InfiniPath MPI has always optimized this. Of course, there's no way it can read your mind and know if you are going to run a second 4-core job on the same node, so there is no perfect default. But it has switches to give you either behavior, tightly packed or spread out. -- greg _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
