Batch processing on Beach is managed by the Torque in conjunction with the Maui scheduler. Torque batch requests (jobs) are shell scripts that contain the same set of commands that you enter interactively.

For example submission scripts, see the Help section under the Supercomputing section. - How do I submit, check the status, and/or delete a batch job?
Use qsub to submit, qstat to check the status of your job, and qdel to delete a batch request. For more information, see the online man pages. - My job is writing output to TMPDIR, how can I look at it as it's being created?
