Working with Queues
Adding and Removing Queues
Adding a queue
1 Log in as the LSF administrator on any host in the cluster.
2 Edit lsb.queues to add the new queue definition.
You can copy another queue definition from this file as a starting point;
remember to change the QUEUE_NAME of the copied queue.
Removing a queue
3 Save the changes to lsb.queues.
4 Run badmin reconfig to reconfigure mbatchd.
Adding a queue does not affect pending or running jobs.
IMPORTANT
Before removing a queue, make sure there are no jobs in that queue.
If there are jobs in the queue, move pending and running jobs to another
queue, then remove the queue. If you remove a queue that has jobs in it, the
jobs are temporarily moved to a queue named lost_and_found. Jobs in the
lost_and_found queue remain pending until the user or the LSF
administrator uses the bswitch command to switch the jobs into regular
queues. Jobs in other queues are not affected.
Steps 1 Log in as the LSF administrator on any host in the cluster.
2 Close the queue to prevent any new jobs from being submitted. For
example:
% badmin qclose night
Queue is closed
3 Move all pending and running jobs into another queue. Below, the
bswitch -q night argument chooses jobs from the night queue, and
the job ID number 0 specifies that all jobs should be switched:
% bjobs -u all -q night
JOBID USER STAT QUEUE FROM_HOST EXEC_HOST JOB_NAME
SUBMIT_TIME
5308 user5 RUN night hostA hostD job5 N
ov 21 18:16
5310 user5 PEND night hostA hostC job10 N
ov 21 18:17
% bswitch -q night idle 0
Job is switched to queue
Job is switched to queue
4 Edit lsb.queues and remove or comment out the definition for the queue
being removed.
5 Save the changes to lsb.queues.
6 Run badmin reconfig to reconfigure mbatchd.
