LSF Version 7.3 - Platform LSF Configuration Reference

If checkpoint-related configuration is specified in the queue, application profile, and at job
level:
•
Application-level and job-level parameters are merged. If the same parameter is defined
at both job-level and in the application profile, the job-level value overrides the application
profile value.
•
The merged result of job-level and application profile settings override queue-level
configuration.
To enable checkpointing of MultiCluster jobs, define a checkpoint directory in an application
profile (CHKPNT_DIR, CHKPNT_PERIOD, CHKPNT_INITPERIOD,
CHKPNT_METHOD in lsb.applications) of both submission cluster and execution
cluster. LSF uses the directory specified in the execution cluster.
Checkpointing is not supported if a job runs on a leased host.
Default
Not defined
CHKPNT_INITPERIOD
Syntax
CHKPNT_INITPERIOD=init_chkpnt_period
Description
Specifies the initial checkpoint period in minutes. CHKPNT_DIR must be set in the
application profile for this parameter to take effect. The periodic checkpoint specified by
CHKPNT_PERIOD does not happen until the initial period has elapse.
Specify a positive integer.
Job-level command line values override the application profile configuration.
If administrators specify an initial checkpoint period and do not specify a checkpoint period
(CHKPNT_PERIOD), the job will only checkpoint once.
If the initial checkpoint period if a job is specified, and you run bchkpnt to checkpoint the
job at a time before the initial checkpoint period, the initial checkpoint period is not changed
by bchkpnt. The first automatic checkpoint still happens after the specified number of
minutes.
