I'm hoping that someone here knows a little about PBS...

It used to be that when I submitted a job on my cluster using the 'qsub' command I would have to use the fully qualified domain name to submit it to a selected node like:

qsub nodes=node1.domainname.com myjob.sh

instead of just doing

qsub nodes=node1 myjob.sh

So I went and chopped down the names of all my nodes in the /var/spool/pbs/nodes file to use the short name instead. PBS is still working fine, but my /var/log/messages file keeps filling up with errors saying that the head node can't talk to the pbs_mom service on other nodes. Was I supposed to make this change in any file on the worker nodes? Am I missing something?

perhaps instead of changing the file names of that app to saving you some typing, you could just create an alias for the full command in your shell?

Thanks for the response Kahless... I already have an alias in the hosts file. I thought of that too, but didn't help.
