I really like nvidia, they have stable drivers and much less problems with everything. It's just the little problem that they suck at password cracking and that's not really about CUDA vs OpenCL but hardware differences. However iirc when it comes to 64-bit formats, nvidia may look better - or at least less bad. > Regarding the Nvidia vs AMD comparison, 2 of the world's most powerful > supercomputers consists of Nvidia devices where as there isn't any AMD > machine in it (http://www.top500.org/lists/2013/11/).

I can't find it in the list you link to, so maybe it was some other top 500. > I, personally would say to keep the CUDA support open.

BTW apart from wpapsk, CUDA md5crypt also lags behind the OpenCL version. Feel free to fix that. Either have a look at latest md5crypt-opencl in bleeding-jumbo, or do it on your own and make it even better. magnum
