I'm getting ~5 ms/it with a 580 now, and that's without tweaking the FFT. That doesn't seem very exciting . I hope the nVidia Titans are not the same as a 580 for CUDA work. Especially since they are going to cost $899 US.

Do you have a K20X or access to one?

Wrong tread, this is mfaktO. I suspect some mod moved them here, as the discussion is not connected, too.

YMMV, but on my Asus AMD board, if I run the chipset driver install with the ATI iGPU disabled in BIOS, the ATI graphics driver is not an available option.

EDIT: All my graphics and crunching run on nVidia. I have, however, been able to run graphics on the ATI iGPU in combination with crunching on a GTX 460. I doubt that the HD49xx (don't remember exactly) iGPU has the cojones to run mfakto. The problem for using it for display, is that I then loose the discreet GPU processing power for Photoshop/Bridge. Hence, I don't use it at all.

Brilliant, thanks a lot for these tests!

  • The first test (running on the CPU) shows that even without the AMD SDK, mfakto can compile the kernels, but they don't work with the Intel compiler (no factor found).
  • After installing the AMD SDK (as part of Catalyst), you need to force mfakto to use the Intel platform (mfakto w/o -d switch did not find anything)
  • Now the CPU device is missing, instead the HD4000 is available as the only usable device, but it supports less features (no surprise here). The -35 error is CL_INVALID_QUEUE_PROPERTIES - I can remove my request for out-of-order processing on the device, that should get around this error.
  • Compilation of my OpenCL sources does not automatically propagate constants to vectors - I can change that in the code. And it does not know about printf - easy as well.
I think I can provide a version of mfakto soon that solves these issues, I just don't have time right now ... and then we may face the not-working kernels problem again, this time on the GPU. And this one will be harder to tackle.

Bdot,

Thank you very much for continuing to follow up on this frustrating issue!

The iGPU of the AMD APUs is capable of running mfakto and delivers ~30GHz-days/day (HD 6550D / A8 3850). You should not try the older iGPUs. Though anything HD4xxx and higher will work, you may end up with 3 or 5 GHz-days/day.

I made the changes and created a special hd4000 package. Would you give it a try? I hope I caught all the compile errors.

The mfakto.hd4000.exe binary is the ordinary one, if that succeeds compiling the kernels with the -d 11 switch, then you can try 'mfakto.hd4000-pi.exe - d 11 -st' in order to get detailed performance numbers for the different kernels.

Hi Bdot,

I take it that that hd4000 package is intended specifically for sdbardwick to try on his machine, is that right?

Yes. And for others who see the HD4000 in the clinfo output and have the ADM SDK as well as the Intel SDK installed.

A bit different here.
Running two instances on integrated (6550D) to max it.
