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).

Oops.  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
