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.
