LSF Version 7.3 - Platform LSF Configuration Reference

RUNLIMIT is required for queues configured with INTERRUPTIBLE_BACKFILL.
Default
Unlimited
SLOT_POOL
Syntax
SLOT_POOL=pool_name
Description
Name of the pool of job slots the queue belongs to for queue-based fairshare. A queue can only
belong to one pool. All queues in the pool must share the same set of hosts.
Valid value
Specify any ASCII string up to 60 characters long. You can use letters, digits, underscores (_)
or dashes (-). You cannot use blank spaces.
Default
Not defined. No job slots are reserved.
SLOT_RESERVE
Syntax
SLOT_RESERVE=MAX_RESERVE_TIME[integer]
Description
Enables processor reservation for the queue and specifies the reservation time. Specify the
keyword MAX_RESERVE_TIME and, in square brackets, the number of MBD_SLEEP_TIME
cycles over which a job can reserve job slots. MBD_SLEEP_TIME is defined in
lsb.params; the default value is 60 seconds.
If a job has not accumulated enough job slots to start before the reservation expires, it releases
all its reserved job slots so that other jobs can run. Then, the job cannot reserve slots for one
scheduling session, so other jobs have a chance to be dispatched. After one scheduling session,
the job can reserve job slots again for another period specified by SLOT_RESERVE.
SLOT_RESERVE is overridden by the RESOURCE_RESERVE parameter.
If both RESOURCE_RESERVE and SLOT_RESERVE are defined in the same queue, job slot
reservation and memory reservation are enabled and an error is displayed when the cluster is
reconfigured. SLOT_RESERVE is ignored.
Job slot reservation for parallel jobs is enabled by RESOURCE_RESERVE if the LSF scheduler
plugin module names for both resource reservation and parallel batch jobs
(schmod_parallel and schmod_reserve) are configured in the lsb.modules file: The
schmod_parallel name must come before schmod_reserve in lsb.modules.
If BACKFILL is configured in a queue, and a run limit is specified at the job level (bsub
-W), application level (RUNLIMIT in lsb.applications), or queue level (RUNLIMIT in
lsb.queues
