You might look at the MD5CRK project, http://www.md5crk.com.  They have
some optimized clients for MD5, and SHA is pretty similar, isn't it?

See in particular http://www.md5crk.com/?sec=aboutmd5client which
indicates that their client will use the MMX and SSE units, as well as
dual processor systems.  It actually tries several different versions,
self-benchmarks them, and then chooses the fastest one.  I don't know
if they have source code available but if you explained your goals they
might be willing to help you out.
