 WU/day/host... It looks like you have your settings to "always connected" and cache set to ~3 additional days if even set at all. Of course I'm often wrong in my analysis. Your hosts will be able to crunch ~90 WUs/day each... So you will not meet your quota with your current settings... just steadily DL ~100 WU/day to keep ~300 WUs ready to crunch. BOINC On...On... JDWhale BTW... I've backed down Thurston OC to 3200 from 3375 MHz and watched my temps drop ~10C (59-52-55-57) room temp 28C. Also of note is that power draw has dropped from 256 to 200W, saving me $3.25/mo (25%) on electric bill for this host. |

But then, I am comfortable with the way I operate my hosts and would not encourage others, less comfortable, to do the same. Maybe, rather than running it all the way out, set it so that you'll only lose 0.5 - 1 days work if sonething goes awry when you switch over. Regards, JDWhale |

Post: It's nice that faster processors are getting cheaper. The bad thing is, that almost always, one has to buy a new motherboard and new memory to take advantage of (or even fit) the faster processors. True. But didn't Intel introduce the "Slot 1" to get away from the need for new Mobo to take advantage of newer processors ? Or was there another reason ? Granted that was a few generations ago, but seems the technology still only lasted for one generation... Just another marketing gimmick to get you to buy another motherboard. IMO.

Post:
Like dcappello points out... If you live near a "MicroCenter", the Q6600 deal for $199(US) is a great price and has been available "instore" for the past 2 months, I bought one in early March. For those of us who are budget minded, like ME, a "no frills" system can be built by combining this chip with the GigaByte GA-P35-DS3L mobo ($100) and 2GB cheap DDR2-800 memory kit($50) and cheap graphics card for ~$550 total. Full time crunching on 4 cores at stock 2400MHz draws < 170 Watts. Same power consumption as my 3200Mhz Prescott, but easily 500% the performance. In my opinion, it's cost effective to retire the power hungry computers of yesteryear and replace up to 4 individual system with a single newer generation computer. In addition to less heat, lower power, simpler to manage, this solution is also quieter. Donate the old systems to your church or childrens day care for possible tax deduction. Regards, JDWhale |

WUs still pretty much in-sync with all 4 starting within 5 minutes of each other. Draw normally staying within 253-258W range. Kill-A-Watt sampling begins 5 minutes after last RC1 client starts. Draw averaged over 3 hours. Thurston - 243 Watts 27C KWSN_2.4V_SSSE3_MB Observations: Watching the Kill-A-Watt, first 1/2 of WU was reading 246 Watts... last 1/2 draw was 238 Watts..... I didn't believe, so I closely monitored when the 2nd round of WU started up... I watched draw rise from 235 Watts at the tail end of all 4 WUs to 246 Watts when the 4 new WUs were crunching. Similarly when 2nd round of WUs reached 50% completion draw fell to 236 Watts. Power draw is averaged over 3 hours. Thurston will remain running RC1 client for next ~60 hours to compensate for running these tests in quest to reach RAC 7090... Regards, JDWhale |

I guess with the increase of the app. this will not matter that much. In the interest of checking difference in core temps & vCore droop, I propose to divert Thurston to run R-2.4V SSSE3 client long enough to crunch 2WUs/core. (~4 hours) I'll follow up by running RC1 SSSE3X and post Core_Temp and CPU-Z screen caps to show temps & vCore idle and under load with each client... Anyn interest in this set of tests ? Might this information be beneficial? Regards, JDWhale @john deneer - Agreed. My room temp is 27C, case open, I'll snap the caps when the AC isn't blowing. Also I'll supply power through Kill-A Watt to get system draw. |

Post: With Who?'s experience, is this suggesting there is an issue with the Crunch3r BOINC Manager (6.1.x) and the ported Alex code? I don't think so... Rather a Vista/BOINC issue... When I first noticed an issue with ~6 WUs exiting with errors, I didn't think much of it. Looking back at the exit code (0x40010004) and googling it, I see this in a BOINC FAQ: [FAQ: exit code 1073807364 (0x40010004) (on Windows Vista) Is this related to the subsequent canceling of all the WU's in the cache? I can't say, but I think the 2 events might be related. My question to the few who are following this thread... Please report if you've had similar experience so we can reasonably disqualify v8 ported code, AK_WhalePort, as a probable cause. Granted there are not very many VISTA users out there and the conditions for the error as reported in the FAQ is "Shutting down VISTA while BOINC is running". |

Post: crunch3r BOINC manager and the V8 port looked like they did get mad together ... all my workloads are gone in error. I am sorry, but maybe a blessing with all the detatched WUs. After the "detatched" WUs are reissued to new wingman and reported back, then you would get 0.0 credit. This "error" will cause you to start fresh, without detatched WUs in your cache. One of the first WUs to show error may have clue to failure: exit code (0x40010004). That error is diagnosed in this thread [Vista] Avoiding client error exit code 1073807364 (0x40010004). I don't know if you can relate, but might be caused by Vista shutting down too quickly for BOINC. Regards, John |

Post: [edit]message deleted[/edit] If you crashed... Mark had mentioned he needed to raise vCore a bit to account for the extra stress being put on his OC penryn with the new client. You probably have more information/resources on that requirement than I could help with. Check your BOINC log. About 4 days ago Thurston suffered from a "random project reset" where all WUs were deleted and detatched. More details on this were posted to this thread... like I said about 4 days ago. Since then I pointed a small fan directly on my memory and adjusted vDimm18 a bit. I don't have a lot of confidence in my BALLISTIX DDR2-1066 dimms. Looking good, John |

Post: With the release of the new app's about 1 week away, I have one question. I'll try one example... When wanting to find the MEAN of a vector(1D array), typically a programmer would write ~5 lines of code to loop over the all the elements to gather a sum, then divide the sum by the vector length. Simple enough and easy to read/understand, even for most non-programmers. Alex code might implement the same operation using maybe 100 lines of code, split the array into 4 or eight pipes, feed the "vector" part of the processor allowing 4 or 8 sums to take place in the same amount of CPU clicks as a single sum operation. Accumulate the sum from the separate pipes, then do the division. Not very intuitive, but making much more efficient use of the CPU and making the code much more complex to read and to write and to comprehend. Also requires coding some of the optimizations multiple times, once for each CPUs capabilities to gain maximum performance on each CPU type. This process uses what are called "intrinsic functions" that allow "low level" access to the CPU capabilities. This set of intrinsics change from CPU to CPU and are sometimes refered to as SSE, SSE2, SSE3, SSSE3, SSE4.1, MMX, ...etc. Explaining the need for more than one client, depending on which "instructions" your host(CPU) can understand. This was just the most simple of examples of how Alex speed up the SETI client. Regards, JDWhale [edit] The Skulltrail has changed hostid and "detached"... hostid=4262769&offset=1800 [/edit] |

Post: I will pull the plug on Ginger when her cache empties in a couple days. Summer is approaching quickly here in SE Texas. Room temps are at 27C and Ginger stays in heat. Coupled with her energy draw puts me over my project budget of 1kW since Wrongway came online. She may be going down, but she is not going out. Is destined to my 21YO daughter come June. My focus is now pointed at "burning in" the release candidates so there are fewer (hopefully none), surprises upon release. I'm trying everything I know to break RC1... Used it as a coffee holder one morning... Had it fetch the post another...Manning the BBQ last night... Solid as a rock! We're talking "Top Shelf" stuff here. and have refrained from cancelling WUs where my wingam was running BOINC 4.45. I hate those... and sometimes you get a gaggle of WUs with the same wingman, who happens to go missing leaving you hold the pending bag for a couple months. Yes, modus operandi(MO) for Thurston avoid most "pending" pitfalls as credit is usually granted when the result is returned ("checked but no concensus" is the exception). As such I would expect RAC to stabilize 2 weeks after change is applied as long as he doesn't run out of work. That is one of the pitfalls of this MO. Without many pending, his RAC will drop like a rock when the work runs out... Thus a large cache is essential. Without another interruption, I expect Thurston to reach stable RAC in about 72-96 hours, target is still RAC 7090. G'Day, JDWhale |

Post: bump With the switch to RC1 SSE3 estimated RAC should be updated once again for Skipper, Lovey, and Wrongway; but I haven't plugged the data into my unofficial guestimator yet. Sorry still no updated estimates for RAC on these hosts. I've been busy trying get the holes on the data samples filled on Lovey to paint a more complete picture by our wonderful statisticians. With my running Lunatics RC1 on these hosts I agree that the value of AK_WhalePort displays are becoming of less interest. With the data painting a nearly complete fill(given the availability of variation in WUs), monitoring of Skipper, Ginger, Lovey and Wrongway should be terminated at your discretion. FYI : I will pull the plug on Ginger when her cache empties in a couple days. My focus is now pointed at "burning in" the release candidates so there are fewer (hopefully none), surprises upon release. A brief update on 2 of my hosts: Host = Wrongway: Q6600 @ 2520MHz  06Apr My estimated RAC = 4700 13Apr My revised estimated RAC = 5040 23Apr Newest revised estimate RAC = 5400 I realize that Wrongway is now running RC1 SSSE3X flavor, this fact has minimal (if any) impact on my evaluation. My earlier estimates on this host were intentionally conservative. This RAC 5400 number is the number you should expect if you are running a "stock clocked" Q6600 with DDR2-800 dual channel memory and the new client. Host = Thurston: Q6600 @ 3375MHz  06Apr My estimated RAC = ~7400 13Apr My revised estimated RAC = 7080 Recovery from the "Random Project Reset" 3 days past was fairly smooth, helped with the immediate DL of 80 reissued WUs that I used to my advantage to minimize "pending credit" build. Please understand... I am not using BOINC default schedueling with Thurston. I am employing techniques to minimize pending credits. I have only cancelled a couple WUs that were already validated by late wingmen and have refrained from cancelling WUs where my wingam was running BOINC 4.45. My employed methods are intended to reach "final stable" RAC in as little time as possible and are not intended to inflate RAC beyond what would be attained with more available time. YMMV Estimated RAC 7090 remains for Thurston. This should be your expected performance of a Q6600 @ ~3300MHz with DDR2-1066 dual channel memory. FYI: On the jukebox Frank by "Amy Winehouse"...

[Edit] Post # 777 Wish I was playing the slots... [/edit] Maybe you refer to result like wuid=249775937. I understand, simple mistake. You only get "extra" credit if your wingman also "overclaim".

Post: JD; Thanks for the offer... First a question back at you... Is your signup date really earlier than mine? I find it hard to trust anyone claiming to have joined the project before me. Just kidding.... With the pending release the new Windows clients only about a week away, It would be hard to gather a meaningful sample in the limited time. The folks monitoring hosts already have more on their plate than they can comfortably chew. Add to that the requirement of your being able to switch between OSX and WindowsXP/Vista on your MacPro as/when directed make this a difficult proposition. I hope you understand, JDWhale [Edit] Wait just a minute... I just spotted you at #30 spot and rising really, really fast. Does your Mac do Windows? Maybe I can sidetrack you to allow me to get even further up the ladder ;-) [/edit] |

Post: Thurston is positioned at #21 on the "Top Hosts" list as I write this. With some help from our fallen friend, #20 appears guaranteed within the next day or so. There is one host I'm in fear of jumping in ahead of me, UL1' Big Mac. Though currently sitting in #31, this host has the ability to leap several spots when fed the proper diet. I am begging The Curmudgeon to throw down the gauntlet if need be. Do not let Big Mac past. The quest continues, JDWhale |

Post: I know it's not related to your App JD, but on the Mac Pro, generally units of the same AR take within 200 seconds of one another to complete. If you look at any group of results for the Mac Pro you will find that finish times are very similar to one another. That is exactly the point I was trying to get across... In QS case, by switching to the Mac "xeon" client he is seeing a similar "narrowing" in the range of CPU times compared to when he was running the "core2" flavor in the same bins. Of course this observation is made with only a limited # of results reporting. The ranges could spread as more variety of ARs within the bins are crunched. A scatter plot, with points representing each result and vertical lines representing bin boundaries would bring more meaning to the range of CPU times per bin with these preliminary results. ( Just what our excellent chart people need to hear, more extraneous drivel from the peanut gallery ;-) [runs and hides before someone can toss an eraser at me] Cheers, JDWhale |

Post: Notes: Thanks for the new format, There is quite a bit more information and it took me a couple glances to really see the benefit. I like it! From this it can be seen that the mean values from the relatively few Xeon results so far would seem to indicate better performance than Core2, but that all the results for Xeon are between the max and min times for Core2 in any given AR band. This demonstrates the caveat that I have so often quoted. What I see, with the limited data so far, is that the Xeon client CPU times are more consistant (within a tighter range). Possible explanation for this is lesser influence by other process running on the host. I would expect the bars for the Xeon to extend downwards as more readings become available over the next few days, pulling the mean value down to demonstrate better performance. But only time will tell. Maybe, but if the CPU times remain so tightly grouped and less than the Core2 mean, doesn't that also indicate better performance?
Touche... |

Post: Just the facts! This reporter has just been informed of The Definitive Answer to the longstanding question of : Which client is faster on the same hardware: OSX or WinXP ? The pretty pictures will follow, but I'll give a brief account of what I have been made privy to... It is too close to call!!! It is a "photo finish" folks. DO NOT TEAR UP YOUR BETTING SLIPS!!! We are waiting for the photos to be developed. Personal thanks to :

Post: It will be an interesting 4-6 weeks after the Alex code port is released to see how much the hardware can be pushed. It may also give an indication of any limitations due to the OS, within experimental error. Interesting few weeks indeed. I wouldn't be surprised to see a slight shift in which hardware configurations (speeds{cpu,fsb,memory}, fine tuning, L2 cache sizes) perform best. Client choice might become a bit confusing. I doubt I'll get in too much "hot water" with the Lunatics by leaking here that a great deal of analysis is being performed on benchmark results from the testers (self included as tester) in order to present as clear a choice as possible for which client provides best "overall" performance on your hosts. Different clients might be better at certain ARs than others and vice versa. Thus overall performance might vary depending on the WUs being served and chosen client. Keep on BOINCing, JDWhale |

Post: How about a weekly update with just minimal babble... With the switch to RC1 SSE3 estimated RAC should be updated once again for Skipper, Lovey, and Wrongway; but I haven't plugged the data into my unofficial guestimator yet. We should be seeing some updated plots/charts if/when the data fills in the AR bins. Host = Skipper: P4D-820 @ 2800MHz  06Apr My estimated RAC = 1280 13Apr My revised estimated RAC = 1342 Host = Lovey: E4500 @ 2420MHz  06Apr My estimated RAC = 2300 13Apr My revised estimated RAC = 2720 Host = Wrongway: Q6600 @ 2520MHz  06Apr My estimated RAC = 4700 13Apr My revised estimated RAC = 5040 Note here... As I'm writing, Wrongway is still running benchmarks for the Lunatics crew. After review of said benchmarks, I'll switch BOINC to run an RC1 client of my choosing (probably the one with the best performance in the mid-AR WUs we're seeing so many of. Warning : if there is an onslaught of VHAR or VLAR WU's I won't hesitate to switch to the best client for the data. Same holds true for Lovey. Host = Thurston: Q6600 @ 3375MHz  06Apr My estimated RAC = ~7400 13Apr My revised estimated RAC = 7080 Remember - Random unattended "Reset project" ~40 hours ago :-( At least it's going in the right direction! However tempting to switch... Thurston will remain on AK_WhalePort V0.2X until official Lunatics release... I want to see how accurate my estimated RAC of 7080 is. Host = Ginger: P4-540 (Prescott H/T) @ 3200MHz Sorry, Ginger is in the powder room and doesn't want her picture took. Trust me, her graph is climbing, but since she's been switching between KWSN R-2.4 (SSE3) and AK_WhalePort V0.2S (SSE3), and now running RC1 (SSE3), it's not a reflection of a single clients performance. Trust the charts/graphs posted by the experts. Regards, JDWhale |

Post:
The "Xeon" clients actually only refer to an additional AK optimization that at the time might have been intended to steer clear of Core2 with the limited L2 cache, etc. Intel has released so many variations of Core2, the optimization might now have a name other than "Xeon". Yes, The AK_WhalePort Xeon is/was faster than the Core2 build... After building SSE3 for Ginger & Skipper, I never thought to try SSE3 on Lovey. Until I ran the benchmarks on the new Release Candidates (RC) last night I didn't think that SSE3 would benefit the E4500 Core2 Duo. My numbers are mixed, thus I'll be running each of three new RCs on Lovey.. My guess is the smaller L2 cache might benefit at some ARs with SSE3. I thought others might benefit from my experiments when it comes to choosing the "best" client for some of the more economical Core2 Duos. As Murphy would have it... I was going to post my findings/results at Lunatics first thing this morning, but I've been exposed. (Jason might not let me "sample the cookie dough" next time :-( ) I'm considering a similar test for Wrongway, but you didn't hear me say that. Thurston is out of the question, he is staying 100% AK_WhalePort in his quest to the top 20 (then there might be a change). Cheers JDWhale |

Post: A message of comfort to those running SSE3 but who can't run SSSE3 ... Can't slip anything by my ol' buddy Fred W. [...mumble...grumble...] While running one of my convoluted benchmark ideas, I switched to running the latest SSE3 release candidate inside BOINC (single process only) on both Ginger and Skipper for a few hours as your detective work points out... I'd switched back to running AK_WhalePort V0.2S after the benchmarks run on both hosts as further detective work will confirm. Since being discovered, I'll now switch back to running the new SSE3 release candidate for a good portion of the day, this time on both processes live. This should help stabilize the numbers a bit, though I doubt there is much variation in WU ARs in the queue. I hadn't looked in detail at the "numbers" you've quoted. "I couldn't see the forest for the trees", so to speak.... Details...Details...Details. If you wouldn't mind, please keep an eye on Lovey also. Preliminary benchmarks on the E4500 chip are mixed, so I'll be running 3 different release candidates (SSE3, SSSE3, SSSE3X) here... your pictures will tell a better story than I can gather only by looking at the numbers. Happy Sunday/Monday as applies, JDWhale |

Post: Thurston might have just caught a break... He DL'd ~70 resends of WU's that had past deadline or had problems DLing, etc. That works out to be ~18 hours worth, so I bumped them to the head of the queue. This might help offset starting with a fresh cache and slow the climb in "pending credits" a bit. The WU names all looked fine using "explorer", all looked fine in "client_state.xml". I'm pretty sure almost all were ~XXMar08YY, the new stuff. Step 300-500 hundred WU's into Thurstons cache and browse amongst the "detatched" WUs. They were all DLd over the past week 11-18 Apr. What causes a random unattended "Project reset"? Could be memory error, or maybe a "Vista" issue. I'm pretty sure the odd WU names were locally generated by a run awry BOINC. If others have had this issue, maybe it's a bug in the OS, If I'm an isolated case I might point to memory error. If it happens again, I'll be sure to run memtest before proceeding. Hmmmmm.... A closer look shows a definite pattern. The same WU names starting and ending at 1 minute intervals. Here is a longer snippet from the end of the event.

Adjusted "DCF" to the value host Wrongway has and Thurston hit the ground running... I'll expect a bit of a hit to show up in the RAC graph for the next couple days. I hope this RMA'd BALLISTIX memory isn't showing signs of failure. @Joker - "But I haven't got a wiscence to shoot a fwickaseein wabbit." @The Gas Giant - I'm offering Who? a chance to run AK_WhalePort if he desires. I'd really like to see how it performs on the SKT and don't think I'd run into those pesky "licensing issues" if he runs the client. Back to bed for me... JDWhale |

Post: @user formerly known as "Who?" - If you're following this thread I wish you the best of luck with your code... (It is fun to have your "own" version, isn't it?) I'll try to nip this in the bud... I honestly do respect Who? and his effort and will stand for no Who? bashing! If I came across differently, I am truly sorry I gave everyone a glimpse at that message. If you are a coder, there is a bit of satisfaction in 'having your own code' to massage and tweak to your desire, experiment here, experiment there, what works, what doesn't. That is the only message I wanted to get across. Who's effort differs very much from the "direct", or "verbatim" port that I did with AK_WhalePort, rather it is my understanding that Who? chose a more difficult path by trying to bring Alex optimizations to the current KWSN (V-2.4) structure. A valiant effort and much more difficult task than what I tried to do. Please welcome Who? if he chooses to join us, if not then please let him be. I want no Who? bashing in this thread, only constructive observations. We all want to crunch WUs at "light speed", there is no telling where the next breakthrough will come from. Regards, JDWhale |

Post: Thurston got jealous seeing PC1' picture on the internet and wanted his "Mug Shot" posted as well. As I said earlier, 3 hours downtime Wednesday so Thurston could relocate into this CoolerMaster case. The Thermalright Ultra 120 Extreme draws fresh air from the intake fan on top and blows to the exhaust fan on the rear. For extra cooling in the summer months, I'm thinking of putting a block of ice on top of the case above the intake fan ;-) Yep, he was crunching when this pic was snapped, it just looks like the fans are standing still.

Post: Well so far the elevated motherboard is as Free of dust as is possible(23" above the floor). And I even have room now for Dominator type ram dimms now. Looking good... With that orientation, fan pointing down, I just don't see how you mount the fan after mounting the HS to the mobo, that rubber in the top left near the mobo that fixes the fan to HS seems impossible... And if you mount the fan to the HS before mounting the HSF assembly to the mobo, I don't see how to apply pressure (even with the "common" screwdriver) to the push pin locking mount in that same upper left corner (this also makes using backplate next to impossible, IMO). How do you do it ? [Afterthought : I think I see how... You pull the PS for extra room up there ;-) Not an option for me, because I prefer cases where the PS mounts at the bottom:-(] I might have to drive down from Las Vegas in about 8 weeks and have you show me how you do your magic on PC2 or PC3 when they get their new HSF. (Just kidding, 4 hours across the desert at the beginning of summer isn't the right conditions for a whale ;-) Cheers, JDWhale |

I'll just add that Thurston was running @ 3200Mhz until 7 Apr 2008 19:59:11 UTC when he was bumped to the present speed of 3375. There is no "Crunch3r" data for current settings and a great deal of the AK_WhalePort data might be from before the switchover as well. Regards, JDWhale |

LOL Correct, here is resultid=815986757 from my host Thurston (Q6600@3375Mhz), probably a closer compare to your OC E6600 than the other host I pointed to earlier. Look at the line "Version info:". Happy crunching... @John Galt 007 - I would share how I switch over without even stopping BOINC, thus no hybrid WUs, but it's not for the faint hearted and requires impeccable timing.

Post: I believe that we have shown within error tolerance that the "different clients" are very close in performance. (Extensive offline benchmarks have been run that show the clients are within couple percents on the same host). This comparison between Marks HARV and my Thurston is going to show the difference between memory configurations Thurston is running dual channel DDR2-1125MHz, HARV is running single channel DDR2-760. Yes, this is exactly the hosts & clients I wanted to see. When I first hinted at this match up, I didn't know that Mark had hobbled his Q6600s memory and thought the matchup would be much more even. I think that I agree with your prediction, there will be even more significant disparity on VHAR WUs. Lesson to all being made at msattler expense. Optimize your memory. I think this is one place that the Macs have advantage over other PCs. The MACs are built to specification, whereas many of our "other" hosts are just thrown together without tuning the components.

Post: I run the Xeon client exclusively because my FSB more matches that of a Xeon machine than a Core2Duo Mac (since they're laptop CPUs). Alex's Xeon port hasn't been updated since October 7, and Harpertown Mac Pros didn't come out until sometime after that. Low End Mac says Harpertowns came out January 8, 2008, so we're talking about a 3-month difference. From what I can see you are running the "Core 2" client, but of course I'm wrong quote often. I agree with you that it is the "#define compiler conditionals" that make the differences and alter the same source code to compile differently for each version. It sure is hard to read the first time through, if you know what I mean. OK... The reason I asked was when I look at the "version" line in stderr for your Mac E6600 I see this Version info: OS X SSSE3 (Intel, Core 2-optimized v8-nographics) V5.13 by Alex Kan This line only gets to stderr in the version of the Alex code I have when the "#define" for "USE_I386_XEON" is not enabled. When both "USE_I386_CORE2" and "USE_I386_XEON" are #defined, then you get the message Version info: OS X SSSE3 (Intel, Xeon-optimized v8-nographics) V5.13 by Alex Kan When both these directives we see the "xeon" message to std error and performance boost on all Core2 hosts. This is why I ask if you have tried the "xeon" client. Does what I'm saying make any sense. BTW - I haven't had the opportunity to try the code on a Harpertown yet, let alone a Mac Pro 8-core Harpertown. My first guess is that the Harpertown on OS-X will outperform on VHAR, but will underperform slightly on mid-angle ARs. Possible because the CPUs were released too late for Alex to optimize in time.

Post: But at the end of the day if you guys think what you have is good enough ok. I don't see anyone saying you aren't helping out. You are entitled to your opinions. As anyone who has followed this thread knows, I have made my opinions known and do not accept any credit for the brilliant code assembled by Alex, I only answered a couple challenges by attempting to port his code to build/run under Windows. I am sorry that your opinions of me are so negative. That said, I'm curious if you have experimented and tried to run the "xeon" client for OS-X. The results in doing so with the Windows builds of the code have showna valuable performance boost on nearly all Core2 hosts tested so far. I don't even know if the "xeon" client will run on your Core2 host, thus I pose the question. It might be possible that the code that Alex built is so customized to the Mac that the crew at Lunatics could learn some more if you tried and posted your results. We are all in this project together, aren't we? Cheers, JDWhale |

I missed the original reference that your MAC was OC'd and thus not a close compare with Lovey, my E4500. I would hate to cause you a PITA by offering you to switch to Windows for a test.

Post: Something just occurred to me - since I've got a whole bunch of WU's completed in Leopard I could compare that to the XP client if you want. I know you've got a Harpertown Mac Pro doing SSE4.1 stuff, but if you really want to see if your SSSE3 or SSE3 clients are up to snuff, I think my machine would present a valid comparison. Your host compares fairly closely to my Lovey. Lovey is an E4500 chip running at 2420Mhz 2MB L2 cache at very nearly the same clock... The first comparison between OS-X and WindowsXP clients on the same MacPro has been presented just yesterday, a bit more crunching is in progress to try to fill in the gaps in ARs if possible. [Edit] The X5365 is not Harpertown and has been running the SSSE3 clients.[/edit] Regarding why Mark and I are competing with moderatly OCd Q6600 rigs with "different clients". I believe that we have shown within error tolerance that the "different clients" are very close in performance. (Extensive offline benchmarks have been run that show the clients are within couple percents on the same host). This comparison between Marks HARV and my Thurston is going to show the difference between memory configurations Thurston is running dual channel DDR2-1125MHz, HARV is running single channel DDR2-760. This is a test of how the clients perform on very similar, yet different hardware. The information should be of use to many with similar configurations. For my "nearly stock" Q6600 @ 2520MHz look at Wrongway as he approaches 5000 RAC. No I do not want any more hosts to test on, the picture is already "busy" enough. That being said, If anyone has a Skulltrail that they'd like to run AK_WhalePort trial on, please PM me. Please read that as Skulltrail Only invitation. Regards, JDWhale |

Post: Are there optimizations that have been introduced in the JDwhale & Lunatics versions that Alex could incorporate into an update to his v8 optimized app? In WhalePorting the code, I strived to maintain the original intent and only corrected what the compiler reported as errors. The one exception to this was substituting an Intel IPP function to perform correlation at one point in the code where the original code used a proprietary function to the same end. This change could be incorporated back to an OS-X build as IPP is already extensively used in the original code. Which is "faster", I do not know. Another similar substitution was made in one or two other places. I can not speak to what changes Lunatics have made. From what we've discovered and has been shown in the extensive amount of data collected and presented, your T8300 host might benefit slightly from running the Xeon optimized v-8 client rather than the Core2 client you are currently using. Try it, you might like it ;-) Regards, JDWhale |

Post: A fundamental question that spawned the work that gave rise to this thread was "Is the better performance of Macs purely down to Alex Kan's code or is OSX an inherently better operating system than Winows for crunching?" Thanks to UL1 for being our "guinea pig" and making his 8-core X5365 MacPro available for the trials. Also, thank you to Jason G and the Lunatics for providing us pre-release versions of your clients for comparison runs. And thanks to Fred W for diligently monitoring UL1s host and presenting the results. Though the picture of whether OS-X or Windows is going to be faster now seems unclear, of the results gathered from Windows clients, it is aparent that the Lunatics build is the "hands down" winner on this host. Good work guys, I couldn't have lost this race without you :-( Thanks to all, JDWhale |

Post: I also may convert these Xigmateks to use a mounting plate as the heatsinks are touchy when changing a fan(with the PC off), I was trying to add an air deflector that came with the xigmatek and two of the four plastic pins came up and yep the PC shut down instantly, then I found the heatsinks plastic pins were spread out too much and I had trouble mounting the heatsink until I was able to compress those two pins with some needle nose pliers, DejaVu... You know that I opted to put the KingWin equivalent (to Jokers Xigmatek) model HSF on Thurston a little over a week. I was bumping the OC ~6% and didn't want to pull the mobo to mount the backplate for a Thermatrite Ultra 120 Extreme I had available. To make a long story short, I should have pulled the mobo and used the Thermalrite. This morning I saw the core temps rising, suspended BOINC, then less than 1 minute later heard the pushpin mounts on the top of the KingWin HSF 'pop' loose. I still like the KingWin DHT design & coolong capacity but, like Joker is contemplating, think these models need the backplate for stability/endurance. Three hours later, Thurston has had a "whole body transplant" moved from the Antec P180 case to a CoolerMaster CM 690 case I picked up last week for $50 (clearance rack) when I was in Directron. I really like the flexability of this case, (has a cutout on the mounting tray behind the CPU mount for a fan to cool the mobo from behind), mesh top with twin mounts for fans uo to 120mm, side intake w/fan to feed the HSF with cool 'outside' air. FYI: Lovey moved into the vacated Antec case for now, so she is no longer "naked" ( though she does feel a bit like a "Hermit Crab". Thurston was down for 3 hours beachse after first attempt, I had to re-orient the Thermalrite HSF to point toward the back of the case (different from the HDT KingWin orientation), Lovey went down for 4 hours and is now with the "stock" HSF because of her minimal OC. "Don't worry, man, "She's cool". @Joker - Don't think twice... use a backplate with your Xigmatek HSFs, we've both had problems with the pushpin mounts. I don't know how to mount the fan after the HS is installed, but am sure that you will figure it out and let us know. Regards, JDWhale |

Post: And while I am giving the Penny a little rest, I thought I would do a test run than might interest a few more of you.... This host compares well with Thurston... HARV @ 3420MHz vs. Thurston @ 3375MHz (375x9)... about 1.3% difference in clock. Both are running the SSSE3, Xeon combination of respective ports. @Fred W. & archae86 This should show the benefit of the PGO work that Lunatics has done to gain a few percent over the "verbatim" AK_WhalePort w/o PGO. Hopefully enough data can/has be[en] collected over sufficient ARs this past week on Thurston for a meaningful one-on-one comparison with Marks Lunatics Pre-Release run on HARV. @Mark, what is HARV memory running at? Thurston is @ 1125MHz (375x3). Can you leave running long enough to collect enough data for comparison. I think there would be enough interest to warrant such a comparison. Like you say there are a lot more Q than penryn hosts ATM. Cheers, JDWhale |

Let me gaze into the crystal ball.... 6 Quads (I'll assume Q6600s and running stock 2.4GHz) running the soon to be released Lunatics AK port should combine for RAC ~31200... with draw of ~175W/host = ~1050 Watts.... Sweeeeet! RAC = 29.7/Watt Does that sound like a ballpark figure ? @Andy - Please do get back with the real numbers after the new client is released and RAC have stabilized somewhat. |

Thanks for remembering how similar outages last week hastened Thurston's withdrawl from the "Skulltrail Sprint". After a full nights rest on Thursday, Thurston hit the ground with newfound desire and wisdom to guide him. His cache still has enough WUs to last for a full 3-4 day outage if necessary. We know what can happen when whales are free to move undetected... Be afraid, be very afraid! BOINC... BOINC... BOINC, JDWhale |

Well, the above WU finished, I hit the "Update" button.... I am glad that both my wingmen are running R2.2 flavors and thus overclaimed, making me beneficiary. A closer look at the numbers (CR/Hr) for this WU shows the shift away from the VLAR WUs being in the sweet spot and, with the new AK-v8 Windows ports, now about the same as mid-range ARs of [0.4-0.5] flavor. Let the feast begin!!! BOINC onward thru the fog, JDWhale @David - This WU is on my E4500 running at 2420MHz, I think you can expect similar, maybe slightly lesser numbers on your E6300. |

Post: 600th post @KB7RZF - You can browse Gingers results, I'm switching her between KWSN R2.4-SSE3 and AK_WhalePort V0.2S daily to run same AR WUs on both clients for comparisons and analysis. While this is not going to compare exactly the same as the pending Lunatics release, it should give you a pretty good idea of what to expect. Regards, JDWhale |

Post: Time for a weekly update on all 4 hosts I have running AK_WhalePort v0.2. Yes, it's been two weeks since I posted these charts the first time. The new thumbnails are scaled 30x50% of the fullsize images compared to 30x30% on prior screen caps. Hope this is still not too confusing.

Thus, this chart bears no witness to the WhalePort effect as the others do. I'm really upset about blowing the cache away yesterday, I think this host could have shown the largest relative benefit, judging from what Fred W. has charted so far. Skippers RAC continues upward, though showing signs of leveling off. As one of only two of my hosts which had established RAC history, Skippers chart demonstrates different behavior than most others with their steady ramp upwards. The RAC performance vs. time exhibited here is more typical to what most hosts will exhibit. Who am I trying to fool, they are all going through he roof!

If you've been following Thurstons plight, you know that he suffered a seizure after raising his CPU clock to 3375MHz and memory to 1200MHz. This resulted in Boinc crashing and wiping out his established cache of ~1100WUs. Server and DB problems made recovery of the cache especially when combined with the flood of VHAR WUs, Thurston had back to back days returning 200 WUs each. Since the ~1100 lost during the seizure and the inability to build ample cache to pursue Skulltrail in "high performance' fashion, I made the decision to detatch all WUs and start fresh after giving Thurston the night off. This released the ~1100 WUs to rereleased without them having to "timeout". Well Thurston is back online, cache is now ~580 or about 4-5 days. Will be adding to it in lots of 100 WUs 3-4 times daily until we reach 10 days reserve. Since the Skulltrail hunt, "The Race", is over, I've relaxed scheduling from "extreme" to "agressive" mode. My revised estimated RAC = 7080 Host = Ginger: P4-540 (Prescott H/T) @ 3200MHz I'm not posting a graph for Ginger because she is being switched between R-2.4 SSE3 and AK_WhalePort V0.2S (SSE3) clients as different ARs are downloaded in order to "fill the gaps" in the charts. Couple that her being offline for the past 3 weeks and you can imagine the graph, "steady drop for the past 3 weeks, up the past 4 days" I agree with Fred W. assessment of ~30% improvement in CPU times at mid-range ARs and 15-17% at VHARs. The way I do the switching does not create "hybrid" results, each result is processed entirely using the same client. (Until Murphy steps in and causes power outage or Ginger is restarted during transition from one client to the other.) ============================================== Earlier in this thread I offered up a teaser that I be posting predictions later. My first prediction was that Trevor Immelman will shoot "lights out" 66 and win "The Masters" by 5 strokes. Well I didn't post in time and I would have been wrong on both counts. Next up.... Mac Pros will continue to be the top RAC hosts on the project even after the Windows port of AK client comes public, there is room for one exception that involves overclocking. RAC 10,000 and above will only be seen by the same boxes that are currently capable. The gap will narrow, but the song remains the same. (There might be an exception to this prediction if the owners of the Windows based 8-core rigs can figure out how to feed their hosts without getting bit.) I could very well be wrong here also... time will tell. Sorry for being somewhat cryptic.... NOT!!! Regards, JDWhale |

Ditto here when I remounted Thurston's KINGWIN last night. (Same exact design, easier availability in the US) Only I used a small 6" chisel to press the locks under the fan. Experience allowed me to press down on diagonal mount points at the same time, locked in much better. Are we getting good at this, or what?
Same here fan underneath pointing skyward. The point should me stressed that with these "Direct Touch Heatpipe" heatsinks you are not allowed as much flexability with the mounting orientation, that the heatpipes must "cross the line" of cores as shown on the Arctic Silver mounting instructions. If you don't then the middle heatpipe alone does almost all the cooling. IMO. Installation on a Core2 Duo would require rotating the HSF 1/4 turn so that the fan blows to the front or rear of your case. But we're talking mounting on a Core2 Quad, so be sure the fan points either to the top or bottom of your case. I'm looking forward to a cool front blowing a bit later, so core temps should drop to upper 50s for most the night. Congratulations Joker... you're now as cool as a cucumber!!! |

Even though he had no WUs to crunch I left him powered up as always. So I hit the power switch and was tapping the "delete" key wanting to check BIOS settings before trying to boot him up. I was pleasantly surprised that he hadn't crashed at all, he just put himself to sleep because he was idle and I was only prompted for my password to proceed. First time for everything.

Post: Let me add something to this. I’ve noticed that you’ve been working in collaboration with the fine folks at lunatics so on a more serious note, for helping them in the kitchen to cook this new flavor of soup let me add a personal *Thank You*. You're welcome. Though I am not very active in the Lunatics, I did accept the invitation to join and was "fast tracked" and pointed in the direction of the developers forum there. (My first post was after a night of playing "PaiGow Poker" and drinking Glen Morangie 12 Yr Old Single Malt, just after creating AK_WhalePort v0.1 when I was first "enlightened" to the changes necessary that later became v0.2) Some discussion in the public forums, some PM exchanges on ideas, information sharing, and some benchmarking of their clients when I can be of help. Other than that I have kept my finger out of the pot. You know what they say about "too many cooks" ;-) In programming there is almost always more than one way to do a task, and style for code, once set, should be followed to maintain readability and maintainability. Though I haven't seen any code other than Alex' original tarball and my own port of that code, I am almost positive that the forthcoming Lunatics port will be both more readable and maintainable than either I have seen. Cheers, JDWhale [edit] @Joker - Let the hunt begin... Tho "The Race" is over, Thurston is back online and "doin' fine"... Temps have dropped after reseating the new HSF again last night (66-65-60-62). @John Neale - I've been a Trevor Immelman fan since his first Masters appearance and Gary Player is pure class. @Fred W - It's not polite to talk about the weight of a whale.

You are not alone, and the patience being exhibited by the posters to this thread is amazing. Not everyone is the business/profession of software development and sometimes it's difficult for "outsiders" to understand why public release of a software product takes so long. I might not have made it any easier with my public exploits and "over the top" claims. I'm comfortable that the public release is in good hands with the Lunatics crew and that they are dotting all the 'i's and crossing all the 't's and preparing clients for as many configurations as possible. All this takes time... lots of time. Couple this with the required testing on those configurations and the whole effort is volunteer by real people with real jobs who need to find some time for family and golf (remember it is "Masters" week ;-). I'm sure that most everyone knows all this, after all we are enthusiasts when in comes making our hosts, our personal computers, our computing farms perform to their best. ======================================================================= Brief history for anybody just joining the party/thread... As it was stated about 4 weeks ago in a thread far, far away that the task of porting Alex v-8 code was not easy, "if you think it is , DO IT!". Three days later, I had, and this thread was born. Thread readers became aware that an organized effort was already in progress, colaboration follows, Las Vegas break for R&R, research followed by enlightenment gets the Alex optimized GAUSSIAN code working using Intel IPP replacement function, more colaboration, testing, more optimizations (nicknamed "Xeon") discovered, more testing, more colaboration. Development has been at breakneck speed and my side of it is all posted in this thread as well as: "The Race", charts, plots, opinions, analysis, new clients for SSE3 hosts, more charts & plots and the personal graphs from my own hosts that have switched to running my "prototype port", AK_WhalePort. Pardon me for being self promoting, but if you haven't followed this thread from the beginning, you've missed a pretty good story in the making. All of us in the same boat, extremely favorable comments from some of the leading Mac Pro owners who have ruled the "Top Hosts" list for the past 6 months, no flames, just cooperation by the folks doing the work and words of support from those on the sidelines. As said, patience my friend, and enjoy being privy to seeing some of the tasks necessary doing development in preparation of a release and knowing the release will be the best it can be. Just my opinion, JDWhale |

Post: Do you Hyperthread? As mentioned a day or two ago, I've brought back the lovely Ginger (hostid=2166150) for an encore performance. Ginger is a 3.2 Ghz Prescott with 1.5GB DDR-400 in the form of a Gateway 508GE.. Ginger has been crunching since about 9 Apr 2008 13:00:00 UTC to set a very sparse baseline using: Optimizers: Ben Herndon, Josef Segur, Alex Kan, Simon Zadra
Version: Windows SSE3 32-bit based on seti V5.15 'Ni!'
Rev: (R-2.4|xP|FFT:IPP_SSE3|Ben-Joe)
CPUID: 'Intel P4 Pentium-IV (Prescott)'
cpus: 1 cores: 1 threads: 2 cache: L1=16K L2=1024K L3=0K
features: mmx sse sse2 sse3
speed: 3200 MHz -- read megs/sec: L1=4802, L2=4384, RAM=3303
A couple hours ago I introduced Ginger to AK_WhalePort V0.2S (For SSE3 capable hosts) and the results are trickling in. A few VHARs on short order with a limited assortment of ARs to follow until she runs out of work. I plan to keep Ginger up and crunching for about 1 week, switching between clients as/if varying ARs become available. Three VHARs have reported, CPU times range from 2400-3300 seconds for AK_WhalePort depending whether run concurrently or against mixed AR WUs. This compares to CPU times ranging from 2900-3800 seconds under similar conditions using the the baseline client. My initial view for VHAR WUs on this host is a 13-17% reduction in CPU times when running AK_WhalePort V0.2S vs. the competition. Anyway, the reason for running this test is to demonstrate possible benefit of Prescott hosts switching to the ported AK client when available. I'll leave further data presentation and analysis to others. Regards, JDWhale |

Post: All, Well I've been privy to some early numbers and must apologize for my rant of hours past. Though Thurstons WU processing rate was quite high with the maelstrom of VHAR distribution over the past 48 hours, he was still very short of being able to crunch and return his download limit of 400 WU/day. In fact WinterKnight made the accurate assessment of reading Thurstons (and my) situation of being a "new" host trying to build a cache while being flooded with the VHARs. No Thurston is not a new host, just rebuilding his cache like a new host. There were not any of the said "errors", but there were 2 "user aborts" due to BOINC 4.45 client as wingman, and pretty fast turn around. @WinterKnight - I'm sorry for coming off brash. I'll try to keep my passion in check and the "cork in the bottle" after midnight, while awaiting the time that I can push the button to get more work. Humbly yours, JDWhale [edit] I just noticed that Wrongway, the other Q6600, has worked her cache to less than 12 hours, ~30 WUs, after dealing with the same VHAR attack, I hope we can get more work soon.

Post: VHAR's over a few days only make up about 30% of all units issued, and even with the hopefully new further optimised apps the 63 and 50cr units are still going to take an hour or so to crunch. The chances that a host can crunch more than 100/cpu in any one day is almost nil, and for longer periods is worse odds than winning the lottery. Can we wait to see some quantitative numbers before make generalizations about the possibilities of the new clients ability to push the envelope. True for the "Average Joe" this does not become an issue, hopefully over the past few weeks I have shown that I am not not that "Average Joe" and tend to push the limits when it comes to computing. Until now, I have only used BOINCs scheduling methods, today I employed my "extreme scheduling methods" in order to maximize computing efficiency and have discovered that the project is not able to deliver ample workload to maintain maximum thoughput on my host with the new optimized client. Do I think I hit the "magic number" of 400 returned results within that 24 hour period? I answer NO, maybe 60-75% of that number, but I think I returned enough results that my quota should be raised for that period. Can we please wait to see some numbers? The point remains, IMO, if a host can return 200-300 valid results and it's cache has room, then the quota should be the "fixed limit" of 400 + the number of valid results. In a time that the project is in need of computing resources, why would you want to throttle back on the largest contributors? My CPU is "only" a Q6600 running with an agressive, but not extreme, 3375MHz OC there are much faster 4-core rigs whose owners are watering at the mouth to run the same client I am running, let alone the potentially faster client about to be released. IMO, this problem will not go away if ignored and needs to be addressed before the new optimized client is released. We are talking about enforcing limits on the enthusiasts of this project, that is not a good idea. Comments welcome, JDWhale P.S It's now 1:47AM in my time zone, only 13 more minutes until I can push the "Update" button and try to build Thurstons cache. I hope that I can grow his cache and am not stuck in the same position 24 hours from now. |

Post: JD it says you have 2038 work units in your cache ~1100 got abandoned ~55 hours ago when BOINC crashed and emptied the cache. It's documented in this thread. I've asked for help on how to detatch those 1100 WUs, none was offered. Thurston has ~460 WUs in his cache right now, the other ~500 have been returned and are in various states between waiting to be validated and waiting to be being purged. Extra stress on the project servers over the past 2 days DB issues are probably not helping. |

On the brighter side, Thurston did manage to recover ~200 RAC from the low right after the DB server came back online. Thurston is facing a bit of another challenge right now. The project is refusing to serve us any new WUs for another 6-7 hours, says that he has reached his daily quota of 400 WUs..... Problem is that Thurston only has 475 WU's in his cache, those darn VHARs that Berkeley has been serving up are causing us problems. Thurston turns these around at a rate of ~4.5/hour per core (roughly 432 WUs/day) more than his "quota". We'll wait to see the numbers if one of our wonderful chartists can capture it. (I don't know if I'm making an impossible request, just asking ;-) Is there any to quantify the number of WUs returned in a 24 hour period? I'm curious if he returned more than his quota of WU's. How can you win a race when you are not supplied enough fuel? Quotas need to be revisited as the throughput of hosts jumps to another level as demonstrated with this host today!

Post: To satisfy my personal curiousity, partly fuelled by Skippers surprising performance on AK_WhalePort, I have decided to bring Ginger back for a brief trial of the ported clients. This is a P4 Hyperthread host with SSE3. Commencing 12:15 UDT 09 APR First up she will be running SSE3 R-2.4 Her stderr looks like this: [color=blue]Optimizers: Ben Herndon, Josef Segur, Alex Kan, Simon Zadra
Version: Windows SSE3 32-bit based on seti V5.15 'Ni!'
Rev: (R-2.4|xP|FFT:IPP_SSE3|Ben-Joe)
CPUID: 'Intel P4 Pentium-IV (Prescott)'
cpus: 1 cores: 1 threads: 2 cache: L1=16K L2=1024K L3=0K
features: mmx sse sse2 sse3
speed: 3200 MHz -- read megs/sec: L1=4349, L2=4040, RAM=3190
[/color]After establishing herself with a bit of history, I'll switch her to AK_WhalePort V0.2S (SSE3 client) for comparison. FYI : Ginger is a Gateway 508GE 3.2 GHz running stock except for 1 GB memory upgrade. Ginger_CPU-Z.jpg Ginger_CPU-Z_Mem.jpg Cheers, [edit] fix bbcode url @David - headers look fine here. [/edit] |

This WU is about the closest I can find to the one we shared. You should be glad Thurston was a no show and forfeited the match. You can be a hero to your kids instead of them having to carry you home after the massacre. (~44%) If our hosts should actually meet up soon, Thurston will not be so nice. |

Additionally, after installing I will lay Thurston on his side to allow gravity to help the heatpipes perform slightly better. Thanks for that excellent review!!! It confirms that we're both making very good decisions. You and I will have twin HSFs from different mothers. |

Thanks for reminding me, I'm putting the order in at Directron for the Revolution RVT-12025 now. $32.50 (tax included) and only 10 miles from where I live. I can pick up in the morning. I've got the Thermalright Ultra 120 Extreme here, and will use on the next system build, I just can't afford the extra downtime to pull Thurstons MoBo to install the backplate right now. I think the SKT master's been lurking and is onto the plan(sudden rise in RAC the past 4-5 days). The 92mm version works great, (remember Lovey was wearing it in the "PC Chick" centerfold last month), but we're hitting 85F these days and with the raised OC, it's just not enough for a Q6600, (sitting at 69-65-63-69 as I write). I don't like to run the AC until we get upwards of 95F. Ambient in the computer room is 26c right now and headed higher (~30c) tomorrow. Thanks, JDWhale |

Post: Host = Thurston: Q6600 @ 3200MHz (for now)  JDWhale wrote: My estimated RAC = ~7400 From the looks of the Thurstons daily graph, Murphy must have paid us a visit today. Still do not know what happened, other than maybe the memory boost to DDR2-1200 was a little agressive. Thurston did not BSOD, one minute tearing through the first set set of WUs, three were going to be hybrids between his old clock and his new OC. The next minute BOINC had come tumbling down, system still up, just no BOINC. And no more cache of WUs. That quick and without warning. Backed off the memory a pinch by reducing multiplier from 3.2 to 3, bumped up vCore a tad, ran some more tests and went live. Here's CPU-Z caps of CPU and Memory tabs: Thurston_CPU-Z.jpg Thurston_CPU-Z_Mem.jpg Though some might consider todays loss of ground as just short of distasterous, I'll offer up a glimmer of hope: Thurston only lost ~2 hours of production, he has lost more than that in one day running benchmarks. His new diet, while not the leanest is tailored to get him back on into this race very, very quickly. I'm providing support and trying to keep him focused on the primary target. I think that within 24 hours we'll be able to see the recovery tactics in full stride. Just because you suffer a flat tire, doesn't mean you will lose the Tour d France, maybe no yellow shirt for that day, but far from losing the race. I've got to get back to work, afraid we're working into the wee hours tuning things up for a mad dash beginning tomorrow. Live long and BOINC even longer, JDWhale |

Post: The operation seems to have been a success in the end, but not without casualties. BOINC crashed and seems to have wiped out Thurstons cache of ~1100 WUs. They are nowhere to be found on the host, and still show as "Scarecrow" (out in the field, LOL). Detatch was not a selectable option. I am afraid that I have abandoned my wingman, gone AWOL. I am sorry. Thurston has gone back to live production and is gaining confidence with his newfound speed. Will post CPU-Z screen caps with nightly RAC graph. While this might be considered paramount to admitting defeat in the SKT hunt, do not count Thurston out just yet. Remember Skipper lost his cache in a different, but equally painful manner at the time of switchover to the AK_WhalePort V0.2S (SSE3) client and never missed a beat. FYI: I am willing to refund your pending credits, Please send a self addressed stamped envelope and $5 restocking fee and I will issue you an "IOU" for the abandoned credits. @David - Sorry but This WU was amongst the casualties. Please accept my sympathy for your loss. Yours in mourning, JDWhale Anyone have an idea how I can release my association with the now lost WU's |

Yep, just had a look and This WU is still about 360 WUs from what Thurston is crunching at the moment. You should see result validated by early Wednesday, my time not yours. (Just a stab at a target based on ~130 WU's in Fred Ws 0.400 - 0.50 : 78% bin) Though this is in some of the lower performing in Credit/hour ranges, at least it is reassuring that Thurstons getting through them nearly twice as fast as before. Due to Thurstons current diet (so to speak) I do not expect his RAC to rise much on the next 24 hours without a little bionic adjustment to compensate for the lack of carbs. "Better, Stronger, Faster" "We have the technology" "Thurston is that Whale" Better BOINCing with bionics, JDWhale (now scrubbing in and putting on surgical mask) @Fred - thanks for the updated charts and bin statistical data. |

Post: [Here is a linear scale plot showing the one region with data from both aps. Thank you for sharing, I should have alerted a few, like you, of Thurstons hostid earlier, but felt that the other hosts provided enough exposure to validate my experiment. Coupled with my switching Thurston to v0.2 within 24 hours of returning from Las Vegas, I don't know how much more data could have been collected. I'm thankful that Wrongway had 5 days of crunching that were captured and is still running without any hardware variation, this makes him a much better example for documenting the switchover on Q6600 hosts. That tight grouping is beautiful, it demonstrates that regardless the WUs crunching the CPU times are predictable. I'm thinking that this will lead to more consistant host RAC with less dramatic variations, especially when coupled with the much more efficient crunching of WUs with AR {0.4<=XXX<=1.25}. If Thurston can fetch some more VHAR WUs, I'd like to try running him so that he crunches 3 VHARs and one other WU to try to gain insight of the "mixed WU behaviors" on multi core hosts with this new optimized client/application. The whisky is starting to kick in, Does any of that make sense? Cheers, JDWhale |

Post: Time for a weekly update on all 4 hosts I have running AK_WhalePort v0.2. Yes, it's been a full week since I posted these charts the first time, Sorry, but I've grew the image sizes just a bit because of the large change in vertical range. The new thumbnails are scaled 30x50% of the fullsize images compared to 30x30% on the original screen caps. Hope this is not too confusing. Host = Skipper: P4D-820 @ 2800MHz JDWhale on Mar 30 wrote: Lastly we see P4D-820 SSE3 chart, note it's very erratic and with it's just losing its 10 day cache will probably remain that way as Pending Credits will be rising. Thus, this chart bears no witness to the WhalePort effect as the others do. I'm really upset about blowing the cache away yesterday, I think this host could have shown the largest relative benefit, judging from what Fred W. has charted so far. Last week Skipper was last in the line, but this week he is first in the lineup. Well Skipper surprised me, by not even seeming to notice that he didn't have a built cache. Looks like SSE3 dual cores will also benefit immensely from a switch to ported AK code when available. Makes me wish that I didn't decommission my 3200MHz Prescott two weeks ago, I might have to bring back Ginger for an encore engagement of one week to checkout her hyperthreading with the SSE3 version of the build.

Well Thurston is unhidden, and I haven't had to try "extremely creative scheduling" yet, though I left the gate open last night and quite a few very sweet WUs got away before I could crunch them... or something like that. Actually, what happened was that I accidentally allowed his cache to fill to 10 days. I've been keeping his cache ~6 days, only downloading enough WUs to run for 24 hours at a time. This allows me to get a sampling from the WUs being offered up every day rather than overloading on just one days offering. Make sense in some sort of twisted way? I hope so. My estimated RAC = ~7400 Whatever it takes to catch Mr. Skulltrail....(no taunting intended) Congratulations Fred W., You must have read my mind ;-) This effort means that Thurstons bionics need some tweaking, I'll start my boosting the CPU to ~3300MHz and re-evaluate after some WUs post.

Like I said, "I'm not aware".... I was careful to keep Thurston undercover as best I could, but when you are growing 3 inches per day it's not too long before you stand out in a crowd. I hope you got in early enough to collect some 2.4V samples for comparison. I'll tell you when I decide uptick Thurstons OC for that last minute pedal to the metal, push to the end, win by a nose, photo finish. (IFF needed ;-) My guess that UTC time with the results buffer flushed will be enough information for you to make necessary DataVac adjustment, or should I tweak the version in stderr a bit just for certainty? -JDWhale =========================================================================== Oops seems I've over ran my original post..... Here's my quick thoughts why my adjusting Thurstons OC is acceptable.... Thurston started running AK_WhalePort v0.2X just one week ago yesterday (I think. It's been a busy week, but the app is dated 3/30, so I think 8 days is fairly close). To accurately settle on RAC can take several weeks, depending on wingmen delays, WU diet, extraneous computer usage, etc. My fiddling with Thurstons clock in the last couple days of this 16 day race is just my way to help him reach what might actually his true RAC. Who knows? (What he knows, we don't know. Exactly!). I'll try to remember to post a CPU-Z screen cap. Up for discussion and time for those last minute guesses on just what Thurstons RAC will be come April 15. I'll post my prediction for all 4 of my hosts running AK_WhalePort v0.2 when I post daily the RAC chart in about 2 hours. Current guesses are JokerCPoC 13,000 David 6,740 Pilot 5,880 msattler It already hurts........ The Curmudgeon 6,000 +/- 250 UL1 7,000 Fred W Wh*? Interesting....

Post:  Host = Thurston: Q6600Walter Winchell used to open his broadcast with: "Hello Mr. and Mrs. America and all the ships at sea." I'm sorry, but that phrase holds a bit of nostalgia for me... though born in 1958, it was probably a bit before my time. So was Humphrey Bogart, and he is one of my all-time favorite actors. Too bad he had to keep up the "macho smoking image" on screen. I digress. Thurston fell a bit short of my predictions for today. Yep, he ran ~2 hours of "uncredited" benchmarks last night, and equally as much today plus a little "AK_WhalePort v0.3" work on the side. I make no excuses, but as stated much earlier in this thread, Thurston is not a dedicated S@H cruncher. He is my "desktop" system and does much more than crunch WUs. So here it is, midnight in my time-zone and Thurston sits at #31 in the "Top Hosts" list, just 50 RAC below my prediction of 24+ hours ago. Put your seat belts on folks, in less than 24 hours I will update my prediction for Thurstons RAC to be reached in ~10 days or less. The number is no longer 6500! Guesses welcome...

Remember back before your trip to Sydney to get the Thermalrite? We exchanged a few messages about memory...I went with BALLISTIX DDR2-1066 about a month ago.

But his cerebral cortex survived. "Gentlemen, we can rebuild him. We have the technology", they said. "We have the capability to build the world's first bionic whale. Thurston will be that whale. Better than he was before. Better, stronger, faster." The rest is history being documented in this thread ;-) Sorry, I'm still hungover from quenching my thurst[on] during the all night coding session and 2 hours sleep, tend to ramble on and fantasize a bit when I'm hungover and delirious. Anyway, the memory is running "stock" with VDIMM set at 2.2V... Mind you with this memory "stock" is overclocked, so they say. Works out with perfect 3.0 multiplier at this bus speed.

Yep, Orca sounds nice, and they might be prettier to look at, but I am of the more intelligent Humpback species of whales. Hunted to the brink of extinction, now on the comeback trail. In seriousness, AK_WhalePort will not see public release, but is seeing service as a 'testbench' for some of my new ideas. AK_WhalePort is also the vehicle I'm employing to slap the kitties silly in about a weeks time and takedown the Skulltrail.

Post:  Host = Thurston: Q6600Tough day it seems for Thurston, while most of the WUs crunched from deep in the cache validated, his diet in the past last 24 hours included a large side order of VHARs which are still awaiting Berkeley to validate. Thurston appears to be gaining a bit on his wingmen, probably need to try to grow the cache a little closer to what the Frozen Penny has, I'd hate to be waiting for wingmen to post as this race nears the finish line.  Host = Skipper: P4D-820Thought an update on P4D-820 SSE3 progress was due. ~10% gain in RAC since starting on AK_WhalePort v0.2 SSE3 5 days ago, even with losing his 10 day cache at the transition point. Live long and BOINC often, JDWhale [edit] Make text links point to host rather than chart. [/edit] |

Hate to admit it, but tonight is going to filled with tension and might explain my "possum like" behavior.... A bit over 3 weeks ago, on March 8, THURSTON reached #48 on this same list, I've posted his local RAC chart and will do so again after todays close, Thurstons RAC on that "ill-fated" night was 4369. Then along comes the WU from ehll, forcing the BSOD and subsequent thrashing of a MoBo that just won't POST. That fiery WU not only took out Thurston MoBo, but also fried his memory. It was the same memory that was in the mighty E4500 host (Lovey) when this thread started and would cause Lovey to lock up every 7-8 hours. The same memory that crunched the first WU with the original AK_WhalePort that started all this hoopla. A couple days ago I put the RMAd replacement memory back into Thurston, Crucial BALLISTIX DDR2-1066, bumped the voltage up to 2.2V, bumped AK_WhalePort from V0.2C (Core2) to V0.2X (Xeon). We come full circle. Though this time around Thurston is running at a much more modest 3200Mhz rather than the 3600MHz and His memory has slowed from DDR2-1200MHz, He is making his run with AK_WhalePort and not skipping one single beat. But my spine is tingling as I observe with a sense of deja vu. (Or like one of my favourite all-time baseball players has said, "It's DejaVu all over again". Yogi Berra) So in the past 3 weeks the RAC for the same position (#48) on the "Top Hosts" list has changed by ~500. And here we sit, on the same rung of the ladder, only a little bit higher in the air. Again we come full circle. Yep, tonight I'm a bit scared, thus I'm just a whale in waiting, "playing possum" so to say. Hoping that tonight we break from the full circle and break out instead. BOINC onward though the fog, JDWhale [edit] I just realized that the performance boost being seen with v0.2X might be related to the memory speed going from DDR2-800 to DDR2-1066. After todays close at 24:00 UDT, I'll switch back to v0.2C and recheck the numbers. You can check the results yourself, the AK_WhalePort version is displayed in stderr. [/edit] [edit2] On the other hand hosts Wrongway(Whale2) & Lovey(Whale1) have not been shut down in more than 2 weeks and shows similar benefits as Thurston when running V0.2X over v0.2C After all, I will not be converting Thurston to v0.2C at 24:00 UDT and will continue running v0.2X. Addin that I ran v0.2C last night for a few WUs and the results agree with the charts, V0.2X is ~8% faster than V0.2C in the mid-angle WUs. [/edit2] |

Post: i have a e8400 .. need another tester ?? So while Penny is "testing" the new port live, gaining ground on Thurston, I've scaled Thurston back to 2.4V trying to fill in the VHAR hole in the performance charts for comparison (while I've got the VHAR WUs available.) Dang nab it, I might never catch you at this rate :-( But who?s Skulltrail might be within reach even if you aren't... I'd rather bag an 8-core OCd X9775 than a 4-core X9650 anyway.

I make no excuses and have no desire to make it so. Most my past experience has been in the R&D environment where standards are lax and we always have passed our code to those than can make it meet standards, release it, and support it. Rapid prototyping, proof of concepts, hotfixes, and such is a totally different type of coding than a lasting, maintainable project like this must have. I hate neat code, because I don't want to write it. You know how is with some folks, nobody else can read their handwriting. That is the way I code, it's not very readable.

Post: Before someone accuses me of being a CPCW, I admit it. I've just cancelled a WU where my wingman was running BOINC 4.25... Here it is wuid=240743754 I've been running Benchmarks on one of Thurstons cores about 8 hours today with about another hour to go before I can get back to crunching 4 cores. Please excuse me if I don't want to accept "under credit" for one WU while trying to chase down a host running at nearly half again Thurstons clock. Add in that he is running Alex Ported in short bursts. Sure, Mark will tell you that he is running benchmarks too, that he is suffering the same as I. But "Frozen Penny" runs the benchmarks much faster than "Thurston" can and gets back to crunching before him. @Mark - Thurston's got Penny in his sites Buddy, she can run[WUs really, really fast], but she can't hide!!!! LOL..... BOINC On..On... JDWhale [Edit] Thank you to all... We're all in the same boat, wanting to meet the project crunching demands one way or another. I'm just glad I could contribute in some way and can't wait to see the first host with RAC 20,000 as a result. It might not be long and there is good chance it will belong to... you know Who?, We will see Skulltrail at it's finest if he opts to run Alex code.

Post: Though Fred can provide more widespread analysis and total assessment... A quick peak at the 0.39 AR 72.23 credit WUs that we're both choking on right now shows me that Thurston ~16% faster than your Penny at this AR. Of course you're running at 4000Mhz and Thurston is only at 3200Mhz, so the comparison is not at all fair ;-) Mind you that neither Mark nor I are running Chicken+ (sorry if this is not the preferred moniker). Mark might run it for short bursts for benchmarking. I'm running WhalePort v0.2 and am holding nothing back and disclosing everything I've learned and done with the crew working on the Chicken+ port. As said before, I'm restricted by Intel from sharing WhalePort, but I do not want my short-term effort to be lost. I hate to reitterate that point, please understand my position. By "already optimized", I assume you're referring to the earlier Lunatics KWSN, Cruncher built 2.4V version. While it's true, that code was/is "optimized" and demonstrates a remarkable performance over the "stock" app. The source code in "Alex Kan src-v8.tar" is a total rewrite of several functions that highly leverage the SIMD instruction sets on more than one level (SSE2 SSE3 SSSE3), addin differenly coded algorithms based on processor characteristics and you can see that the code is complex and lends itself to many possible permutations. Give those folks doing all the work at Chicken+ the credit they deserve, That is where your "ported" app will likely come from. I'm just a big mouthed fish that got lucky with some "trial development tools". IMO...At first & second look, some functions bear absolutely no resembelance to each other. The methods of optimization are beyond my comprehension, I have no working knowledge of SIMD instructions and often find myself laboring over just a few lines of code trying to understand the method. This isn't the stuff you're likely to learn at school without at least a half dozen prerequisites, more likely only after already in the workplace a while and paying Intel dearly for a customized course/workshop. Just my opinion, YMMV. I don't pretend to be a coding expert and fall far short on Windows code (my working knowledge is in low level 2D Graphics, 3D-Graphics(OpenGL) and performance computing on the SGI Shared Memory MultiProcessor super computers of yesteryear. Like I've stated before, "Kudos to the folks that understand & develop this stuff". I'm just a porter that prefers hitting golf balls. I think I'll head to the practice range now. Cheers, John |

I'm counting on you running 2.4V as the only way Thurston could even come close to catching Penny. Remember that Thurston is only a 3.2GHz Q6600 chasing your 4.58GHz X9650 Extreme... You've got almost 1.5 times the clock rate and 1.5 times the L2 cache. I estimate that my WhalePort of AK code is ~1.6 times the speed of the 2.4V code... This might prove an interresting challenge ;-) I estimate that if Penny were running the ported code full time that she just might reach RAC of 10,000. I wouldn't stand a chance in ehll of once the "Chicken Plus" port comes public... So a little friendly "exhibition match" to demonstrate ported potential for us "little Q6600 guys" in the mean time.... I might be substituting in other "minor tweaks" to help gain advantage if I can find some, so watch your back, Penny ;-) Cheers, JDWhale |

Post: The 4 simultaneous VHAR WUs on Whale2 completed and posted. I'm happy to report only ~10% performance hit from running them one at a time on that particular host. Much less impact than running 2 simultaneous on Whale1 where the performance drop was closer to 70%. I am leaning to the smaller L2 cache per core being the culprit since Whale1 is actually running faster memory on a newer[better?] chipset and only feeding 2 cores. Whale1: Gigabyte GA-P35-DS3L & E4500 @ 2420MHz & DDR2-800 Whale2: Asus P5B-MX & Q6600 @ 2520MHz & DDR2-800 (though MoBo limited DDR2-667)I know the MoBo & CPUs are mismatched, catastrophic events of 8 March, remember? "WinterKnight" wrote:
In your case as with archae86 the issue might be more bandwith related as you're trying to feed 4 cores vs. 2 cores. I'm thinking that this "memory bottleneck" will likely disappear with the enhanced use of SIMD instructions offered up by Alex. Of course many H/W variables also come into play as we're seeing with Whale1 and it's limited L2 cache cause it's own issues. We are really seeing that all clock speeds are not created equal, even within the Allendale/Conroe chips. Of course, I might not have a clue since I'm really more of a coding hack than a hardware expert. What can I say, "Opinions are cheap" ;-) "David" wrote:
'Tis a bit funny that you raise that point.

I do hope to get back to the original intent some day soon, though since I'm only interrested in running S@H, any changes I make to Boinc scheduling code will likely have limited practical value away from S@H, thus will probably remain private :-( We'll see, I haven't had a chance to "look" into the Boinc code yet, beyond building it that is.

Post: archae86 wrote: The updated Whale1 and Whale2 graphs now include a useful amount of results near Angle Range 2.35. They also have a very clear different in scatter, with the E4500 results much more varied in CPU time at a given Angle Range than the Q6600. Thanks archae86, for collecting the data and generating the scatter plots. I've got a comment to make about the variation in CPU times being witnessed, especially pertaining to VHAR WUs on Whale1. I am scheduling these VHAR WUs to run one at a time vs. WUs of other ARs, there was one instance when I purposely ran two of these WUs concurrently, this can be seen when the CPU times came in near 1800sec vs. the 1000-1250sec when run one at a time. We know from past experience that the E4500 chip with it's 1MB L2 cache per core causes a severe performance penalty when these WUs run concurrently. Since these WUs typically come in bunches and often run concurrently at "high priority" due to the shortened deadlines, the data in the graph might be a bit misleading from what your "typical" user can expect. I'm controling Whale2 similarly, but have not allowed more than one to run at a time yet. That is going to change right now. I'm kicking off 4 VHAR WUs to run at the same time, so when the next datas are presented we should see some data points at the "worst case" location for the Q6600 Whale2. I do not expect as much variation as Whale1, but we should be able to see some variation from the 1050sec seen in the current plot. I'm sorry if by controlling what WUs are free to crunch at any given time is not entirely up to the BOINC scheduler, but I feel that I can get better throughput by taking some control to prevent known bottlenecks and raise overall performance. So, am I manipulating the data? Maybe yes, but I'm at least telling you about it, and why. Finally, here is the new graph for the Smithfield host, for which I certainly concur that this version of the port is showing a very nice speedup. <img snipped> To help fill in the blanks, I've just set Whale3 back to running KWSN_2.4_SSE3-Intel-P4_MB while there is some variation of ARs in the queue. This should help to paint the overall picture a bit better. I won't let it go for very long, just long enough to get some more data points for comparison. Regards, JDWhale |

Her MoBo was donated to Thurston when his failed, while her processor is mounted to Wrongway. and the new Lovey was born from the spare parts bin and has since gone thru a number of operations, but she is still naked and likely to become a quad soon (Frys has the Q6600 for $190 in some parts of the country.)

Post: So, I'm running WhalePort v0.2 on 4 hosts now, 2 x q6600, 1 x e4500, 1 x p4D-820 I like the charts that Fred W. & plots that archae86 have been posting so much I thought I'd give it a personal touch and tell you a little story of what's in the works for the next 2 weeks. All you with the bigger and faster quads & octos will have your day soon enough, I hope that you don't mind if I get the jump on you and share my experience. One common factor affects my Core2 hosts depicted below. On Mar 08 I suffered MoBo failure. Probably pushing the box a bit too hard. Q6600 running at ~3600MHz (405x9) with DDR-1066 memory pushed to ~1200MHz. Then along the "firebreathing" WU from ehll and took out the MoBo (that's my story and I'm sticking to it, Pilot is my corroborator, check the NC board about that time, you'll see ;-) Next morning was the MoBo/CPU shuffle, thus the behavior changes evident in the charts at that time. Hosts changed names, WU's were ghosted and detatched, clock rates changed, etc...I won't bore you with all the details, but the charts bear witness to the changes in host configurations. Host = Lovey: E4500This is the mighty E4500 @ 2420Mhz left running WhalePort v0.1 while I was in Las Vegas Mar 23-27 and switched to v0.2 on Mar 28 Host = Wrongway: Q6600This host is Q6600 @ 2520MHz switched from SSSE3 R2.4V to WhalePort v0.2 on Mar 28 Host = Thurston: Q6600This host is Q6600 @ 3200MHz I guess it didn't report results on Mar 27 explaining the deep V before switching to WhalePort v0.2 on Mar 28. This is the host that I have hopes for reaching RAC ~6500 before the next 2 weeks, be warned that I might employ "creative schedueling" if necessary. I will be unhiding hosts as it approaches being the top Q6600 in the "Top Hosts" list in the next couple days, though I'm sure that you can find it in the "Top Hosts" list if you look hard enough. It is also the host that I do development, testing, benchmarking, and browsing on and am using now to compose this message, so I don't feel too guilty about employing that "creative schedueling" to level the playing field a bit. No, I will not be cancelling results for this run to the top, just some results might stray a bit from the default processing order. It's out in the open, I'm telling what I'm going to do, you be the judge. Host = Skipper: P4D-820Lastly we see P4D-820 SSE3 chart, note it's very erratic and with it's just losing its 10 day cache will probably remain that way as Pending Credits will be rising. Thus, this chart bears no witness to the WhalePort effect as the others do. I'm really upset about blowing the cache away yesterday, I think this host could have shown the largest relative benefit, judging from what Fred W. has charted so far. Anyone guess the theme of my LAN/Workgroup ? Kind regards, JDWhale |

Maybe... "Speed Limits" could/should be imposed. In the sake of "fairness" for all... NOT!!! ( though it might save more than a few MoBos from going up in smoke ;-) ============================= I don't know if it's been mentioned yet, but IIRC there is another optimization level, in at least one part of the code, for XEON processors, above and beyond the SSSE3/CORE2 stuff I've focused upon to date. Because I do not have the hardware to test on, and due to license restrictions, can not redistribute, I do not know what other performance benefits Alex has coded for the "high end" chips. In this regard, it's possible that the Mac Pro still has an Ace in the hole with regard to the WhalePort. Regards, JDWhale |

Glad to hear that I'm not the only one losing sleep... That whole week before holiday, from the day this thread started, I was getting by on ~2 hours sleep a night. I kept telling myself that I was in "training" for the Vegas scene ;-) Truth be told, I had to go to Las Vegas just to get some rest. Try telling that one to the folks you're gambling with at 3:00AM. I had to resort to "catnaps" in the afternoons just to keep alert at the tables. While driving up into Death Valley, I pulled onto the shoulder just to fit in a 45 minute nap when I felt myself nodding at the wheel. Don't know if you pulled an all-nighter last night or not, but at least I got a couple hours sleep while you were running benchmarks early this morning. Keep with it Mark, you know the saying...

Post: Good Job guy's........... I too, was curious about that, but am happy to report the same temps as when running SSSE3 V2.4V on Q6600. Q6600 running at 3200MHz (9x356)... CoreTemp reports 63-57-57-61 with room temp at 26C. HSF is KingWIN Revolution RVT-9225 in Antec P190 case. Note HSF is rotated 90 degrees so that the fan blows toward the top of the case... this aligns the "Heatpipes" perpendicular to the bead of AS5 and cools much better than when fan is pointed toward the back of the case. Not a problem with the Antec P180 which has exhaust fans both on top and on rear. HTH and YMMV, JDWhale |

Post: Very nice presentation Fred. I would not expect any performance improvement on VHAR WUs, I'm understanding that there is no Gaussian search performed on those WUs. The main (only?) difference between v0.1 and v0.2 was to turn on the part of Alex code that implements vectorized gaussian detection (I don't mean to sound smart, I'm just reading the comments/descriptions in the code. For all I know that part of the code walks your dog for you ;-). The vectorized gaussian code seems to knock ~20 minutes off the CPU times for Intel Core2 hosts running at ~2.4GHz over the non-vectorized code regardless of AR. Thus we see the 1200 second step between v0.1 and v0.2 for the ARs presenting so far. It's been documented that I ran out of time before leaving on holiday to debug this part of the code, thus the intermediate (v0.1) version. It's interresting to see how improvements in different parts of the code impact run times. ================================================================= On another note, my Smithfield has posted enough results to be included for those that will benefit from SSE3 capabilities... hostid=2938512&offset=60 is showing similar performance gains as already presented for the SSSE3 capable chips. This host is a Dell XPS400 running a P4D at 2.8GHz. (~30% faster than KWSN_2.4_SSE3-Intel-P4_MB) This is my HTPC hooked up to a HiDef front projector and Dolby digital 5.1 receiver. It rarely gets used, but I'm heading in there right now... My son just brought over a digital remastered HiDef version of "Blade Runner" !!! (ie: "Do Androids Dream of Electric Sheep?")

Post: I'm not trying to be a "task master" here, carrying a whip. I also simply do not have the skillset to dive in and help, not without taking some serious time to just get up to speed. I'm just trying to be an advocate for the bulk of the user base...so that it helps the project more than just targeting "newer" systems would... The question that comes to mind is "What percentage of that bulk run optimized applications?" If the percentage is not high then there is little impact by providing an optimized app, further diminished if the performance gains are not great. Sorry if that sounds cruel, I do not have that intent, just being a realist. I tried to build for SSE2, but the errors are great in number and the code looks like it has already been modified once at many of those locations. It might be fairly simple to make it work, but I regret that I have no desire learning the routines/intrinsics. Coupled with the fact that my Intel Evaluation Licenses expire in a little over 2 weeks, there are other things I'd rather pursue. Possibly running VTune to identify hotspots/bottlenecks or substituting more IPP routines to increase readability/maintainability as long as performance does not suffer. |

Post: I would like to thank JD for the encouraging Port of AK's code, now under local test. Further, I would like to thank Crunch3r for his encouragement to JD and offer to help resolve the legal bits should JD want to move towards a public release. Pure speculation is ~8900 if performance scales linear. If my runs with KnaBench are indicative, I'm seeing just under 40% decrease in runtimes overall with some ARs closer to 60% decrease. I'm guestimating RAC should rise by factor ~1.6. for my Q6600 against SSSE3 R2.4V. Am I optomistic? Yes, very!!! I've still got a couple tweaks to try, but will be running them on a yet undisclosed host, my desktop Q6600. It's only got 16 days to make it's move. Running Vista, so it's not as fast as those XP boxes. LOL... Of course, your performance will depend on whether Crunch3r throttles back the code or not ;-) JK Regards, JDWhale [Edit] I could not have gotten this code where it is today without Jason pointing out where my first attempt was hanging. That hint persuaded me to pursue getting VECTORIZED_GAUSSIAN part of the code working and to find the get around to the Mac corr() function with Intel "ipps" calls, Also it was a discussion on Lunatics forum that disclosed a bug an another part of the code.

Post: What must I do in order to make a computer run the operating system and BOINC from the system RAM? Which operating system is best suited for such a configuration? And how much RAM is recommended? I use BoincPE... Boots minimal XP installation from USB memory stick, auto launches BOINC, persists data to network share. You can probably get by with as low as 512MB RAM on dual core, 1GB for quad core if you keep your WU cache relatively small. Personally I run 2GB Dual Channel (memory is cheap these days) because I've setup to have 768MB RAM disk. I'd recommend 512MB ramdisk if you run with 1GB RAM. Caveats: It ain't easy to setup, but the info is on the web if you are persistent. Project detatched WUs are commonplace, esp after power failures and can require maintainance by cancelling the detatched WUs else you get 0.0 credits granted for "Received too late to validate" if both wingmen have already reported (Shouldn't be much of a problem if you keep your cache small, ~1 day). WindowsXP licensing might become an issue. FYI: Be sure to shutdown "A43 file manager" after use... there seems to be a memory leak that can be fatal. BOINC On..On... |

I live in SE Texas (Houston area), 95F summer temps are commonplace, often with relative humidity > 80%. I hate running A/C in the flat, so have gone the opposite of the swamp cooler by running a dehumidifier and an area fan or two to circulate the air. 85F at 40% humidity is comfortable to me with a slight breeze. I do have the A/C to provide a bit of relief when the ambient in the flat gets near 90F. I must admit that I climatize very easily, possibly due to my time in SE Asia without A/C or years spent in NW China without proper heat. Neither the warm or cold bother me much, I enjoy both for different reasons and dress accordingly. I hate paying the electric company and enjoy my monthly 1000KWh ($90) bills. Also coming in from the outside where the temps and humidity are high, it still feels much cooler with the lowered humidity and a slight breeze. Cheers, John |

Post: I have two machines. One has a QX6700 quad core 2.66 chip with 4GB RAM and Windows XP SP2. The other has 2 Xeon 5355 2.66 chips (8 cores) with 4GB RAM and Windows XP SP2. Each machine has the same client version and the same enhanced app on it. I have posted a result from each machine below of similar sized tasks. Why do my cores in the QX6700 run the task so much faster than the cores in the dual Xeon 5355 machine? Any ideas? Your case is normal for 8-core host running SSSE3 2.4V app and might be a memory/cache contention issue. Problem should ease with optimized application transition to V8 based intrinsics code. Keep your eyes and ears on this forum, a solution might be near. |

Next month I should see a rise in the electric bill as I have the swamp cooler powered up and set on the low setting as It's getting into the high 70's to low 80's outside(It's a warm spring here). I tapered off on a P4 single core and a Prescott and powered them off before I left home. That made some room in the monthly KWh to throw another Q6600 together... I've already got the MoBo, DDR2 RAM, graphics card and HSF, so if MicroCenter still has the CPU for $200 and I don't go totally bust here in Vegas, I'll try to get the chip soon after my return home. Only issue will be keeping the chips cool enough as ambient will rise to ~85f in a few months.

Post: So, I had a torrid debugging session lasting a few hours before hopping on the Vegas plane Sunday. Discovered an issue and worked in a quick fix to turn off VECTORIZED_GAUSSIAN, fixed up function GetPeak() to work with different data passed in f_weight array. Maybe too much detail for many, maybe not enough for some.... Will do more debugging work to resolve(hopefully) VECTORIZED_GAUSSIAN algorithm when I get home. All test units pass muster when tested against SSSE3 2.4V app. I had time to squeeze in 2 WUs and posted results before rushing out the door. This is one. Offset is at 360 to help you find the other. Note the bug describing the version of the code. I was trying to get an SSE3 version built for my laptop when I realised that my laptop can only do SSE2. No new WhaleApp for the laptop for now.. But I did leave the E4500 based host, pointed to in WU above, crunching the new app while I'm away. Assuming the 2 already completed WUs validate, I'll upload the ~5 days work upon my return home. Hopefully the electricity doesn't fail and there are a wide range of ARs in the queue. Results for the 2 crunched WUs appear ~20% faster. Regards, JDWhale |

Thanks for offering to save me a sip... quite gentlemanly of you. If serious, drink of choice at home is a fine MACALLAN Single Malt, the older the better and just one sip is enough ;-) Seriously though, We've all got Alex Kan (AK) and others to thank, I just worked persistantly for one day to get the src-v8 tarball to build in the Windows environment. Nothing magic about it. Something is still amiss, and I can't quite put my finger on it. Now I'm having to try to understand portions of the source, and I'm far from being a mathematician. It is much easier to "port" existing code than it is to develop it firsthand, or understand it. Hat's off to the guys & gals that understand this stuff. If anyone is aware of bugs or gotchas in the code pointed to above, please point me to a fix and I'll try to make this happen. I think that I've resolved the convolution/correlation issue in gaussFit.cpp. Someone correct me if I'm wrong, the operator is symmetric so correlation becomes convolution , either operation will work. The only issue is to allocate enough memory for the output and to reposition to exclude taper zones. (if using ippsConv()) thanks again for the support... The original E4500 host chip has moved from the ECS MoBO. Yep the UPS guy delivered the replacement for the failed Gigabyte GA-P35-DS3L. I tried to keep the clock the same @2420MHz with 2x1GB DDR2-800 Patriot. Switch was made at 21 Mar 23:00 UTC. For those keeping close tabs, you might notice a shift in the numbers at that time. Possibly due to the higher memory speed or different chipset. @Pilot - I think I got some of those "HOT" WUs you referred to in another thread and took this MoBo down. Timeframe matches ~Mar 9... Nevermind that the Q6600 was running 3600MHz on air with the memory screaming at 1200MHz. CoreTemp was good 61-56C on PRIME and passed STABLE ...then along comes a HOT wu... and like Pat Travers sings "Out go the Lights". Cheers all, JDWhale |

Just interrested where 2 & 3 simultaneous VHAR processes fall in the mix. Should show up as discreet, clearly distinguishable, gathers for same AR vs. CPU time on plots. I'll crunch them for a short while, then switch back to KWSN_2.4V_SSSE3_MB to run comparisons... For clarification, this host always has 4 cores crunching, I'm only varying the number of VHAR WUs to run simultaneously. On systems with more memory bandwith, this might not be as much an issue.

When playing cards, I like to get the waitress to bring me a snifter of Grand Marnier so I can swirl it and smell it, maybe put a drop on the tongue with the stir stick... Ummm lovely. One's got to keep a level head when at the tables in Las Vegas. But at home, ahhh that's a different story altogether ;-) We digress! Alright, I was preparing the farm to run unattended while I'm away when I came across this host of mine that the project had decided to detatch a couple days ago. (Haven't looked through the logs, don't care too. This did however yield an opportunity. Looking at the results I see that I've been getting 0.0 credits granted due the now famous "Task was reported too late to validate". So I decided to cancel most the "detatched WUs" and turn loose the WhalePort on those few VLAR & VHAR that have a chance to report "early enough" to get validated. There were maybe 10 detatched VLARs, and 6-8 VHAR's that were not "detatched", but that I turned loose anyway, currently running are 4 VHAR WU's simultaneously... In the past, this created the worst case scenario with horrible performance swings from only running only 1 or 2 at a time. 3 others ran with mix of other AR WU's. An example VLAR WU. We'll see how it goes... FYI Host is:

Definitely, not you Brian.... Sorry if I implied so. I will not spend money on development software and persued this attempt with "evaluation" products from Intel & Microsoft. Just give me a JAVA IDE for what I need ;-) Beyond that, I do not have the appropriate hardware to test with, and I really didn't appreciate the "do it yourself then" attitude from some folks, as I wasn't the one who has been teasing people with supposed wonders of great code for months, if not years now (not sure how long it's been)...

Post: Here's an interresting WU <snip> @Fred - The dice don't stand a chance ;-) I thought my quad teammate was/is running stock, that is why I brought up the comparison... I've got some compatable WU's, both VHAR & VLAR, coming up on my quads, but don't want to suspend a bunch of tasks. So I don't know if I'll get them crunched before I leave. But if I finish getting this code sorted... I might be able to turn it loose on one before I leave. Okay, so my 10% OC'd E4500 @ 2418 might not be able to keep up with an OC'd quad, the point that I failed to make is the performance we're seeing from a chip with only 1MB vs. 2MB L2 cache/core on the Q6600. Running virtually clock for clock, the Conroe didn't run away from the Allendale. Rather the preliminary findings are that the "Alex-v8" port to WinXP is ~17% faster per core than v2.4 for this AR on a lesser machine. But then it just might be the new memory sticks I put in that explains the performance we're seeing ;-) -JDWhale @Mark - We'll see, I kind of took this quick port on in response to a couple challenges by folks here on the MB that made it sound hard... So I thought I'd see what I could do in a day. I really don't enjoy coding all that much any more. This was the first code I've messed with in nearly 2 years... other than the BlackJack "basic strategy" tester I wrote in Java a couple months back to test my play (the "Simpsons" yell at me when I make a mistake). Personal record is 500+ hands without making a mistake, but as time drags on the mistakes become much more frequent. Cheers, |

Post: Here's an interresting WU where I was teamed with a Q6600 running optimized 2.4V... So if he isn't OC'd we are running about the same clock as my E4500 at 2418MHz though I've only got 2MB shared L2 vs. quads 2x4 shared L2 cache. I replaced the mismatched memory with a 2x1GB DDR2-800 Mhz set from Fry's ($44) yesterday. So I've been crunching both processors for the past 24 hours or so, CPU times are stable as I've only been crunching the 63.98 credit WUs. To bad the MOBO tops out at DDR2-667MHz... maybe a little more with the 10% OC. I'm moving that CPU to another MOBO so will probably get a new host ID later tonight. Still working to resolve the mid-angle issues though I'm happy with the low and high angles for now. I've run out acceptable WU's to crunch for now so am switching back to 2.4V since I'm heading to Las Vegas for some R&R. I'll Check back in about a week. Ciao, JDWhale |

I was already participating in "distributed.net" in mid-March, 1999, when I first hear about "SETI@Home". In the news/web blurb it was stated that the project would be available for DL on April 5, 1999. On the evening of April 5th, I visited the website and registered... Thus my entry at #16 on the class page for 6 Apr 1999, the date/times on that page are UTC. If I had internet access at work back then, my "join" date would be Apr 5,1999, The first day that the project came public! I'm pretty sure that I DL'd the original "screen saver" to my trusty Pentium 60 at that time, but I know that my registration date is true... Tue Apr 6 02:36:53 1999. I didn't have any insider connections, I'm just a "geezer" in Texas.

Post: Okay... we're back on... I found the error of my ways in gaussFit.cpp. The substituion for the convolution call was incorrect and causing buffer overrun to the output buffer. [Edit] Thanks for the tip, you know who you are![/edit] That's what I get for pulling a replacement function out of thin air, not knowing the exact behavior of the original, and not carefully reading the user guide for the IPP replacement. 12 hours and a pint of Vodka can have that effect. I digress... Unfortunately, I also changed some compile options and don't have any VHARs left for comparison. Prior crunched WU's can not be used for comparison as the host was left unattended and WU's were stalling, thus favoring the WU left running without contention. I've launched a direct comparison of WhaleApp vs. 2.4V...on WU's from same splitter block (I hope that term is correct)... 2.4V wuid=236103546 wuid=236103433 vs. WhaleApp wuid=236103598 wuid=236103652 The WhaleApp WUs haven't reported yet, just kicked them off simultaneously, will perform update as soon as they finish, I predict before 23:00 UDT. Similarly the 2.4V WUs above kicked off simultaneously and virtually at the same time. (never mind the crud at the beginning list, it just shows that I tried to crunch them with the earlier WhaleApp, but they both stalled less than a minute in the run. -------------------------- I know that this is not the best host, but it is representative of what is currently available for folks on a budget.

Post: Hi all, Thanks for all the positive feedback... but all is not well with the WHALEapp just yet. Some WU's enter what seems to be "wait state", mostly within the first minute of execution. Not what you want for benchmarking or daily driver :-( But those VHAR WUs sure haul a**! I'll try changing some compiler options as suggested and try again. I really don't want to debug this, too many years on the job have burned me out. I'll answer the obvious question before someone asks... Yes those constant 913 second run times are true for the 17 credit VHAR WUs. Only thing was I set BOINC to run on only "1" processor on this E4500 Core2 Duo. No memory or cache contention, the whole 2MB L2 mostly for the single process. Just what "High Priority" WUs deserve! I had to shutdown the system to replace that flakey Ballistix memory, the only sticks I had laying around were unmatched 2 x 1GB DDR2-667. This system actually runs better single channel than with the unmatched sticks, but because I've configured the RAM drive (remember BOINC_PE) to use 768MB, that didn't leave a whole lot of memory for the OS & processes, so I went with the unmatched sticks for now. Anyway, I'm putting the little C2Duo back on KWSN_2.4V_SSSE3_MB.exe for the time being. Cheers to all, John |

Post: I have been seeing some short deadline WU on my system that are resulting in both very high CPU temps as well as resulting in many cases in Computation errors. I am running the Chicken Apps. for Core 2 and even when I backed down to stock speed for my Q6600, the high temps still occured with these WU. Temps have soared to as high as 122C in one case before the system did a BSOD. Most often it will spike for a few seconds at 85 to 90C, before erroring out and moving on to the next WU. Might have been one of these that caused my MOBO to fail late Saturday :-( RMA should bring a replacement in a few days. Also a few more BSOD's on another system. Guess I'll suspend any still in the caches 'til conclusive. |

Thanks, Fred W, both for these tests and for all the presentations you make to help us understand some of the stats and bring them into focus. So, if I'm reading this chart and data correctly, it looks like marginal improvement running Crunch3r's old 2.4 ssse3 build rather than the 2.4V ssse3 build. Assuming the app refered to as "new" was the 2.4V app. The newer app seems to make the "sweet" WUs slightly less sweet, but also makes the "sour" WUs slightly less sour. "Sweet" refers to the higher credit/CPU second while "sour" refers to lower credit/CPU sec WUs. I realize that you refered to Angle Range(AR) vs. CPU Time in your presentation, please excuse me for expressing my conclusion based on "current" requested credit running newer BOINC versions crunching those ARs.

"Task was reported too late to validate" ?
(Message 724047)
Posted 10 Mar 2008 by JDWhale
Post:
I've similar issue (project generated detatch events) on a host that runs BoincPE with persistence. I've had a few power outages recently that causes some WU's to crunch and report twice (WUs that have already reported before the power drop are recrunched when power and the network backup, still containing the uncrunched WUs, is restored to the host). Seems that the project doesn't like this and will sometimes detatch (and reattach?) the host without making the WU's redundant. I know that I've never pressed the detatched button, rather the project seems to do it. Maybe we could call these zombies since they seem risen from the dead. A different issue presents when a host is issued WU's and drops power before the next backup...Those WUs become ghosts (I think), the recently sent WU's show up on the project task list for that host, but the host doesn't have the WU's or any record of them, they are not detatched, and wingmen are left hanging til expiration. This wasn't a problem back when we had resends:-( What I can do for these ghosts, if I notice, is drain the cache, then detatch/reattatch. This should cause new results to be generated and sent out before deadline. Is there such thing as being redundant before having quorum? |

Any way you can measure it? In any case, Back to topic, I'm hoping My next electric bill won't go above $176 as It's warming up around here, We actually had a day that was in the mid 70's(Ducks for cover). Wide range of temps here in SE Texas 30-80F like a yo-yo lately. Electricity bill might go up just a bit this month to $100 as I bring the new Q-Ball online and dial her in while letting the P4 Prescott drain her WU cache. |

His overclock isn't as extreme as Who?s SKT near 4GHz with 8 cores, yet this guys RAC is very close with his 4 cores at a lower speed. Us with Wintel boxes can't run Alex code, but we are free to OC to try to level the playing field ;-) Besides, you can buy the DELL XPS 720 H2C factory overclocked and liquid cooled.

Post: Excuse me, but while on the Core2 Quad subject... On this particular processor, Kentsfield, can anyone attest that 2.4 ssse3 flavor is indeed faster and therefore a tastier treat than 2.4 sse3 running on XP 32bit? There might be differences in performance between the Duo's and Quads because of the extra bandwidth required to feed 4 cores on the same size bus. Also, I realize that with the WU Credit Multiplier pending, Crunch3r's build of 2.4V is poised to become the de facto standard, but for right now XP users have a choice between 2.4 or 2.4V. I am partial to 2.4 because of the cache and memory speed printed in the results. While maybe not terribly accurate, I feel it can be used as an indicator of BIOS configuration issues and is therefore somewhat useful. Sorry for that semi-extraneous setup, now I'll get to my second question: Have any of you an opinion on which among the flavors of 2.4 and 2.4V is faster overall on XP 32bit? Please include which of the Core2 chips you are using when responding so that we can reference with Intel tables regarding L2 sizes, frequency, etc. TIA |

For example, when it's time to install a new version of BOINC just bring up VNC connection to a server, stop BOINC service, update BOINC, restart Boinc service, disconnect. So you install VNC server on your "remote" systems. Launch VNC viewer (client) on any system to access any of your remote systems. I'm most familiar with RealVNC, been using it for more than 8 years. (Used to control remote Linux servers running Slackware distribution crunching S@H Classic from my Windows95 host.) Though to be honest, once set up, I almost never had to revisit. It is highly configurable to meet the needs of even the most demanding power user (commercial products are available if needed). You might want to keep display complexity to a minimum on servers and set server properties to remove wallpapers and background patterns and to disable "user interface effects", in order to enhance performance. These tweaks hold extra value with a wireless server/viewer connection. One server property setting that I've found very useful is to allow clipboard updates to/from clients. Cutting and pasting across systems... how great is that? Good luck, John |

I am pleased anyway /salute @Dennis - Thanks for the heads-up on this remarkable HSF. Temps are comparable to what I get with the Thermalrite on a similar rig running @ 3200MHz. While the KINGWIN fan, running fullspeed at 2800RPM, is quite a bit louder that the Scythe 120MM case fan I've attached to Mr Thermalrite, it does move enough air to sail a schooner.  The KINGWIN RVT-9225 is keeping the quad core nice and cool while crunching...  Note the adjustable baffle in the KINGWIN directing air back across the DDR2 1066 sticks. That additional airflow will help when we've settled on the CPU overclock and bump these sticks back up to 2x600MHz 5-5-5-15. No fear here. The North Bridge HS gets plenty hot on the Gigabyte GA-P35-DS3L motherboard, the extra airflow off the KINGWIN helps keep it cool. Now it's time to shop for cheap case to make this brand new cruncher feel at home. Boinc OnOn... |

Post: Yep :( I've capped my computer load at 1KW. With my energy provider (Electric Company) currently charging $.0903/KWH, monthly crunching estimate is $66 with or 66% of my total consumption. Costs can vary from month-to-month with changes in raw fuel costs. I chose not to "lock-in" a fixed rate which was slightly more during off peak months, when A/C use is at a minimum. Here in Texas, electricity can be a cutthroat business with offers coming in the mail weekly to switch energy providers. Some companys are publicly traded, some have recently been taked private by venture capitalists. Competition tends to keep them rather honest IMO. Where I live, I have choice of ~8 different providers. No change in lines or meters, owners/operators of actual equipment remains the same regardless of your choice in provider. Fees for equipment/services (~$6/Month), are included your monthly consolidated bill from your provider.. @Andy - Thanks for starting this thread I've just purchased the "Kill-a-Watt" meter mentioned earlier in the thread, and able to monitor my computer load and see the fluxuations as I'm tweaking boxes. Recent Intel Quad box draws 170W when crunching away, about the same as my 3.2 GHz Prescott box, but is RAC is nearly 600% of Mr Prescott, and generates less heat. Here in Houston, Texas, less heat is a very good thing :-) The P4 Prescott is now destined to become my daughters "new" computer, making room in the energy budget for another Q6600 build. She turns 21 years come June, and is thrilled to be getting Daddys old computer. Cheers, John |

If more contributors were to conduct similar experiments, the combined results would be more conclusive. If one of these hosts cannot obtain work and its queue has run dry, the results are skewed without any evidence that a problem occured. BOINC OnOn...

XP is averaging a 150 to 250+ higher RAC. /salute Just a quick look at some CPU times of WUs with same credit, 63.98 for example, on both boxes, I see no advantage either way. RAC is not a good judge for comparison as it is too easily influenced by factors that are out of direct control. Like pending credits, download mix of WU's. Rather a better comparison is actual CPU times from both hosts for similar WU's. IMO. |

Post: The new voice is too human for my taste. Also, Using a Mustang instead of a Pontiac. I partially agree with your dissent of using the Mustang. But Pontiac doesn't make a mainstream muscle car anymore, and the Chevy Camaro is already associated with Bumble-Bee from the "Transformers" movie. Personally I would like to have seen the brand spanking new for 2008 Dodge Challenger cast as KITT. My guess is that Ford felt threatened by the upcoming competition and paid a premium product placement fee. |

Post:
A very good read, thanks. You will notice that I only quoted a small section of the report. The part that scares the bejesus out of me. Do I read this correctly as your memory subsystem alone draws 85 Watts. Whoa, I've heard that the FB DDR2 DIMMS were power hungry, but this is ridiculus!!! So, I'm guessing that if you were to populate all 8 slots with matching memory, the memory system alone might draw ~120Watts. No processors, no fans, no video card, just the chipset/memory! Please someone tell me that I'm reading this wrong :( My Q6600@3.2GHz and 2GB DDR2-800@1000MHz with RAC ~4000 draws 170W when crunching on 4 cores according to the Kill-A-Watt. (definitely a no frills system) The memory bandwith benchmarks actually look better than I expected, I think that you're near the top of the class in that department, I didn't see latency numbers, but from this FB-DIMM Memory paper I'd assume ~50ns for the 8 ranks on 4 channels that you are running (those are dual rank FB-DIMMs, aren't they). I'm terminating the Intel D5000X dual quad core rampage of recent. In my opinion that is not a high performance/cost effective solution for S@H with the current Windows applications. You might be able to pay for a quad core box like this hostid=3954050 just with the savings on electricity :0 Boinc on... |

Post: Why not spend $650 for a Tesla C870 GPU Computing Processo (128 cores). And not much more expensive if I can them get for $200 ea. I am also thinking that with dual quad core XEONs, 8 WUs can crunch simultaneously. With 4 cores on CPUs, maybe with affinity set with 2 per CPU, I'm thinking that memory contention won't be an issue with those restrictive FB-DIMMS. Am I right here, that the goal is to have the WU loaded entirely on the GPU so that GPU crunching will not require much bus bandwith? Is there still the restriction that each GPU process will require a cpu core? Sorry, if I am asking stupid questions, but it has been a while since I've caught up on this project development thread. Does anyone care to speculate on the potential RAC such a rig might reach, I imagine 4 cpu cores might be ~1000RAC each == 4000RAC. + ???RAC on the quad 8800 GTs. I do not have a clue what might be possible on them. I know that 6-8 years ago I witnessed GPU crunching, Seismic 3D Prestack Velocity Panels for analysis, on the SGI Onyx Reality. Very impressive at the time. I am excited with the performance potential as this project developes. Keep up the good work, "Hats off" (translates to "respect") to all involved. Kind regards, John |

Post:
In that review, it is stated that, [the] "V8 delivers considerable torque to the rear wheels thanks to 16MB of total L2 cache, dual 1333MHz front-side buses, a staggering 21GB/s of memory bandwidth, and eight Core-microarchitecture CPU cores running at 3GHz each". Yet in the shootout when they pitted quad-core Xeons against Opterons, the V8 choked on the Memory bandwith tests, yielding a paltry 4GB/sec for the dual XEON 5355 system. Seems that benchmark was running two threads, running on the same chip, thus utilizing only one of the available FSBusses. Even by doubling the that figure to compensate, bandwith might have reached 8GB/sec, still less 37% efficiency!!! Does anyone know of similar benchmarks on the MAC Pro running OSX with all 8 slots filled with matching FB-DIMMS? Only when I can see those OSX benchmarks will I believe that this performance discrepancy is totally code related. I apologize if this an old subject that has been discussed before. With me being rather new to these boards if someone could point me to any prior discussion I'd be much appreciative. TIA. Can anyone come up with a 4 core MAC Pro to compete against this 4 core Vista box currently in 17th place on the Top Hosts list running Crunch3r's Vista build? Show me one with higher RAC and I might then believe that it is the code. This one doesn't count because he is a cherry picker! @Crunch3r - I've only just began to look at the stock S@H code, Do you know how I can get it to build using MS Visual C++ 2005 Express Edition? (Where is the .prj file?) I would like some time gaining familiarity and experimenting before I even think about porting code. |

Unless the optimized MAC code employs a technique to lower the memory bandwith required, then I do not believe the performance gains are all code related. I have yet to see a 5000x based system running XP or Vista that can beat the memory performance of a tuned dual channel DDR2 system. Though I have no basis for this assumption, I think the MAC Pro running OSX has broken through the 10GB/sec memory bandwith to feed those 8 cores more data than XP or Vista. But then again I am frequently wrong. Can someone running OSX on the MAC Pro please post some memory bandwith and latency test results? |

Post: I’ve got two 5000x systems and can't find any other explanation then Alex's code is better. I’ve poured all over my work units making comparisons to other computers and can't figure it out other then the Mac has a 1.5 times faster app on the V8. I wish it was just a driver issue. When I look at results from your E5320 rig, something just doesn't seem to add up. The processing times seem too high with that 2.6GHz OC... Compare these 2 results of nearly similar AR's one from your E5320 rig, one from my E4500 rig Core2duo with similar OC frequencies. My rig crunched the WU in half the time. I think there is something other than code slowing you down. This difference can not be explained by Alex code, can it? My e4500 is still ramping up, only been online a couple weeks. I expect RAC ~2000 in another 2-3 weeks. If you have 4 times the processing power, then you should be able to attain nearly 4 times the RAC. I just lost a whole day behind a power failure, and all my WU's were "cancelled by server" when it came back online. I wish I could get my hands on a 5000x system and enough memory kits to run some benchmarks and do some tuning. I still think that the problem is with the memory subsystem not having the bandwith. Can you confirm that you are running 8 memory slots, fully populated with matching sticks, in dual channel interleaved mode. Have you done any benchmarking to get synthetic performance numbers? Good luck, |

Post: Just looking at the review & benchmarks of this Crucial Ballistix Tracer memory kit.

Look at the bandwith and latency graphs when overclocked to 1200MHz compared to not OC'd. Check the 3% benefit on Super_PI to 8M digits when the memory is OC'd to 1200MHz And best of all, this 2 X 1GB kit can be had for less than $100 right now! I can't wait to team this kit with a new Q6600 running at 3.2GHz (8*400MHz). I know that when I overclock it to 1200MHz I can expect about 7.5% increase in memory bandwith and 6.5% better latency. Is there any doubt that this memory will boost performance with S@H on my OC'd Q6600? |

Post: Well, since I was cut off from being "off topic" in another thread, here's my response: Ahh a breath of fresh air and a fresh topic. Thank you.
The only application that I am interrested in attaining maximum performance is crunching S@H. I don't run web servers & I don't play 3D first person shooter games. Heck some my machines do not even have hard drives in them, they boot from USB, they were built to crunch. Motherboard, CPU, Memory, USB stick, cheap video card if none onboard, case optional. No hard drives, DVD drives or expensive video cards that run up the system price and electricity bill. My running benchmarks is a key step in the iterative process of maximizing the system performance by tweaking the system at it's lowest levels of assembling hardware and BIOS performance settings. I would include running a S@H benchmark if a comprehensive one could be made available, but I fear that with the wide assortment of hardware and assortment of Work Units(WU) being split and combination of WUs being executed at any given time on dual- or quad- or octa-core systems, such a suite of S@H benchmarks might be too comprehensive to ever finish. I do my own S@H benchmarking by using preemptive WU schedueling and comparing CPU times for comparable WUs executed with WUs of all types, but that is a different topic. I call that "schedueling WU's" rather than benchmarking. So what I do to tweak performance of WU crunching is to run and analyse synthetic benchmarks that measure memory bandwith and latency. This part is pretty straight forward, maximize bandwith, minimize latency, do not let one suffer too much because of the other. Try to minimize Super_PI run times, not only on a single core, but on all available cores. Lower is always better on single core, but a significant performance as the number of cores running Super_PI increase tells me that I am memory bandwith restricted, the same can be evidenced by running 4 cores of VHAR WUs simultaneously my thoughts on that have been posted on other threads. The problem with running S@H as a benchmark is that it takes too long to complete the tasks when I am doing the hardware tweaking. Maybe an hour or two to crunch the WU's, getting the right mix of ARs downloaded, and synchronization is a real b!^&#. But what I can do rather quickly is to fire up Everest to check memory bandwith and latency, run Super_PI to check some number crunching combined with memory bandwith, and run Prime95 to check stability and core temperatures. This testing can be performed quickly. Prime95 is not really a necessary stress test since my overclocking is not extreme but I do run it after Super_PI has reached it's limits. So I then record the results and go onto another tweak iteration within 5 or 10 minutes. I move that the "controlled test" isn't done properly. This is why many companies (including AnandTech.com) have started developing their own test suites to get a more accurate picture of the expected role. AnandTech has done a great job in developing their own server tests which paint a much more realistic picture as to what the hardware can do. Doesn't apply... this is a SETI Number Crunching forum, not a generalized server performance forum. Folks that run S@H on servers built for other purposes and actually do just let SETI run on otherwise idle CPU cycles probably do not make maximizing S@H performance a priority.
Not unicorns, but true racing machines just like Thoroughbreds are among horses, bred to finish first.
True, run the benchmarks across a wide range of hardware and pick the sweetspots that overlap. I don't think that you will need to get so specific as to the chipset on motherboards, processor family is probably good enough. In the case of S@H, weight the results toward the hardware distribution contributing to the project, and maybe toward the newer technologies a bit. Most of the major project performance boosts will be with the newer hardware as it proliferates due to lowered costs and reduced power consumption that make them cheaper to own and operate.
Feedback is good, but please do not dismiss the benefit of using benchmarks as a tool to measure performance. Yes focusing totally on a single benchmark is wrong, but when a single benchmarks results clearly show a problem, then one has to wonder why and see if adjustments can be made to resolve the issue. IMO. Like OZZY says "I'm going through changes" and so is computing technology. Rock on OzzFan, John |

Posted 25 Feb 2008 by JDWhale
Post: What I'm hoping to get out of this thread is probably a little different, because I'm looking at the programming side. Some idea of the dynamics at work as far as threads & memory bandwidth requirement is nice. What I gather I'm seeing so far is 8 cores all operating on different data, cramming the Memory &/or FSB until they choke. [I would argue this phenomenon would still occur on desktop DDR2 etc ...and MACs too ] Yes, yes I've noticed on my E4500, running Single Channel because I didn't have a matched set of sticks at the time, that setting in BOINC user preference to only use 1 processor, that I could run 2 WUs faster by wall clock time than running those same 2 WUs simultaneously. That factoid hastened my purchase of a matched set of sticks and tuning bus frequency for data throughput. Though I've just started looking at the seti_client code (fetched from berkeley last night) what I'm seeing in the first file I've looked at to interesting and some experiments that I want to try. Can ths project by built using MS Visual C++ 2005 Express Edition like BOINC can? Also maybe I should look to Lunatics site and start with the optimized code, It may turn out that 8 cores working cooperatively on a single task [or perhaps one per socket] in finer grained parallel fashion may be a more efficient use of the bus ( Reduce Bus throughput requirement by 8(or 4), cleaning up the cache demands at all levels and hopefully bringing the software back to being CPU bound (which we can overclock ... :P) More yes, yes, yes!!! With the release of multicore systems, I pretty sure that efficiency can be obtained by using finer granularity than just launching more processes. Use more threads in the same process! Have you looked at the data transfer rates between cores? On my Q6600 running at 3.3GHz I'm getting over 300GB/sec intercore transfer rates on 32kB-64kB block sizes!!! This reminds me of programming the SGI Power Challenges & Origin servers. Huge amounts of shared memory(16-128GB) with 16-64 CPUs all working on 1 common task rather than matching the number of tasks to the number of CPUs. Just a thought...Maybe check if the WU's processing could be set up streaming across threads, or just break up the WU in to chunks assigned to respective threads. Of course one of the prime benefits to all this is that performance would not suffer if running on single core system. And I guess that you could still honor the BOINC request of max number of processers and just use that many threads. If your quad core is running hot, just cut the number of threads to 3 ;-) Please slap me if I'm sounding stupid. This discussion might be better off in a new thread and bring in some new programming blood. Edit: [ot] Just got back from MicroCenter with a new Q6600 chip for $199!! WooHoo!! [/ot] |

Post: Then I proffer: what good is maximum potential if it can never be achieved? Because they give you a performance target. Ok OzzFan, Just because the benchmark is "Synthetic", does not mean that they post the theoretical limits, rather I've never seen a benchmark that came close to posting theoretical maximums. Those Synthetic Benchmarks truely are achieving said performance under a controlled test! Obviously you feel that this type of testing is worthless, but it does give some of us programmers a target to aim for. And to me, that information is not worthless. I want my programs to be able to achieve that performance when necessary. Okay we disagree on the usefullness of the numbers and I see the charts & graphs as something more than "pretty pictures" just to look at, rather a valuable tool to use when assigning block sizes for memory access in this case. It's okay to disagree, even if, in your opinion I'm wrong. I will not discuss the validity of benchmarks any more in this thread, their validity is off topic, IMO. Start another thread, please. |

Post: I just don't trust synthetic benchmarks anymore. They really don't indicate real world performance (but I'll admit they're fun to look at!). Maybe not, but they can tell you performance under ideal circumstances. Of course, actual (real world) performance will be different for everybody. The "synthetic benchmarks" really are moving data at the rates indicated, and do provide basis for comparison. Isn't that what benchmarks are supposed to do? Take, for instance, the EPA Mileage Estimates used to rate the fuel efficiency of automobiles here in the USA. Very few people, if any, truely do achieve those City/Highway numbers, though I do get pretty darn close. Driving habits and conditions vary for each driver, but the numbers do still provide a basis for comparison, their purpose. |

Post: I did an 'enforced test' of this when I got my octocore (Dell Precision 490 workstation, OEM version of Intel 5000 board, supplied with 2 x 1GB FB DIMMs @ 667). It felt really slow as a SETI cruncher - speeded up by about 25% when I put in an extra two DIMMs, as you can see here. Thanks for refreshing our memories with that thread, now imagine feeding 8 cores like Skulltrail is doing, and I think you see performance stepping back to similar to before your memory upgrade!

Post: Directron has some specialty gear at great prices, picked up Thermalright 120 Ultra Extreme there the other day. I've been buying from them for years, plus it helps that they are in the neighborhood. Generally though, prices are better at NewEgg and I've found NewEggs online chat with customer service representative very handy for instantly resolving any billing issues that may arise. Delivery is always fast with their 3-business days UPS service and shipping is often free:-) Be sure to subscribe to their newsletter for promo pricing on a wide variety of items weekly. I've also picked up some items at Frys.com. Sometimes I think that they misprice items by applying rebate deductions directly to their merchandise and then still offer & grant the rebate. Got a couple of video cards from them in the past 3 weeks, free after mail-in rebate. Granted, it's not the latest hi-performance video cards, but the GeForce 6200 more than meets my needs. it has a heatsink and not a fan, and is a power miser, so is both quiet and is cheap to operate. They also had the Antec P180 case for $70 after $30 MIR, though that was too expensive to ship, so I picked that up at the local Frys store, same price. That giant Thermalright HS from Directron fits perfect on a NewEgg Q6600 in the Antec case from Frys. Maybe I got carried away with details, but the point is that it pays to shop around and high performance computing need not be too expensive. Sometimes the best prices can be found in your own backyard. Good luck, John P.S. I'm still keeping my eye on you in my rearview mirror, Bob in Fl |

I would tend to believe those numbers OzzFan, I just had a peek at some of your results. Granted you are running stock application, but the variations in runtimes for your VHAR WUs is maybe 30%, I think the differences can be attributed to the varying WU mix and with it, the varying bandwith requirements to feed the cores. It's been my experience that you need in excess of 8GB/sec to get similar runtimes on VHARs feeding 4 cores. You might try setting your local preferences to use at most 3 processors antdsee if your CPU times stabilize. If they do, then it confirms a bandwith issue. Sandra just might be your friend. |

Post: my DDR2-800 running dual channel @ 960 gets ~ 7.5GBytes/sec too [On SiSoft Sandra Lite]. Checking the List of device bandwidths wiki, the theoretical is somewhere between: Right, I was using the Oz-imposed theoretical max of 8 times bus frequency* multiplier, not taking into account dual channel. So according to the "Synthetic Benchmark" results and Wiki theoreticals, we're at ~ 47% theoretical that's a bit more believable. That puts us in the ballpark of what OzzFan was saying of actual being ~theoretical/2.0 Thanks, John |

Did you take into account that it is "1600MHz dual independent Front Side Busses" ? Lets look at Dells just released Precision T7400 specs, another Intel D5xxx MOBO solution running the X5482 Xeon like some of the leading MAC PROs. Memory Bandwidth Up to 32.0 GB/s of theoretical memory bandwidth for 667MHz memory in quad channel mode i.e. 4 DIMMs Up to 38.4 GB/s of theoretical memory bandwidth for 800MHz memory in quad channel mode i.e. 4 DIMMs They also claim data transfer rates of 12.8GB/s or about 33% of theoretical max. Come on Ozz, my DDR2-800MHz gets 6-7 GB/s running Dual Channel mode, this D5400XS should at least get better than that in "dual channel interleaved" mode. Shouldn't it?

The 1600 MHz Front Side Bus (FSB) is a quadpumped bus running from a 400 MHz system clock making 12.80 GBytes per second data transfer rates possible. The 12800 GB/s is 12.8 GBytes. In specs "B" is for bytes, "b" is for bits, IIRC, it's been many years since I used my 56Kbps modem (Kbps==Kilobits/sec);-) -John |

That was a nice story about helping your sister, Jason, we should all be so lucky to tweak MAC Pro hardware to fit the application, hands on, rather than trying troubleshoot from the sidelines. Sounds like fun! Those Wolfdales are great chips, I love both high performance and saving energy, if only the auto makers could deliver on that front. Now to the meat... Warning: The following are my expressed opinions and are not those of my former employer or any other persons, living or dead. I take full responsibility for expressing my own ignorance and am not being forced to make these statements. It's my understanding, both from lurking in this forum for many moons, and from my hands on experience with these Multi Beam WU's, that there are different resource needs depending on the WU's being crunched and the hardware a user employs. I fear that high bandwidth on multiple cores most directly affects CPU times when crunching multiple Very High Angle Range(VHAR) WU's. Crunching 2 of these WUs simultaneously can hinder the performance of a Core2 Duo by as much as 50% or more, if your memory subsystem isn't configured optimally. Crunching these VHAR WU's demand an almost constant "Read from memory". They just can't get the data fast enough, if you throw a faster processor, you better tweak the memory some more, too. These VHAR WUs also have the greatest credit reward potential. I won't get into any more details about that in fear of cherry picking WUs, (Yes I've tried it, purely for testing purposes;-), and feel that highly efficient scheduling of WUs has more potential RAC benefit than cherry picking). Crunching other types of WUs have other requirements and the memory subsystem is not stressed as much, faster CPU's are just what the Dr. ordered for these. But consider having to run these "other", non-VHAR WUs in an environment where the bus is already saturated trying to the VHARs that are running. Now you've slowed down the non-VHAR WUs because of the memory bottleneck. (I've been solving these types of behavior in my workplace for years, remove bottlenecks/increase performance, repeat.) I don't profess to be an expert, these are just my opinions gathered from my observations and experimentation. [ot] Please excuse my [apparent] obsession with trying to milk the most of every CPU cycle, but after all, it's hardware that I paid for and I'm the one paying the electricity bill. The obsession might also come from years of trying to get just 1-2% performance increases, at a time, in high performance computing environments. Knocking just those 1-2% might mean the difference between bonus and penalty on very large scale pre-stack depth migration jobs that would require an much as 6 months to complete running 64 CPUs in shared memory. I worked as a programmer in seismic data processing and 3D visualization/interpretation. Yes, I might be dating myself, I'm sure that with todays compute clusters the runtimes are down to just a month or two(probably mostly waiting on the analyst). Witnessing SGI demonstrate the migration computations on the graphics hardware was very impressive, but it was just a demo at the time. I can't wait till I can try crunching SETI on a GPU. Of course, then I'll have to buy a real video card :-( [/ot] I'm just trying to get a grip on what this D5400XS/QX9775 system called Skulltrail, just now coming to market, might be capable of with the optimum configuration. There seem to be so many ways to configure the memory and the reviews aren't helping because each one seems to be using a different memory configuration, the bandwith just doesn't seem to be there. I'm convinced Intel has crippled this board by not putting enough memory slots to feed the 8 cores from the required FB_DIMMs, and fully utilize the chipsets dual branch, dual channel; dual channel interleaved; quad channel, call it whatever you want, memory subsystem! Looking back at the page that Alinator referenced, Frontside Bus Properties
Bandwith 12800 MB/s
Memory Bus Properties
Bandwith 20640 MB/swhere is all the bandwith going? This system only reads at 3.8GB/sec with the configuration that this reviewer chose. Do the FB-DIMMs only allows this board to read from memory at 30% efficiency? Is that the performance penalty for using FB-DIMMs? Isn't there anything that can be done with the configuration options to tweak this thing to respectability?Like I've stated before, my core2 Duo E4500 at 2528Mhz on an ASUS P5B-MX runs the VHAR WUs faster than the Skulltrail, granted I process only 2 at a time, but I fear that I'm nearly saturating the bus (Read=6GB/sec, Latency=74.1ns according to Everest Home Edition) with just 2 cores if running 2 VHAR WUs concurrently. Just imagine the performance penalty trying to feed 8 higher power cores that are running 58% faster with less bandwith. I build my own systems, so this box (Skulltrail) is not for me. I'm just trying to get my head around all the numbers. Remember that it was my career 5 days a week to get the most that the hardware had to offer and to increase efficency to collect the bonus rather than paying a penalty. Sorry I rattled on for so long, It's time to go knock about some golf balls. G'Day, John |

Post: Hmmmm... Thanks for straightening me out Alinator. Now I'm totally confused, I've seen that page from Toms before before... Clear as day "Quad Channel". Can only using 1 FBDIMM per channel explain the 3.8GB/sec on the read benchmark on this page ? Granted 7.1GB/sec for writes is stellar, but come on 3.8GB/sec reads will not even feed a Core2 Duo properly crunching SETI (my e4500 chip on ASUS P5B-MX reads at 5.7GB/sec (according to Everest) and still can't do 2 VHAR's without penalty! Something is still amiss on this board. Maybe it would perform better with Dual Channel, 2 slots each. LOL The reviews just do not add up, only constant theme is that this board is bandwith constrained. [edit] Maybe the Anandtech wasn't too screwed up after all, under photo of the memory on the page you linked it states Dual-channel memory mode is supported as well.and in the photo of the bios shows "Branch mode" options (Single channel).

Post: Not so sure that you guys have read the stories correctly. It appears that the Skulltrail does have 4 channel memory just like the MacPro. As I read the story the complaint is the need for 4 sticks to take advantage of that. Most of the overclock tests were only done with 2 sticks, thus the memory bottleneck. I disagree, you better read the review again. The testbed states they have 4x1GB sticks of 800Mhz FB-DIMM occupying the 4 slots, the BIOS display shows each of 2 channels with 2GB each. The other channels displayed in the BIOS as "Not Installed" because they are not on the motherboard. All 4 slots are occupied in the MOBO photos. Memory performance would have been increased (nearly doubled) if they would have had one slot per channel rather than 2 slots per channel(i think), or 8 memory slots like the similar DELL or MAC PRO systems. [edit] Other boards based on this chipset might have 4 channels, but I fear that the D5400XS, the board teamed with dual QX9775 CPU's to make Skulltrail, does not! [/edit] |

I guess it would have added to the confusion if the D5400XS used different memory (DDR3 -vs- FB-DIMM) than the other D5000 boards. So instead, our friends at Intel crippled the board by only using Dual Channel FB-DIMMS. And in all the hyperbole (hyper bull) you know Who? was spreading, this little factoid was conveniently quashed. 'nuff said... |

I think it's pretty poor of Intel not to give access to Quad Channel memory on there "BEST" system, yet us mac users get it on standard chipped systems. If they just would have went with DDR3-1600 the bandwith would be closer to 12GB/sec Dual Channel rather than the paltry 7GB/sec that it's getting now. When you are spending that kind of cash for MOBO and CPUS, what is another $300 for 2GB of DDR3 RAM?

Post: The picture is coming together for me now... After reading a very good review of SkullTrail at anandtech.com, the dual QX9775 crunching mystery has been solved. The main bottleneck is the D5400XS motherboard only having Dual Channel FB-DIMM memory system -vs- MAC PRO uses Quad Channel. Half the bandwith of the MAC PRO. The box is doomed to perform less than DDR2 Dual Channel systems because of increased latency of the FB-DIMMs. Bad news when high bandwith is required. Final words on page 16 sums it up: "Skulltrail is closer to perfection than Intel's V8 platform ever was, but it's still not quite there. Let us use desktop memory and Intel will have a winner on its hands." I can now sleep at nights. |

I fear that the MAC is being memory choked, just like the Skulltrail(SKT). I don't think that WindowsXP has the proper drivers to use the quad channel memory system to its potential.

Post: Started a new experiment yesterday: I've installed Win XP Pro x64 on my 3.0 OctaCore and Seti is running now with high priority... Performance looks dismal... about 2 times CPU time for the shorties... 800 sec on OS X vs 1500+ secon WinXP... I roughly guestimate you will top out ~6500 RAC on that XP box... Possible still enough RAC to make you the top Windows box with 8 cores maybe in the same ballpark as SkullTrail. Is this due to IO bottleneck? I don't think so, the other WU's also underperform OS X. Why won't Windows perform on the same hardware? It might be something in the Windows Core I/O that doesn't allow the performance. I'd be interested in the results of "Everest Benchmarks - Read" or SiSoft Sandra "Memory Bandwith" with similar benchmarks on MAC OSX, if available. Why can't the same hardware perform similar CPU times on the two different OS platforms? Does the difference lie in the OS? Does Windows limit performance somehow? If so, and WinXP can not even come close to competing on identical hardware, then it only demonstrates that Windows hinders performance. Maybe Windows is lacking the proper drivers to allow the hardware to perform near potential. I've heard rumors that newer drivers must be "slipstreamed" to the XP distribution to raise performance. But I've not followed up since I do not have the hardware. That must be a chore. Maybe the differnece lies with the more efficient MAC "Alex Kan" code. Call me ignorant but with 20+ years as a coding professional, I need to see similar benchmarks before I can dismiss this discrepancy to application code! I don't know... but someone at Intel and Microsoft does, and it's probably a closely guarded secret. UL1, thank you for trying my proposed experiment... I would understand if you abandon this as a failed attempt whenever you see fit. Dang it... I'm curious enough that I want to find room in my budget to purchase the hardware just to try to explain the differences. But honestly, I can not justify the expense. Cheers, John |

So what you are saying is that the current SKT memory subsystem is not yet able to fully utilize performance potential of FB-DIMM. Does this explain the 7GB/sec ceiling on memory reads? Maybe we can expect this figure to nearly double, that the true and all powerful SKT is only a few (2-10) months away? |

Yes, the processors are fast and you can overclock all you want, but the problem is that you have not demonstrated that you can feed the beast and the processors are being starved. My DDR2 PC6400 gets 8 GB/sec and even that is not enough to fully feed my single little old Q6600. How can it be enough bandwith to feed 8 cores that are running faster?

Post:
Seems like we're thinking alike, that's the same heatsink I used. In case you haven't seen it Anandtech review was quite good. I used the same Scythe fan they used in the review, nice and quiet and plenty of airflow. Be sure your case have 7" clearance from top of motherboard (fits perfect in my Antec P180). I'm not crazy about the wire brackets to hold the fan in place. Though they do seem to work, I'd feel more secure with screws or a plastic clip. The HS that I bought had the modified mounting bracket, so that resolves the issue in the review about need to "bend the Socket 775 adapter". And you probably already know that you'll have to pull the motherboard to mount the backplate. Good luck |

Post: It does support 1066, but the price its a little out of reach at the moment. The PC gets used for other things, including Video editing, so thats why I was thinking of the 4GB. With 2GB it is ok for editing, but the extra 2GB might help a little with speeds when video editing etc. Sorry, I'm not familiar with video editing and it's requirements. I guess the first thing I'd checkout would be if your system was running low on memory and starting to hit the swap file when you are running your program. If not, then adding more memory probably will not help much, but replacing your memory with faster memory can sometimes make a huge difference. Hardware prices vary so much regionally also. On my current DS3L board, I'm running Kingston ValueRam KVR800D2N5K2/2G (2x1GB sticks). The motherboard allows OCing the memory to 1000Mhz at 5-5-5-15 timings. And the memory is cheap! CPU runs at 8x400Mhz for a 3200Mhz OC with a good aftermarket HSF. I'm assuming that when doing your editing that you're shutting down BOINC to free up it's memory, granted that it's only about 200MB, but every little bit helps. Good luck, |

Post: I am heading down to Sydney early next week and while I am there I was considering upgrading the RAM on one of the Quad Cores. I am running a Q6600 on a Gigabyte P35-DS3 motherboard If you're doing the upgrade to help S@H crunching, and it's not needed for other reasons, then 2GB total is plenty. Also, that board supports 1066Mhz (PC8500), doesn't it? I'm trying the Crucial Ballistix 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory in my next build with the P35-DS3L next week. Reports say it'll do 3-3-3-8 1T @ 800Mhz, but I can't confirm yet. Good luck |

Come to think of it, I'd better get 2 systems so I can run the test simultaneously ;-) It's not going to happen!!! At least not in my BOINCing room. My guess is the MAC OSX box will get to about ~13000 RAC given enough time, and the MAC WindowsXP box would definitely be the fastest Windows cruncher on S@H and be in the same ballpark.

Running the optimized MAC application on that configuration (OSX on Windows). If the assessments that the MAC application is so much faster than the optimized Windows app, would the increased performance be enough to offset the VMWare overhead?

Post: I had a MacPro running Windows XP Pro via Bootcamp and crunching QMC. When I stopped this experiment after two weeks it had reached an RAC of about 7.000 and was still rising... Just looking at the QMC Top Hosts, RAC of 7,000 would put you firmly in 2nd place behind 16 cores of Intel X7350. Am I reading the numbers right? I am assuming you were running 8 cores of either X5482 or X5365. Either way, I would think that RAC of 875/core is quite impressive. Of course that just might be my ignorance showing as I know absolutely nothing about QMC. |

Post: Just a thought, I don't know if it's even possible and I realize that there would be some overhead. What kind of performance could I expect from the optimized application running in WindowsXP via VMWare? Wouldn't it be a hoot if the MAC could run Windows version of Seti@Home faster that a similar configured native Windows box. Of course I'd want to run the test the other way as well and install Darwin on my native Windows box to see how the optimized MAC application performed there. I first used VMWare, at home, about 10 years ago and as recently as 5 years ago at work, the performance was painful to run Windows 2000 on my Dell Precision workstation running RedHat native. Is the VMWare performance any better these days? If I had the cash to throw down on a MAC, I'd be running the test myself, if possible! -John |

I recall noticing a "runaway" workunit, one that had exceeded it's estimated runtime and was still less than 50% complete back on Feb 13 or 14 and had cancelled it. Coincidence? Maybe.

(Message 714636)
Posted 18 Feb 2008 by JDWhale
Post: However much RAM you install, try to go with dual channel wherever possible. I agree with OzzFan.. Go with dual channel when possible for maximum speed transfering data between CPU and RAM. Take particular care in the the requirements of dual channel with "matched" memory sticks, memory performance can actually decrease otherwise. Looking at results 749134830 and 749056752 from your Q6700, I can see where your system might be somewhat memory bandwith limited. Both results requested the same credit and have similar flops, yet CPU time varies by ~35%. The slower of these WU's was probably choking trying to read from memory. This was just a quick look at your results, I wouldn't be surprised if some variations were ~50%. This type of behavior can/will occur when 2 or more WU's of "Very High true_angle_range"(VHAR) are run concurrently. Your crunching performance will improve on this type of WU's by tweaking your memory performance. Good luck, John |

I have a bit of an issue with the "unused cycles" argument when it pertains to newer "speedstep" processors. If I wasn't running S@H, then my CPU would throttle back to 6x multiplier and power comsumption would decrease considerably, rather S@H keeps the CPU with the pedal to the metal and causes the processor to create more cycles so it can run. I'm a dedicated cruncher, so throttling back isn't something that I'd want to do, but S@H uses more than "unused cycles" these days. Hmmm..

Post: Maybe slightly off topic, but I'll give it a try anyway... The last time I checked, credit is useless. That is, until the credit can be used for something. Granted, bragging rights have some value if you need an ego boost, but that is about it! I started running the Seti@Home project for the science back on the first day that the download was made public and have crunched 24/7 since on a variety of hardware. I've retired the old Pentium 60, PII's, PIII's, and SGI Power Challenges, and am in the process of retiring the P4's in favor of energy efficient Core2's. Rather than focusing on credits granted and older BOINC versions, wouldn't it be more appropriate to limit hosts to those that are more energy efficient. Try to raise the bar on the science performed per KWh. BOINC is going GREEN, I fear NOT!!! When you consider the energy consumed by those inefficient hosts whose sole reason for still being powered up is for BOINCing, it's quite wasteful. Please don't get me wrong, Pentium 60's and PII's can and still do valuable science for the project. Just at too a high of a price. Let the BOINC projects take some responsibility for the BOINC footprint on the global environment. Regards, John |

Post: There's a pair of settings which can be put into the project configuration to warn users that a change in minimum allowed core client is coming. One setting says what the minimum will be, and any hosts which are running a lower version will get a message in each Scheduler reply saying: Mark... It my understanding that there will not be any "strange message popping up" on anybodys computer, rather a subtle message in the log, viewable under the "Messages" tab of the Boinc Manager, and probably unnoticed by the most of those receiving said message. (Joe please correct me if I am wrong). Joe... What happens when the elapsed time passes and the "minimum version" is enforced? Are WU's blocked from being sent to clients not meeting the minimum BOINC version criteria? Thus not "wasting" cycles on a host working on a result that would ignored upon completion anyway. It is my opinion that this is the most elegant and non-intrusive solution. My main concern is that of impact to the projects data throughput. Can we quantify the amount of work that would be lost by those exiled (for lack of a better term) hosts? Regards, John |

From your earlier post... In other words, you get what you ask for, unless it is higher than what is currently correct, and if you claim a lower amount than what is currently correct, that is what you get, and the wingman is not punished. So if I'm reading your earlier post in this thread correctly, If you ask for 0.0, then you get 0.0, even though the "currently correct" credit might be 50.14 and your result is used to validate your wingman who gets the 50.14 because that is what he claimed. What happens in the case that user one claims 25, wingman claims 102, and the currently correct credit is 63.98. Both original users validate without issue, but both have in correct credit claims?

I've a feeling than in addition to those who set-it/forget-it, there are those mom & pop types that are only running SETI because junior installed it while at home on spring break, or something similar. Years pass and never an update to BOINC, though SETI updates the crunching application automatically as new versions become available. What if SETI were to install a "do nothing" application, like a detatch from project, to those volunteers systems that haven't a minimal version of BOINC installed. Something along these lines would attack the problem at the source, WU's never get DL'd to those out of date systems so there isn't an issue with credit handling after processing. Seems to me that since the mechanism is already in place to update the application as needed, the framework would already be in place to implement this approach. Of course, we'll be losing production capacity in a time that the project is in need of more crunching power, not less. I wonder what the impact to the project would be.

Post: Possibly suffering from memory bandwith shortage... as these VHAR WUs tend to preempt other WUs, it's not uncommon for 4 to run at a time and saturate the FSB. I don't see any evidence of other AR WUs in your history suffering such a performance issue, there are even a couple of instances of VHAR WUs that seemed to have crunched in a mix with other ARs and performed admirably. You might try running Hyper_PI and compare performance of single core vs 4 cores, 20% increase in runtimes are acceptable, 100% increase is not! I had similar issues with an economy ECS motherboard and an E4500 chip, the dual channel performance was very poor with only about 10% boost over single channel performance. Good luck, |
