LSF Version 7.3 - Platform LSF Configuration Reference

Configuration to modify job migration
You can configure LSF to requeue a migrating job rather than restart or rerun the job.
Configuration file Parameter and syntax Behavior
lsf.conf
LSB_MIG2PEND=1
•
LSF requeues a migrating job rather than restarting
or rerunning the job
•
LSF requeues the job as pending in order of the
original submission time and priority
•
In a MultiCluster environment, LSF ignores this
parameter
LSB_REQUEUE_TO_BOTTO
M=1
•
When LSB_MIG2PEND=1, LSF requeues a
migrating job to the bottom of the queue, regardless
of the original submission time and priority
•
If the queue defines APS scheduling, migrated jobs
keep their APS information and compete with other
pending jobs based on the APS value
Job migration commands
Commands for submission
Job migration applies to checkpointable or rerunnable jobs submitted with a migration
threshold, or that have already started and are either running or suspended.
Command
Description
bsub -mig migration_threshold
•
Submits the job with the specified migration threshold for
checkpointable or rerunnable jobs. Enables automatic job migration
and specifies the migration threshold, in minutes. A value of 0 (zero)
specifies that a suspended job should be migrated immediately.
•
Command-level job migration threshold overrides application profile
and queue-level settings.
•
Where a host migration threshold is also specified, and is lower than
the job value, the host value is used.
Commands to monitor
Command
Description
bhist -l
•
Displays the actions that LSF took on a completed job, including migration to another
host
bjobs -l
•
Displays information about pending, running, and suspended jobs
