LSF Version 7.3 - Platform LSF Configuration Reference

Default
Not defined
BACKFILL
Syntax
BACKFILL=Y | N
Description
If Y, enables backfill scheduling for the queue.
A possible conflict exists if BACKFILL and PREEMPTION are specified together. A backfill
queue cannot be preemptable. Therefore, if BACKFILL is enabled, do not also specify
PREEMPTION=PREEMPTABLE.
BACKFILL is required for interruptible backfill queues
(INTERRUPTIBLE_BACKFILL=seconds).
Default
Not defined. No backfilling.
CHKPNT
Syntax
CHKPNT=chkpnt_dir [chkpnt_period]
Description
Enables automatic checkpointing for the queue. All jobs submitted to the queue are
checkpointable.
The checkpoint directory is the directory where the checkpoint files are created. Specify an
absolute path or a path relative to CWD, do not use environment variables.
Specify the optional checkpoint period in minutes.
Only running members of a chunk job can be checkpointed.
If checkpoint-related configuration is specified in both the queue and an application profile,
the application profile setting overrides queue level configuration.
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 both the send-
jobs and receive-jobs queues (CHKPNT in lsb.queues), or in an application profile
(CHKPNT_DIR, CHKPNT_PERIOD, CHKPNT_INITPERIOD, CHKPNT_METHOD in
lsb.queues
