if i am correct, openCL is extension that only works on gpu, .
cpu dont need that extension because it nativly supports all operations.
if you want gpu to make calculations, then you will eed openCL Smiley
so cpu and openCL ? wtf ... nooo Smiley

If I understand Intel correctly it does appear that you can run OpenCL on Intel® Core™ Processors.  It might be an interesting project but I wouldn't bet on it beating a GPU, that is unless you had a server farm and a wad of cash for power.

Good luck trying to beat cpuminer when you are hindered by an extra abstraction layer and can't use assembly instructions directly Smiley

I agree. Also a GPU will always be faster, unless you have something like a Xeon Phi.

There's no reason to force a choice between CPU and GPU and opencl is likely the best choice for scheduling and partitioning the work.  A couple CPU cores could be used to pre-initialize the initial work state before being queued for hashing in a GPU command queue.  If it's a CPU-only kernel, you can still make use of calls to inline-assembly in the host program for the opencl kernel(s) if you want (and can do better than SSEx optimization).  Have fun with it.
