Re: Graphics Card Performance

On my 7970, usage never goes above 68% and WU setup/teardown periods are really long, 2 to 4 minutes of nothing for 1 min of crunching, anybody else notice that ?

Exact ref is Asus Matrix HD 7970 Platinum.

Edit: I should add that the same was happening with 2x HD 5850 but I wasn't really concerned since they were each taking 4 minutes per WU when the 7970 takes a minute or less, it now feels like a waste of seconds ^^.


The first question is: do you use app_info.xml file? http://www.worldcommunitygrid.org/forums/wcg/viewthread_thread,34225_offset,20

You can find lot of info here about it, just search for app_info or app AND info AND xml - it could improve utilization of your impressive GPU.

Cheers and NI!

Re: Graphics Card Performance

Ty Hyper, very informative breakdown.

I have heard that with NV upper end 5XX and 6XX 2 GPU per is the sweeter spot and almost doubles the 1 per output. Have you tried that? It would also avail more CPU cores to CPU only projects.... If you can get that to work. As it seems you have.

Just food for thought.



You are perfectly right. With 2 GPU on the GTX 680 and 10 CPU threads the daily WU creep up to 616 instead of 550. Over 10% improvement. The GTX 580 behaves similarely except that the num bers are higher, this due to the different architecture between the 680 and 580.

I must say that for a company like Nvidia that targets supercomputers, parallel computing etc. it is an extreme disappointment for their performance in WCG.

We are not talking small change here. The top ATI board is 6 times (600%) more powerful than the top Nvidia board.

Cm'on Nvidia wake up!!!!!


I tested the GTX 580 and the behavior is surprising. As a reminder CPU is 980X running at 4.0GHZ with Win 7 64bit and ram 6GB running at 1600Mhz. Boinc is version 7.0.28 64bit

With 2 GPU + 10 CPU I get 824 WU / day
With 4 GPU + 8 CPU I get 972 WU/day
With 6 GPU + 6 CPU I get 955 WU/day reduces a bit
With 10 GPU + 2CPU I get 1090 WU/day maximum performance yet and a little above to the HD 7970 with 1 GPU+ 11 CPU.

The multiple thread GTX 580 can beat the stock monothread HD 7970. Wow my GTX boards are not fully dead yet. wink

Interesting scaling effect. I will have to try 12 GPU and no CPU. Stay tuned.

Re: Graphics Card Performance

I think the use of various modified configuration file for graphics cards is something like cheating .. Or then wcg cell cheating cheating us who are not using something like that ..? ....
Cooperation between the creators and developers in wcg graphics card should be more.

As long as the actual output (in number of completed workunits) increases by modifying config files, it's no cheating to me. Actually it seems to be better to modify the config files so the graphics cards can be utilized more efficiently.
When the output remains the same and there is an artificial increase in points, then of course I think it's cheating.

Go to http://translate.google.com and translate words "cheating", "cheating" and "cheating" into you own language. Than think about the meaning of them in your own language.

And after few years of thinking, if you will still be sure that people who invested thousands of Dollars or Euros or whatever currency into computers which they (we) are dedicating exclusively for free-of-charge-crunching in the projects like WCG are cheaters, feel free to come back here and we can finish this discussion.

Cheers.

Is it cheating when folks OC their computers to get the regular wu's completed faster? I don't think so. The GPU just accelerated the completion time since GPU's are allot more powerful than a CPU. Anyone with a compatible card can run at least 1. The app file just lets use take advantage of the power of the GPU. Look at the top 100 super computers. They didn't get there on CPU alone. They are using a combination. I suspect GPU computing is the future of grid computing. More and more projects are moving towards that way. Cheaper too.

Re: Graphics Card Performance

[SOT]I really do not understand such crying hypnotized . If somebody has enough money to build 2x i7-3930K CPU @ 3.20GHz + 2x i7 CPU 920 @ 2.67GHz rigs/computers (http://boincstats.com/en/stats/15/host/list/0/0/822149) and has enough money to pay electricity bills especially for two 3930K's, one powerful 79xx (or 2) would not be an issue for him/her. And with it (them, GPU's) (s)he can also use app_info file or whatever (s)he want to accelerate his/her shrubbing performances[/SOT]

FWIW The problem with Nvidia on projects like this is their poor driver support for OpenCl. Until that improves they will continue to eat ATI dust. Does Nvidia have plans to improve on this?

Re: Graphics Card Performance

it's not about racing, but collecting points and badges is fun and stimulating. I understand your frustration for PC hardware, it is not easy for most of us, even me also.For me it is important to make the most help cancer research.We can put a new post from the title gpu chart for the convenience of people who go to such. buy new hardware. but that's probably not necessary. An emerging issue is scaling the company products nvidia. Some are good in fps in games, but I'm still waiting for kepler powerful in calculating. http://www.anandtech.com/show/6421/inside-the...and-186k-nvidia-gpu-cores. But I do hope is that -http://www.xbitlabs.com/news/cpu/display/2012...r_for_Supercomputers.html. phi is a big breakthrough in this segment and if people prepare an effective role for the xeon, it will interesting ...

I bet nVidia would respond with something like: Cm'on WCG, make an HCC-CUDA-WUs at WCG; you're making nVidia eat ATI dust!!! ...

FWIW The problem with Nvidia on projects like this is their poor driver support for OpenCl. Until that improves they will continue to eat ATI dust. Does Nvidia have plans to improve on this?
... to which WCG might respond with something like: Cm'on nVidia, stop crippling your good-for-games-only consumer GPU-cards; bring OpenCL to those cards then we may consider CUDA specially for nVidia. For the meantime, ATI dust-not taste that bad, dust it? laughing
