I figured I should post my prpclient genefercuda experience in case it is helpful to the authors or anyone else.

Running great on Win 95 32-bit on a GTX 460. Genefercuda uses a full CPU core for under a minute and then nicely fully loads the GPU and uses virtually no CPU time.

Running not as great on Win 7 64-bit on a GTS 450. Genefercuda uses a full CPU core for under a minute and then nicely fully loads the GPU but continues to use CPU time. The CPU time it uses cycles between a fully loaded core, partially loaded core, and then no load on the CPU. The second time prpclient was run it was immediately shut down and quaratined by Norton Internet Security 2010 SONAR. I jumped through some hoops to get it back and then it ran okay again.

In both cases I was using this version: prpclient-4.3.0beta-windows-gpu.7z and NVIDIA driver 266.58.

The GTS 450 has 192 CUDA cores instead of 336 (like the 460). Also, even though it is clocked higher, it is essentially a much slower card.

Thus it takes more CPU time to keep it fed. At least, I think that could be the issue. The GTS 450 is a good middle- to low-end CUDA crunching card but good for other, less stressful applications. Given that GeneferCUDA requires a double-precision GPU, and the GTS 450 is a lower-end and slightly less "capable" DP card, it's not that surprising that it takes a bit more CPU time (and I'd imagine more runtime in general) to complete a task.

Now the part I can't explain. The test counts for GFN262144.

The prpclient.log file on the Win 95 32-bit GTX 460 machine says:
Time: 74:31:52 Tests: 6
(although it looks like the count is wrong because it appears to have done 10 tests)

The prpclient.log file on the Win 7 64-bit GTS 450 machine says:
Time: 91:52:03 Tests: 39

The GTX 460 is supposed to be more powerful than the GTS 450. The rest of the hardware is similar except that the 64-bit machine has 8GB RAM and the 32-bit machine has 4GB RAM.

Any ideas?

Thanks,

Rick

What should there be similar? How got you any cuda running on Win95?
IIRC, Win95 got troubles with more than 512MB RAM...

Oops. That's Win XP with SP3 32-bit not Win 95.

People must have wondered.
