If you are having difficulty getting openmpi set up yourself, you
might look into OSCAR or Rocks, they make setting up your cluster much

reducing your management overhead.
I can help you (off list) get set up with OSCAR if you

If your problem size is not large enough than any MPI program will
perform worse on a "large number" of nodes because of the overhead
