bslots
displays slots available and backfill windows available for backfill jobs
Synopsis
bslots [-l] [-n slots] [-R "res_req"] [-W [hour:]minutes]
bslots [-h | -V]
Description
The available slots displayed by bslots are not currently used for running jobs and
can be used for backfill jobs.
bslots displays 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, displays all available slots, and the available run times (backfill windows)
for those slots. When no slots are available for backfill,
bslots displays
No backfill window exists at this time
bslots calculates the backfill window based on the estimated start time of potential
backfill jobs. Estimated start time is only relatively accurate according to current
running job information. If running jobs finish earlier or later, estimated start time
may be moved to earlier or later time. There may be a small delay of a few minutes
between the job finish time on which the estimate was based and the actual start
time of the allocated job.
If the available backfill window has no run time limit, its length is displayed as
UNLIMITED.
Options
-l Displays backfill windows in a long multi-line format. The -l option displays host
names and the number of slots on each host available for backfill.
-n slots Specifies required slots (processors). Backfill windows whose widths are equal or
larger than specified value are returned.
When no slots are available for backfill,
bslots -n displays
No backfill window meets these requirements at this time
-R "res_req" Selects hosts for calculating the backfill windows according to the specified
resource requirement. By default, selects hosts of any type. The
-R option only
supports the
select resource requirement string. Other resource requirement
sections are not supported.
When no slots are available for backfill,
bslots -R displays
No backfill window meets these requirements at this time
-W [hour:]minutes Specifies expected runtime limit. Backfill windows whose lengths are equal or
larger than specified value are returned.
When no slots are available for backfill,
bslots -W displays
No backfill window meets these requirements at this time
