Claudio,

I just committed an OpenCL Office 2013 format, using your SHA-512 (but optimised for loop use). It works fine on nvidias and CPU but fails self-test on HD7970. I think the code is fine so it may be some kind of driver bug that has to be worked around. If you have some spare time, please have a look.

BTW it does around 44 million SHA-2 per second on the 570 and over 75 million on HD7970. Are those speeds fair or lousy? There is a huge need for private memory so I have no idea how to get it faster.
