OpenPBS is a GPL'd batch queuing system. In brief, both the [Biowulf] and the [Roadrunner] clusters use OpenPBS to distribute compute-jobs across their several nodes.
Common OpenPBS Commands
- qsub -- submit a compute-job for execution
- qstat -- query status of the queues
- qdel -- remove a (possibly running) compute-job
UnCommon OpenPBS Commands
- offline-node -- a simple shell wrapper to [pbsnodes]
- pbsnodes -- maintain which compute-nodes participate the queuing system
- for i in `qstat | grep <username> | awk -F. '{print $1}'` ; do qdel $i ; done -- delete all submitted jobs run by <username>
- checknode <nodename> -- check node with name <nodename>
- diagnose -n | grep -v nonspeedy -- look at all speedy nodes
- tracejob <jobid> -- look at the history of a particular job with ID <jobid> that was run
- diagnose -p -- show priorities
Other Important Queuing Bits
- qstat -q -- What queues exist? --> qstat -q
- showstart -- When will my job run?
- fairshare -- What is the amount my group's cluster usage?
- showq -- show jobstart order
How to manage job output
- stdout and stderr
