Running Parallel Jobs
Displaying available slots for backfill jobs
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.
