Subject: MPI-openCL build; fast hashes are faster!!

Hi ,

OpenCL-MPI build using openmpi results in some of the fast hashes to speed
up by 1.5-3x without any extra modification  e.g. raw-md4,raw-md5,raw-sha1
,xsha512 and des. I haven't tested all hashes but most of them works fine
except the slow hashes which causes asic hangs most of the time with
anything more than 1 thread feeding the GPU.


PS: OpenCL 1.1 or higher required
