Configuring a Chunk Job Dispatch
Administering Platform LSF

If CHUNK_JOB_DURATION is set in lsb.params, the job is chunked only if
it is submitted with a run limit that is less than or equal to the value of
CHUNK_JOB_DURATION (
bsub -W)
Jobs submitted with the corresponding
bsub options are not chunked; they are
dispatched individually:
◆ -I (interactive jobs)
◆ -c (jobs with CPU limit greater than 30)
◆ -W (jobs with run limit greater than 30 minutes)
