Sorry, I don't understand what you mean by "OpenCL much architecture neutral" (as well as what this has to do with your CUDA patches). > It was just quick draft of fast MSCash not slow MSCash2, so I didn't > spend much time on that and renaming is not needed.

I was so sure that you'd work on MSCash2 rather than MSCash that I didn't realize the patch was in fact for the latter. Yes, you listed "20671K c/s", which is 20M. So, we need MSCash2 and something like 20k c/s instead. ;-) Just why did you start working on fast MSCash? I think this was never planned to be part of your work for this summer. Instead, you have MSCash2 and OpenCL stuff to work on (and also making your other/older slow hash patches more reliable/portable/faster). Thanks, Alexander
