While true, I ran openpbs and pbs pro (via a free to .edu program) and they were both terrible. I talked to other users, support forums, and related and found many with the same story. Instead of playing the apply random patch from 3rd parties game I switched batch queues. Granted this was 5+ years ago, I assume things are better now, and have heard quite a few good things about torque lately. SGE does seem the default for many small/medium clusters these days (and is the Rocks default) but does make some things strangely hard, usually with a work around though. In particular I find the lack of a straight forward way to handle requesting nodes and processors per node strange. _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
