Suspend a job


Run bstop job_ID.

Your job goes into USUSP state if the job is already started, or into PSUSP state if it is pending.

bstop 3421
Job <3421> is being stopped

The preceding example suspends job 3421.



bstop sends the following signals to the job:

  • SIGTSTP for parallel or interactive jobs—SIGTSTP is caught by the master process and passed to all the slave processes running on other hosts.

  • SIGSTOP for sequential jobs—SIGSTOP cannot be caught by user programs. The SIGSTOP signal can be configured with the LSB_SIGSTOP parameter in lsf.conf.


bstop causes the job to be suspended.
