I trust all of you guys here, but you might want to mention that those numbers are on unofficial - it's pretty easy to hack so we keep an official list on fahbench.com as well.

You can keep both the CUDA/OpenCL numbers, we care more about single precision perf. at this point. Don't really need double (though it is one area in which the K20 shines).

PS - does anyone have overclocked 580? That card is a BEAST.

I'll see about giving my 3 x 580SCs and 2 x 590 Classifieds a run on this either today or tomorrow.

EDIT 1: 1:30 PM EST January 19, 2013

FAHBench ran fine as far as I can tell.

Fascinating. How similar will they have to be? Exact same card? same family, or any two GPUs that meet base requirements?

I don't think he meant multiple cards working on the very same WU (like SLI or something).
Just multiple instances at the same time.

Posted: **Sun Jan 20, 2013 9:24 am**

no actually i do mean 2 cards working on the same WU - the problem is that kinda don't scale very well when testing internally (and they only work on explicit). I'll probably need to add another flag specifying explicit/implicit

I think you would have better luck running multiple WUs on the same GPU (utilization).
I believe some GPUs can allocate a certain amount of SPUs to different tasks.
Not sure about that...

Also, isn't there a bit of a problem with smaller proteins not scaling too well with more SPUs?

Posted: **Sun Jan 20, 2013 10:05 am**

Updated - 0.4 released, can now do multiple GPUs on same device.

"I think you would have better luck running multiple WUs on the same GPU (utilization)."

In FAH we highly prefer longer trajectories of a single simulation when possible.

That may be a bit of an understatement. I did a small check using CUDA and my 590s. Adding one gpu increased the performance by about 33%, adding a third gpu increased the performance about another 25% of the original score, and then a fourth showed no improvement over three. This was done on the same 590s I posted about in the other thread (linked above), but I had a couple of additional things running that may have reduced scores from yesterday. I will have to run this again when I have nothing else to do on this computer to see if the reduction seen on a single gpu from yesterday to today was because of other processes or the change from v0.3 to v0.4.

Unfortunately yes. The CUDA platform does a lot of JIT compilation and hence requires the nvcc compiler. We assume the user has the NVIDIA GPU COMPUTING TOOLKIT 5.0 installed (and hence why its able to find CUFF).

proteneer wrote:Updated the download with some additional libraries - please redownload. Should fix OpenMMOpenCL.dll errors.

Did this ever get resolved? I have 0.4 and without installing the toolkit I ran the http://www.dependencywalker on the OpenMMOpenCL.dll file that came with the benchmark. I don't know if you're still interested in the results.

Code: Select all

Error: At least one required implicit or forwarded dependency was not found.
Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module.
Error: Modules with different CPU types were found.
Warning: At least one delay-load dependency module was not found.
Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module.

Three files could not be found:
CUFFT32_50-35.DLL
MVSCR90.DLL
IESHIMS.DLL

I'm not sure if you ever want to make FAHBench download all it's dependencies, but if you do, I though this might help.

I'll install the toolkit now.
