Oh, that's great news. I was going to check to see if the opd would
list Torque or SGE but you answered that for me. Before I sent off
my last e-mail saying that configuring the master as a client through
the install_server GUI killed my setup, I tried it again since I've
learned a lot since I last tried that and sure enough it did the same
thing again. Doh! So I'm currently in the process of rebuilding
that machine again but I'll try installing Torque after I've got it
up again and see how that works. I just saw Arnie's post and he
seems to be happy with SGE so I can try that too. I hope there are
no issues with having several schedulers installed. I would turn the
daemons off for the others but still. Ok, well it looks like my
system just finished kickstarting so I'm gonna try this again.
Thanks for all the info.

Hi Jenny:
I believe PBS Pro is free for educational uses, so perhaps you guys can
get it for free.
Torque is basically OpenPBS but with it all patched up (and updated
quite regularly too).
Sun Grid Engine is getting more and more popular (and my personal
preference).
You can actually d/l and install Torque from OPD (OSCAR Package
Downloader). I am working on creating a package for SGE as well but
that has been pre-empted by other projects I am working on.
Cheers,
Bernard

Hi Bernard,
That is good input. I went to their site to try and get some
documentation and it looked like OpenPBS is no longer so
Open. =( Professional PBS appears to be what they're
throwing their effort behind now. I'll check out the other
batch schedulers you suggested.
I can still use my same infrastructure that was setup with
OSCAR and just use cexec or something to push out the new
scheduler to the other nodes...once I have them. Thanks for
the feedback. =)
