(registration required) NAS parallel OpenMP vs NAS Parallel MPI on clovertown node (dual socket, 8 cores total). As Greg said, the programs are different but, I suppose it is better than nothing. I should mention that such comparisons are hard because a good shared memory version of an algorithm and an MPI version of the same problem are usually very different. If you can find a copy, Pfister's "In Search of Clusters" devotes a whole chapter to this topic (in detail). -- Doug > Hi there, > > Is there such a benchmark that I can refer to?
