EETimes reports here that there is $50K associated…

Hmm, that seems great! I think it is pretty informative. We need know more things about this stuff!
Speaking of OpenCL, AMD, again, is said to release a book on OpenCL… I bet that’ll make coder’s life significantly easier:

(BTW: I don’t have any particular allegiance to AMD, I run AMD and Intel systems and am happy with both).
