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. =)

Hi Jenny:
Just throwing in my 2 cents here.
If you are new to batch scheduling systems and you don't have a preference, I would recommend using something like Torque or SGE (instead of OpenPBS). OpenPBS is no longer being maintained and there are much better choices out there.
Cheers,
Bernard

Hi Michael,
Wow, thanks for the quick response. =) Yeah, please don't break your production cluster just to check this out. I will look at the installer again to see if I see that check box you're talking about. It actually sounds really familiar. I installed an OSCAR cluster about 3 years ago and I think I remember seeing that then but I can't seem to find it now. I did try defining the master nodes private interface as node0.cluster using the install_server GUI with horrific results. Yeah, I won't try that again. It completely broke my access to the oda database so I couldn't back out of the installation or fix it. I spent quite a bit of time trying differen things like granting access to the [EMAIL PROTECTED] user but it still wouldn't work so I finally just threw my hands up and rebuilt the system. =P
As for just geting mpich to work on its own, it appears that it is configured correctly after the OSCAR installation so that isn't really a huge problem. Well, except for the fact that it is only seeing one processor for use. If you have any idea why that is happening please let me know. I would really like to have all the management stuff working though which is why I'm still pushing to try and get the xpbs stuff setup correctly. If you have any other ideas for me, that would be great. Thanks Michael.
