An OpenMM 5.2 version of Fahbench going to be released ? :mrgreen:

Unfortunately the FAHClient assigns a mixture of implicit and explicit assignments so core17 will continue to be "advanced" until it's reliable on both.

Please note that the posts regrading a custom benchmark run using WU Project: 7811 (Run 0, Clone 405, Gen 210) has been moved to its own thread here (viewtopic.php?f=38&t=25229).

These numbers are not unusual. However, testing was run on AMD CAT 13.11 Beta which supports the next generation of cards.

Hopefully this indicates a continuum of FOLDING support. :mrgreen:

Re: FAHBench (OpenMM 5.1) - HD7950 Boost / 13.9

Post by doesntmatter »

OS -> Windows7 64
GPU -> AMD HD 7950 Boost @stock (1000/1250 - Core/Memory)
Driver -> AMD Catalyst 13.9

(Compared to existing results)
OpenCL Explicit SP: 36.1814 ns/day - like a oced GTX 670 :D
OpenCL Implicit SP: 109.75 ns/day - between HD 7950 and GTX 760

OpenCL Explicit DP: 8.15148 ns/day - between GTX 570 and 580, far away from a HD 7970 :(
OpenCL Implicit DP: 16.166 ns/day - between HD 7950 and HD 7970

So far my intention to use FAHBench as performance check for correct drivers to run FAH did the job.

Question about processing Double Precision, usage of the GPU was dropping to ~64%, clock rate from Boost to base frequency (1000>900), does it slow down the result (which is o.k. in my opinion) ? I think it should be normal, part of calculating. But I wonder nethertheless, thought this Benchmark produces constant load on the GPU, as seen with Single Precision.

A reduction in frequency would slow down the result. Does the GPU Usage drop from ~99% to ~64% or does it stay at 64%? The variability of GPU Usage is a feature of FahCore_17 so it is expected but the drop is usually ~2% so not very noticeable on my GPUs (Nvidia Fermi and Keplers).

See detail from the screenshot above, calculation period before 82% of Double Precision:

The usage pattern is rather extreme for FahCore_17. However, I personally wouldn't worry about it too much since this occurs only with Double Precision. F@H uses only Single Precision (for both, CPU and GPU) so if they were any issues with Double Precision, it might be a low priority to fix.

Gigabyte GT430 back from RMA. Decided to run FAHBench on it :)
The GT430 was overclocked to 797 MHz GPU, 926 MHz memory. (Default clocks are 730 MHz GPU, 900 MHz memory)
Nvidia driver version WHQL 301.42.

Thanks for your results, I have updated the first post.

BTW, if you think that 1.1186 ns/day took long, image how it felt like with 000.243642 ns/day (AMD Opteron 185) :)

Double precision performance has never been a priority in consumer products. Business grade GPUs are better suited for DP processing but at a much higher cost.

Personally, I look at OpenCL Explicit Single Precision whenever I try to draw any parallels between FahBench performance and folding performance. FYI user123, my Avast antivirus Web Shield reports the image URLs in your posts as malicious. I'm 99.999% sure the following links are in fact OK, but better safe than sorry.

Well I can't find out if my GTX 260 c216 does support O CL 1.1 or not *shrug*, so seeing as no one's given a benchmark for this oldie I will ;).

Btw don't you want DP figures as well as SP? A lot of people seem to be posting SP only.
