PEND_REASON_UPDATE_INTERVAL
Syntax
PEND_REASON_UPDATE_INTERVAL=
seconds
Description
Time interval that defines how often pending reasons are calculated by the scheduling
daemon
mbschd.
Default
30 seconds
PEND_REASON_MAX_JOBS
Syntax
PEND_REASON_MAX_JOBS=
integer
Description
Number of jobs for each user per queue for which pending reasons are calculated by the
scheduling daemon
mbschd. Pending reasons are calculated at a time period set by
PEND_REASON_UPDATE_INTERVAL.
Default
20 jobs
PG_SUSP_IT
Syntax
PG_SUSP_IT=
seconds
Description
The time interval that a host should be interactively idle (it > 0) before jobs suspended
because of a threshold on the
pg load index can be resumed.
This parameter is used to prevent the case in which a batch job is suspended and
resumed too often as it raises the paging rate while running and lowers it while
suspended. If you are not concerned with the interference with interactive jobs caused
by paging, the value of this parameter may be set to 0.
Default
180 (seconds)
PREEMPTABLE_RESOURCES
Syntax
PREEMPTABLE_RESOURCES=
resource_name ...
Description
LicenseMaximizer only. Enables license preemption when preemptive scheduling is
enabled (has no effect if PREEMPTIVE is not also specified) and specifies the licenses
that will be preemption resources. Specify shared numeric resources, static or
decreasing, that LSF is configured to release (RELEASE=Y in
lsf.shared, which is
the default).
You must also configure LSF preemption actions to make the preempted application
releases its licenses. To kill preempted jobs instead of suspending them, set
TERMINATE_WHEN=PREEMPT in
lsb.queues, or set JOB_CONTROLS in
lsb.queues and specify brequeue as the SUSPEND action.
Default
Undefined (if preemptive scheduling is configured, LSF preempts on job slots only)
PREEMPT_FOR
Syntax
PREEMPT_FOR=
[HOST_JLU | USER_JLP | GROUP_MAX | GROUP_JLP | MINI_JOB
|
LEAST_RUN_TIME]...
