It is a good path to follow, but I saw a lot of errors in raw formats, 
event MD4 and MD5. And it doesn't make sense, "they are very simple code".

Intel OpenCL driver/compiler creativity!?!?!

That said, seems to me OpenCL and MIC are not going to be a production 
quality target for a while. I might solve the problem with raw formats, 
but I'm not confident things are going to be much better than now.
