This article describes how to use some useful MOAB commands and how to submit different types of jobs to the MOAB scheduler at the FSU HPC.

MOAB Command Reference

The following is a brief list of the frequently used MOAB commands. For a full reference see the MOAB user guide.

• showq -- list the jobs in the current queue
• msub -q<queuename> <script> -- submit a job to the moab batch queue. If no queuename is specificed then the default queue is used. The job submission script is required. Use msub --help to see the full list of options. msub returns the jobid.
• checkjob [-v] jobid -- This command allows users to check their job in the event of problems with the job. This command will show you the reason why your job didn't start if it has been deferred or blocked.
• showstats -- shows the job submission history statistics.
• canceljob -- cancels a job, takes as an argument the jobID. As a last resort, you can also use mjobctrl -C jobID if canceljob gives an error.
• showstart -- gives an estimate of when your job will start to run. Since many people don't indicate the predicated run time of their jobs, this estimate can be completely wrong.
