User-Assigned Job Priority
User-assigned job priority provides controls that allow users to order their jobs in a
queue. Job order is the first consideration to determine job eligibility for dispatch.
Jobs are still subject to all scheduling policies regardless of job priority. Jobs with the
same priority are ordered first come first served.
The job owner can change the priority of their own jobs. LSF and queue
administrators can change the priority of all jobs in a queue.
User-assigned job priority is enabled for all queues in your cluster, and can be
configured with automatic job priority escalation to automatically increase the
priority of jobs that have been pending for a specified period of time.
Considerations
The btop and bbot commands move jobs relative to other jobs of the same priority.
These commands do not change job priority.
