Shared memory only, yes. Many, many people skip OpenMP completely and go pure MPI. From a coding standpoint it's far easier to multiprocess using one technique rather than two, and the performance gains for using both tend to be marginal or non-existent -- at least in my experience. There was a long discussion a while back on the list about the pros and cons of each approach. _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
