[Beowulf] Picking a processor

Hi

I think you'll find at least the beginning of what you want on the 
Top500 site (you have found that haven't you ?).  Many of the results 
reported there are measured in Gflops.

For theoretical performance figures the processor manufacturers 
web-sites are usually informative.
