qhold can be used to hold a job (if one of your jobs is blocking another) this is cancelled by qrls.
If modifying the resource allocation, e.g. -lnodes=4:ppn=12 for a 48 core job, make sure to use the old specifier if you want 12-core nodes, otherwise the 16-core ones get allocated, wasting 4 cores each.
-lnodes=4:old:ppn=12
checkjob JOBID
will tell you about why something isn't running.
showstart JOBID
will tell you when job JOBID is expected to start, so you can submit a job shorter than this and it will be backfilled into the reservation.
