LSF Version 7.3 - Platform LSF Configuration Reference

Commands to control
Command Description
bmig
•
Migrates one or more running jobs from one host to another. The jobs must be
checkpointable or rerunnable
•
Checkpoints, kills, and restarts one or more checkpointable jobs—bmig combines
the functionality of the bchkpnt and brestart commands into a single command
•
Migrates the job on demand even if you have configured queue-level or host-level
migration thresholds
•
When absolute job priority scheduling (APS) is configured in the queue, LSF
schedules migrated jobs before pending jobs—for migrated jobs, LSF maintains the
existing job priority
bmod -mig
migration_threshold | -
mign
•
Modifies or cancels the migration threshold specified at job submission for
checkpointable or rerunnable jobs. Enables or disables 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 display configuration
Command
Description
bhosts -l
•
Displays information about hosts configured in lsb.hosts, including the values
defined for migration thresholds in minutes
bqueues -l
•
Displays information about queues configured in lsb.queues, including the values
defined for migration thresholds
Note:
The bqueues command displays the migration threshold
in seconds—the lsb.queues MIG parameter defines the
migration threshold in minutes.
badmin showconf
•
Displays all configured parameters and their values set in lsf.conf or ego.conf
that affect mbatchd and sbatchd.
Use a text editor to view other parameters in the lsf.conf or ego.conf
configuration files.
•
In a MultiCluster environment, badmin showconf only displays the parameters of
daemons on the local cluster.
