I'm a Microsoft TechNet subscriber ($350 US for new users, $250 renewal) and get 10 licenses for all current OSes as well as most of their library of software, and each license can be activated up to 5? or 10 times without having to call MS. I always forget about the TechNet subscription. *bonks head* It's 10 activations for MSDN, maybe 5 for TechNet? Either way it's a good deal to get access to many OS's for testing. I was told the date by our MS Partner guy. He's said the RTM date was the 13th. This is also the date of Worldwide Partner Conference he will be attending. Might not be able to download the ISO till the 14th maybe. As that is also patch Tuesday. I just hope it shows up ASAP as we need to have all if our testing done by August for all of our products..... in 4 languages.

Well that gives me something to look forward to on Monday or Tuesday of next week. I just haven't decided if I'm going to stick with Vista on my main machine or do the upgrade. I still have a couple minor reservations about 7, but I may just decide to go with it anyway. |

I still have a couple minor reservations about 7, but I may just decide to go with it anyway. On the one hand. The new neat things, fixes, & improvements. Then on the other. It's Windows 7. Generally with Vista & Windows 7 I just turn stuff off, and rip things out until it's basically XP.

An idea for you to try Install a version of Linux that does not automatically require you to run the GUI, Such as Fedora, in black screen mode (you can start the GUI any time you want by doing... startx). Reasoning; You need to remove every possible "other" process from the system that you can so that the seti app is one of just a few running. If the system is spending less time starting-stopping-queuing-rescheduling processes then it spends more time crunching. You can turn off/ disable all the unneeded server type functions and other stuff that you wont use.. even sound cards etc if you like. Think of it as being sort of like the RISK systems built a few years ago... stripped to basics Assuming you are behind a firewall/router running on another machine You can also adjust the seti apps "active running-time" by fiddling the priority level a bit.. "carefully" eg setivalue=`ps -au | grep seti | cut -b1,2,3,4,5 | tr -d " "` renice -3 $setivalue This will adjust the currently running seti app process number that is currently assigned to the app so that it runs just a little slower than the systems actual kernel components. If you want to do a time based test over a few days you will need to embed this into a script and fire it off every half hours or so to catch the new jobs starting after the old one finishes, remember every new job has a new PID Process IDentification number. |

Ignoring all benchmarks, from any source, that you may have seen for those two dells. The RAC and total credits are about what I would expect for Seti. Both the MB and the AP apps like L2 cache memory. The Intel has a fair bit, the AMD hasn't got a lot. Somewhere in Pappa's pile of computers he has or had an AMD X2 6000 its BOINC benchmark figures are similar to my E6600 and my Q6600. When we were testing the AP app on Beta before release here it was noted, during the period when they were trying to find out what the credit rate should be. That my Intels were over twice a fast as his AMD, and on the old claimed credit calculation which is based around time * benchmark and Pappa's computer was claiming lots more credits than my Intels. |

Without any claim of scientific correctness here are my latest MB results compared to my wingmen: Mine CPU is an AMD Opteron 1210 running Linux at 1.8 GHz, with optimized app: Mine 8,436.64 s Intel Core Duo P7350 2.0 GHz 10,426.99 s OS Darwin 9.7.0 Mine 3,446.44 s AMD Athlon 64X Dual core 5000+ 4,429.34 s OS Windows Vista Mine 8,670.04 s Intel Core2 Duo T9400 2.536 GHz 7,650.38 s OS Windows XP Mine 9,952.87 s Intel Pentium 4 3.00 GHz 22,421.97 s OS Windows Server 2003 My L2 cache is 1 MB/core that is 2 MB although BOINC sees only 1 MB. BOINC client is 6,6.31, which declares to be 6.6.29. Tullio |

So over the years turning off Services that were either Security Risks or were not needed to slim down the loading of DLL's on startup, can produce a fairly lean machine. Anyone have a URL with a current recommended list to accomplish this? I used to disable a few based on Blackviper's list (iirc). Have a new XP Pro rig that still needs done, so the quoted idea is very timely for me. |

Oh I'd forgotten all about seti loving L2 cache. I was just noticing in some playing around on some systems here. PII Xeon 400/1mb is quoting me 12-14 hrs. Where a PIII 850/512kb system is quoting me around 25hrs for completion. Checking those two dell systems with cpuz the amd is displying 2x512kb where the intel shows 2048kb. I think it's a shared cache on that version of the intel chip. SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

i have tried other operating systems such as various flavours of linux. keep in mind i am no linux newbie. i have been using linux for years. but seti does not seem to play well with linux. once you install the boinc client on linux, you start it up and try to choose which boinc project to attach to. something is wrong with the screen which displays the list of projects, its difficult to click on any of them. very difficult. once you get past this and get boinc up and running, scrolling doesnt work. you cant change the columns in any of the tabs of the advanced mode client. want to optimize seti under linux? its a real pain since boinc has to create a special blinc account under linux from which to run boinc. you have to log in as root to even access the boinc project folder. once you setup the appinto.xml, add the necessary optimized files and restart boinc, i find that it frequently crashes. alot of times the minimize/maximize wont work, and boinc gets stuck being a miniature box that has nothing to click on. rebooting doesnt seem to help. it just seems to me that the linux version of boinc is quite a few generations behind the windows client in terms of usability and stability. there is even a version of linux out there that comes pre loaded with boinc and fits on a thumb drive. while it is nice having boinc work out of the box, all of the issues with scrolling, lack of column support, etc are still there. as well as the painfull process of optamizing seti. with windows, you install the boinc client,attach to seti, suspend set, run the lunatic optamize program, resume boinc and you are done. its painfully easy and you dont even have to know the install directory because everything is done for you behind the scenes. so yeah, i run windows xp on my crunchers with as many service and xp features disabled as i can to maximise cpu and ram availability. i dont even aply service packs. no need too. boinc doesnt care if xp has service packs or not. |

I still have a couple minor reservations about 7, but I may just decide to go with it anyway. Ha! I actually prefer Vista over XP and left everything at the defaults (minus a couple of minor preference changes). The one thing I don't like in Windows 7 is the fatter task bar. The Vista one seems slimmer and sexier. Someone else told me how to "put it on a diet" and make it thin again, so I'll probably do that immediately if I install Win7. The bug fixes and improvements are a definite plus, but the majority of them are to encourage XP users to switch while the current Vista users have very little reason to upgrade, other than those of us (like me!) that enjoy playing with the latest OS from MS. |

Ignoring all benchmarks, from any source, that you may have seen for those two dells. The RAC and total credits are about what I would expect for Seti. Apples and Oranges of the Same Size, Vista Home Premimum no Cuda Intel(R) Core(TM)2 Quad CPU Q8200 @ 2.33GHz [Intel64 Family 6 Model 23 Stepping 7] http://setiathome.berkeley.edu/show_host_detail.php?hostid=4789825 AMD Phenom(tm) 9550 Quad-Core Processor [AMD64 Family 16 Model 2 Stepping 3] http://setiathome.berkeley.edu/show_host_detail.php?hostid=4876058 Until the major portion of the outage hit they were running within a about 150 Credit/day of each other. The AMD had the advantage of a L3 cache of 2 meg while the L2 was 512/core. What makes it slightly slower is the Memory speed is at 1800MHZ (Norhtbridge) while the CPU is at 2.2Ghz (2200 mhz) so latency comes into play with various I/O functions which have to happen. So yes, it was fairly well proven that L2 Size matters as there are times that things get pushed out to RAM or Disk. @ Andy the AMD X2 6000 is still in Seti Beta... LOL Its Happy there...

I am running 6 BOINC projects on my Linux box using BOINC client 6.6.31, always as a user, never as root. The only problem I have is with graphics. Some graphics which used to work with BOINC 5.10.45 do not work with 6.6.31. Only Arecibo Binary Pulsar Search at Einstein@home gives me a good screensaver, so the problem is not with my Linux but with the apps. But screensavers are not useful and slow computations, so I do not mind. Tullio |

Doesn't Win 7 allow for installing in a folder of ones own choice? Or is that gone? Besides, Even though I could afford the $49.99 intro price(or $99.98 as I have 2 PCs), I'm saving up for a much larger goal, A larger house as I'm out of room here, among other reasons that is.

I still have a couple minor reservations about 7, but I may just decide to go with it anyway. Windows 7 gives a message "You can't directly upgrade from Windows XP to Windows 7. Go Online to learn how to use Windows Easy Transfer to install Windows 7 and keep your files and settings." Generally MS only allows upgrades from the version directly precedding the release.
