General information about running jobs and logging in can be found in the getting started page

Reminder this is information about the v4 cluster, not the waller cluster; the commands, syntax for batch jobs would be similar. (use qsub, not nsub)

showq displays jobs running

Once you have a job batch file created, you use 'qsub jobname' (not nsub as written in the v4 documentation).

Use: checkjob/canceljob to check on or cancel your job.

Maui 3.2.6p19/Torque 2.3.0; no project ID required.
