bchkpnt [ bchkpnt_options ] [-k] [ job_ID ]
◆ -k
Specifies checkpoint and exit. The job will be killed immediately after being
checkpointed. When the job is restarted, it continues from the last checkpoint.
◆ job_ID

is migrated, the job is restarted and assigned a new job ID.
brestart [ brestart options ] checkpoint_directory [ job_ID ]
◆ checkpoint_directory
Specifies the checkpoint directory, where the job subdirectory is located.
◆ job_ID
Job ID of the FLUENT job, specifies which job to restart. At this point, the
restarted job is assigned a new job ID, and the new job ID is used for checkpointing.
The job ID changes each time the job is restarted.
bmig [ bsub_options ] [ job_ID ]
◆ job_ID
Job ID of the FLUENT job, specifies which job to restart. At this point, the
