A while ago I wrote a CUDA implementation of a subset of the Memtest86+
algorithms,to test the reliability of the consumer GPUs used by our
distributed computing project, GPUGRID. You can get them here:
That said, we never really used it in anger (most of the stability
problems we were having turned out to be due to 'factory-overclocked'
GPUs) so YMMV.
