1) Message boards : Number crunching : How do I run GPU high priority and other questions. (Message 1469758)

Post:
just curious @batterup why you don't want to use the lunatics installer - i also do not know anything about coding but the installer for the optimized app also creates an "app_info" file which you can easily edit to control the number of WU's on each card in addition to being able to change GPU priority (I think the "avgcpus" lines of code, found above the "<count>x</count>" sections is responsible for that - I haven't edited the priority myself though).
You are working with some amazing equipment and lunatics definitely increases your RAC a bit.
By the way, your "fly" signature gets me every time

i would grab the .41 installer from http://lunatics.kwsn.net/ and just watch your CPU/GPU temps and utilization if you are worried it is going to over-stress your box

With 780ti the sweet spot seems to be 2 WU's per GPU. As long as I leave my fans on full speed, I can crunch on 7(virtual) cores and leave 1 core free to help the GPU. If I don't want to have my fans (10 x 140mm) up all the way, I only keep 5 cores crunching, which keeps the temperature down. And yes haswell is definitely hot. I have mine OC'd to 4500MHz and even with my water cooling and 240mm radiator and gigantic case, the CPU temperature is 70 Celsius. If I didn't have all these resources dedicating to cooling the CPU it would be like 95 Celsius.
If you are running 3 or more WU's, load up GPU-Z and drop the number of WU down to 2 and see if you are running near 100% GPU load with the one less WU. Basically you want to have the lower number of WU's running that gets near 100% GPU load otherwise the extra WU's arent doing any benefit.

Yes I think I will leave it at this setting right now, see how it pans out over a longer period of time. Can always tune it again. Interestingly enough, my dual core systems with GT430's seem to work best while using only one core to crunch, and then running 3 WU's on the GT 430 simultaneously. On that system, the GT430 GPU load is around 85%-90% and uses about 775MB (1GB GPU). Of course it gets through the units wayyyyy slower, but I don't know enough about how this technology works to understand why 3 WU's dont max the load on a GT430 while 3 WU's max out load on a GTX780ti.
Thank you guys for your input :)

I lowered the GPU WU's to 3 (.33) and the CPU usage option in the BOINC setting to 62.5% (5 of 8 cores - virtual included). GPU load still steady around 97% and temp around 82 Celsius. I suppose I can take this to mean that 4 WU's was definitely overkill and past point of diminishing returns?
CPU cores showing ever changing loads across all 4 cores I can see in "CoreTemp1.0" and temperatures in the mid 50's Celsius, on average.

Hello everyone, just finished building my dream machine, I am currently running one GTX 780ti (EVGA superclocked - but the one with the stock fan, NOT the custom fans)with the i7-4770k and 16gb of 2400 ram. CPU is water cooled with a seidon 240m. I will eventually add a second GPU for SLI but that is months down the road.
I have modified my lunatics app_info to run 4 GPU work units simultaneously (in addition to the 8 CPU WU's BOINC automatically runs) so I have a total of 12 WU's going at a time. I just started running BOINC on this machine today and CPU core temps are around 50-61 degrees Celsius. GPU-Z shows my GPU is running at about 81 degrees Celsius using about 1333MB of memory and a GPU load of around 96-97% with the GPU running 4 work units (.25 in the app_info <count> lines).

Considering the cost of this hardware, I obviously don't want to damage it or overdo things.
I would appreciate any feedback on this subject if anyone who knows more about these things has any pointers or thinks I should do it differently. Thanks in advance!

Hey guys, reading this thread sounds like a foreign language to me, but from what I gather, are we supposed to drop the binary into the setiathome.berkeley.edu directory, and in the app_info change the line:

<name>ap_6.01r557_SSE2_331_AVX.exe</name>

to

<name>AP6_win_x86_SSE2_OpenCL_NV_r1316.exe</name>

in the 2 places it is referenced?

I am just humbly trying to learn from you guys, but if I am wrong and there is actually a lot more to it than just that, I can wait for the next installer release and just do it the simple way without modifying the app info or anything?
btw, thanks for your hard work on these improvements.

Wembly: yes since pretty much september of 2011 when gold topped out over $1900 gold and silver have been in what we call a "D wave correction" - it is normal and healthy after the 2 1/2 year "c wave" advance that preceded it, which took gold from around $800 to $1900. So we went up over 100% in the 3 years prior, then we take a little less than a year to correct from 1900 to about 1600 (not a very large correction percentage wise, but stagnant as far as making gains for the whole time period).
It is during these pullbacks like the one we have been seeing since september 2011 that people like myself do the buying and loading up, and it is during the c wave advances that we sell and take profits. healthy assets that are trending upwards move in a "3 steps up, 1 step down, 2 steps up, 1 step down, 3 steps up..." kind of pattern. so when you post a 1 year chart like you have, it is not telling the whole story. even if you weren't to take profits during the rally, had you bought in 2007-2010 as my clients and i have been doing, you would still be in very large profits even in the context of this pullback. and since we offloaded the majority of our position in april of 2011 (a good few months before gold topped out- so we didn't get out at exactly the top but clearly made out very well considering our early entries), we have had the cash to be re-loading our gold and silver positions from December 2011 through the present, as we are currently still adding to our positions at these levels.
Once the next round of quantitive easing/stimulus or whatever they want to call the next round of money printing and debasement begins (likely before the election in an attempt to inflate stock prices and make obama look good) you will see gold begin its next c wave advance (sharp rally).
Lastly, the US dollar has been relatively stronger over the past few months thanks to an exceptionally weak Euro, and since the US dollar moves inversely to asset price measured in us dollars, gold and oil for example appear lower when measured in a stronger US dollar, but in terms of other currencies is at or near all time highs. that high price is raising real demand and therfore putting a floor on gold prices just above $1500 at the moment, even in dollars. bottom line: given the catalyst, which is keynsian federal reserve and ECB bankers continuosly printing money in order to attempt to fix problems that they in reality are only making worse, will give you higher commodity prices all across the board in the near future. most importantly, oil and food prices, which when they get high enough will push the world economy further into the abyss. all the while wealthy people who are in the know are moving their wealth out of cash with its record low interest rates, and into real assets like real estate, gold, and stocks which are gaining value while the dishonest tax of currency devaluation steals the purchasing power from cash holders.
those most at risk are retirees, pensioners, and those on fixed incomes or those who aren't getting a raise. the reason they are worst off is because while their income stays the same, the prices of the things they need to buy to survive are rising thanks to inflation (currently inflation isn't that bad, you haven't seen nothing yet if you think it is bad right now).
so investment in real assets, for example gold, helps protect savings from inflation because the value of the gold rises with inflation, versus the dollar/euro. if you were to put aside an ounce of gold, and the $1600 it costs in us dollars presently, and in 3-5 years take that $1600 and that ounce of gold and try to buy some gas or food, you will more than likely find that the ounce of gold will buy you more gas or food than the $1600 will.
I apologize if my thoughts weren't neatly organized as i just let them flow from my head to my fingertips, but i hope this helps you to better understand what I was saying earlier.

EDIT: here is a chart of gold over 10 years, notice the chart wembly posted is only the most recent downtrend within the overall larger picture.

Frizz I couldn't agree with you more :)

Your words are pretty much exactly the same as the ones out of my mouth each day as I implore my clients to trade in their dollar and Euros for shares in gold, silver mining, and oil producing companies as well as ETF's that hold physical gold and silver. Those who listened to me are sitting pretty, unfortunately many are still too paralyzed with distrust and fear of the markets and investments so they under-invest, and those who I am pursuing as new business shrug it off and force me to call them back 3 months later to rub in their face how they missed out on a 60% gain in just a few months time. Personally I don't keep a savings account, I only use my checking account for medium term cash needs and check writing purposes. My savings account is in silver bars, american eagle and canadian maple coins, and a little bit of physical gold as well. (i believe silver will outperform gold tremendously over this decade and so far it has proved true, i am also young and willing to take the extra risk as silver is far more volatile compared to gold, so I am personally leaning much heavier in silver). sorry to get all financial lol

I'll be intersted to see how long bitcoins stay around and where their value goes in comparison to dollars, gold, euros, etc..

oh yea and another reason i figured I wouldn't even bother with this is that only AMD cards seem to be worth the time. even top of the line NVIDIA cards dont compete with lower end AMD for the bitcoin tasks...I will stick with buying NVIDIA cuda cards for crunching SETI.

I have a reasonable BOINC balance (600M) and have been doing bitcoin related stuff for the last year. Mining pays for all my electricity, my house is noce and warm and it keeps my CPU projects running quite happily. In addition, there is real money involved and despite the bad comments here, ignorance isn't universal.


Thanks for sharing patrick, first good thing I've heard so far. Approximately how many hours a week do you "mine"? Is it with that one computer i see on your computer list here (or rather the GPU on that machine since as I understand it, bitcoin mining only works off your GPU(s)? How many bitcoins do you earn in that time?

If you use your bitcoins to pay for your electric bill, it sounds like you must be making a few hundred a month with bitcoin- you haven't found that it eats up more electricity than it pays for? That is one of the main arguments I seem to hear. Like I mentioned before, I just wanted to run the bitcoin miner long enough to earn enough bitcoins to purchase some new hardware for my dedicated SETI boxes, so that was the only return I was hoping for.

Got it guys, thanks for the info. I knew I felt like I was missing something when I first read and watched videos about it.. Electricity cost is higher than the value of the bitcoin then that makes it pointless right there. I must admit though, as a professional commodity trader/investment banker/stock broker, following currency fluctuations by the minute is one of the main things I look at to navigate my clients money safely- and I was intrigued by the idea of this so called project that is creating an alternative currency. I specialize in gold, silver and oil investments and as all western currencies are being aggressively undervalued day by day, I have done extremely well by pouring capital into gold, silver, and oil at the right timing of course. Bitcoins sound like they were conceived to be another alternative currency, something I strongly believe in these days from an investment standpoint. But as many of you have pointed out, it is extremely flawed, unprofitable, and likely unsafe. I'll keep my eggs in gold and silver coins/bars/stocks and continue to stick with what I know. I wasn't looking to make myself a return with the bit coins, I was just trying to be clever and use my existing crunching infrastructure to finance more hardware for SETI. Oh well- I guess you can't get something for nothing after all :)

Forgive me for bringing up another sort of DC project, but for my potential application it would benefit SETI.

I have been aware of the phenomenon that is "bitcoin mining" for a few months now. It seems to have been a profitable venture especially for those who began mining early on. It is apparently so profitable that some people have set up "bitcoin farms" in much the same way that some of us (myself included) have set up SETI crunching farms.

I would like to be able to add GPU's to my SETI rigs as often as possible, and I am also hoping to build a monster cruncher as soon as possible. High end GPU's are clearly quite expensive, and since the crunching infrastructure is already in place for myself and others, I have thought perhaps dedicating some time to bitcoin mining in order to exchange those bitcoins for hardware. I have found that some sites will sell you a GTX 680/690 for a certain amount of bitcoins. As I plan on putting multiple GTX 690's in my new rig, I thought perhaps this might be a creative way of financing at least a portion of this rig and upgrading GPU's in my existing Seti rigs.

If anybody has any experience with bitcoin mining, would you please share your thoughts? I have no indication of how many dollars worth of bitcoins I could mine in a given amount of time with my current hardware, but if any of you know it to be lucrative or fast enough, I might give it a shot.

I hate to take my rigs away from crunching SETI WU's for even a moment, but as they say, sometimes you have to take 1 step back to take 2 steps forward- in the longrun this would greatly increase my SETI output if it actually affords me some decent hardware without me having to go into my currently sparse pockets. I haven't decided for sure if I'm going to do it yet, I first want to get a rough estimate of how productive my rigs (all the ones on my computer list here on S@H) will be, if it doesn't seem worth it then I won't them off of crunching at all and I'll just continue to come out of pocket for this project.

Looking forward to hearing your thoughts.

I am confused and full of joy at the same time.
I'm assuming correctly that Lunatics provides optimized applications for setiathome_enchanced 6.10 cuda_fermi processing? Because I'm happy to announce that these don't crash. :D


yes the lunatics installer .41 has all the programs built into it, and it considerably speeds up the rate at which WU's are completed. you cannot use the seti screensaver though if you are running the lunatics app, just FYI.

there is a thread on this number crunching board that is titled "lunatics installer release notes" or something like that, you should find it helpful.

that is a pretty sweet rig you've got toby, the gtx 680 with lunatics app is probably the most punch packed by any crunching device, other than a gtx 690 (which is essentially 2 of your 680's)- i hope you get it fixed soon!

Posted 25 Jun 2012 by Profile Yanivicious
Post:
Ive used 2 9500GT 512Mb on a host in which later Ive installed a GT430 1Gb.
The RAC crunching 2 WUs in the GT430 (around 15K using 8 CPU Cores) was bigger than the RAC crunching 1WU in each GT9500 (around 12K also using all the CPU cores)...

Now, the GT430 is in a low profile case with a standard 300W PSU (of unknown brand) that is also feeding an I7-2600, 1 old HDD and a DVDRW drive. Ive not seen any downclock and is keeping a steady RAC that is never uder 15K.

At the time Ive bought the GT430 the only other option for Low Profile / Low Power GPU was the GT 520, which was just a 5% cheaper but with half the cuda cores and less clock speed...

Ive not found a good replace option in the new 600 series for a low profile GPU. I think the GT640 (wich in Zotac page says it needs a 350W PSU) its the only one of the "cheap" cards that is worth its value for crunching (but it is not low profile).
Any GPU under the 640 is more expensive than the 430 and it seems they are no better in performance judging by the number of cuda cores and the clock speeds...



horacio: can you clarify what you think your approximate RAC from your GT 430's was, as i understand you were running 8 CPU cores contributing to the 15,000 RAC. I am currently running 3 systems with GT 430's, the c2d 7500 and 4500 are dedicated seti boxes and run 24/7 with both cpu cores and 2 WU at a time on the GPU, and the c2d 5300 is running almost 24 hours, it only suspends crunching when computer is being used and resumes after 2 minutes of idle, so i'd say 22-23 hours a day that one is crunching with also 2 cpu cores and 2 GPU wu's. my RAC on those systems as you can see is around 5k-5.5k on the 4500 and 5300, and around 7k on the 7500. wondering if other people running those cards are having similar experience.

and regarding wembly's question, i think u made the right choice with the gt 440 all things considered, assuming u are working with a limited PSU as i am on those 3 systems (only reason i'm not running something more powerful on those systems, would much rather have a gtx 550 or 560 in those if the PSU's could handle it).
