Prime 95, Linpack, SuperPi type program for GPU?

[unixguru88]

Furmark seems to be the most popular stress test for GPUs, but now that OpenCL and GPU computing seems to be in thing, shouldn't there be similar programs to error check our GPUs? Is it possible to "port" the ones mentioned in the subject to OpenCL, or at least write similar ones?

Kombuster/furmark are good for stressing and such but they can kill cards. Also running 3dmark06/11 will also show you quickly if your card is unstable.

This type of program is not what I had in mind. Kombuster/furmark and the like are got for stability testing, but I want an error checker. Suppose, I am using my 6950 unlocked for scientific computing, I need to be sure that there is no error in the computation. Something like Prime 95, Linpack, SuperPI, can detect errors.

I could apss hours of ATI Tool and furmark but then fail when running the Crysis benchmark.

Always stress test with real games as these stress test programs don't use the complex code that games use and thus don't stress the whole of the GPU core.

If you can get through 10 runs of the Crysis benchmark then your stable.

My personal favourite software to verify reliability of a graphics card (especially for GPGPU) would be the folding@home gpu client. You'll need to make sure you never see a single "NaN dected" error throughout a 24-hour continuous run.

Keep in mind that folding@home gpu client cannot stress the card(s) with highest power consumption. Furmark is still the ideal software stress testing AMD cards.

THank you! This is the type of program I had in mind. I will try it out. Kind of surprising that there are not many programs for error checking. Does anyone whether the bitcoin miners can be used for my task? It seems to be stressing my GPU quite a bit.

Again for previous posters, my aim is not stability testing, but rather error checking. Situations might arise when the GPU seems to run stable, but there are still errors. On the CPU side, I have observed that when I overclock beyond 3.8 Ghz. on my Phenom II, almost everything seems to run perfectly, but I get an error in Prime95 usually before 15 mins. I want to ensure that a similar thing is not happening on my GPU.
