ask a job to release its worker job slots, let the current work (frame) finish |
Description
qbpreempt requests the Supervisor to tell a job to release its host if and when it can do so without wasting CPU time. The job will be removed from the host when it finishes the frame or agenda item it's working on, and asks the Supervisor for another agenda item. Instead, the Supervisor will instruct the job to "get off" the worker.
The job instance that was removed from the worker will then go back into a pending state, and await re-dispatch as workers again become available.
This command depends upon the job type and will only work if the job that is running supports a qube agenda-based system.
Usage
qbpreempt [options] jobID… | 0
where JobID is one or more job IDs, and 0 is a wild card token representing all the user's jobs.
