Switching Jobs from One Queue to Another Switching Jobs from One Queue to Another Switching a single job Switching all jobs You can use the command bswitch to change jobs from one queue to another. This is useful if you submit a job to the wrong queue, or if the job is suspended because of queue thresholds or run windows and you would like to resume the job. Run bswitch to move pending and running jobs from queue to queue. In the following example, job 5309 is switched to the priority queue: % bswitch priority 5309 Job is switched to queue % bjobs -u all JOBID USER STAT QUEUE FROM_HOST EXEC_HOST JOB_NAME SUBMIT_TIME 5308 user2 RUN normal hostA hostD /job500 Oct 23 10:16 5309 user2 RUN priority hostA hostB /job200 Oct 23 11:04 5311 user2 PEND night hostA /job700 Oct 23 18:17 5310 user1 PEND night hostB /myjob Oct 23 13:45 Run bswitch -q from_queue to_queue 0 to switch all the jobs in a queue to another queue. The example below selects jobs from the night queue and switches them to the idle queue. The -q option is used to operate on all jobs in a queue. The job ID number 0 specifies that all jobs from the night queue should be switched to the idle queue: % bswitch -q night idle 0 Job is switched to queue Job is switched to queue 118 Administering Platform LSF
Forcing Job Execution Chapter 6 Managing Jobs A pending job can be forced to run with the brun command. This operation can only be performed by an LSF administrator. You can force a job to run on a particular host, to run until completion, and other restrictions. For more information, see the brun command. When a job is forced to run, any other constraints associated with the job such as resource requirements or dependency conditions are ignored. In this situation you may see some job slot limits, such as the maximum number of jobs that can run on a host, being violated. A job that is forced to run cannot be preempted. Forcing a pending job to run Run brun -m hostname job_ID to force a pending job to run. You must specify the host on which the job will run. For example, the following command will force the sequential job 104 to run on hostA: % brun -m hostA 104 Administering Platform LSF 119
