If a job is restarted, LSF attempts to restart the job with the -restart option appended to the original fluent command. Fluent uses the checkpointed data and case files to restart the process from that checkpoint point, rather than repeating the entire process.

Each time a job is restarted, it is assigned a new job ID, and a new job subdirectory is created in the checkpoint directory. Files in the checkpoint directory are never deleted by LSF, but you may choose to remove old files once the Fluent job is finished and the job history is no longer required.
