I play with SGE & OpenPBS, but not PBSPro (don't have the $$$), correct
me if I say anything wrong about it.

I asked a stupid question on the PBS users list before: "Is there an
OpenPBS developer list??"

I did not get any answer. The problem is that PBSPro is also
opensource, so in theory if outside developers have access to the
OpenPBS cvs tree, they can patch OpenPBS with PBSPro...

experience with LSF, so other people may spend more time, but the

Actually, there are more traffic on the PBS mailing-list...

I think PBS is still more popular in research labs and universities,
where people tend to be more active in mailing-lists. SGE, on the other
hand, has more commerical (EDA, bio-tech, etc) users.

But if you analyze the traffic on the PBS mailing-list, you will find
that a lot of messages are related to installation, compile problem, or
jobs don't get scheduled. PBS does not work "out of the box".

And don't abandon star-office, I don't want to stick with M$-office.
