The bslots command displays slots reserved for parallel jobs and advance reservations. The available slots are not currently used for running jobs, and can be used for backfill jobs. The available slots displayed by bslots are only a snapshot of the slots currently not in use by parallel jobs or advance reservations. They are not guaranteed to be available at job submission.
By default, bslots displays all available slots, and the available run time for those slots. When no reserved slots are available for backfill, bslots displays "No reserved slots available."
The backfill window calculation is based on the snapshot information (current running jobs, slot reservations, advance reservations) obtained from mbatchd.The backfill window displayed can serve as reference for submitting backfillable jobs. However, if you have specified extra resource requirements or special submission options, it does not insure that submitted jobs are scheduled and dispatched successfully.
bslots -R only supports the select resource requirement string. Other resource requirement selections are not supported.
If the available backfill window has no run time limit, its length is displayed as UNLIMITED.
