Changing Job Order Within Queues

Chapter 6
Managing Jobs
By default, LSF dispatches jobs in a queue in the order of arrival (that is,
first-come-first-served), subject to availability of suitable server hosts.
Use the btop and bbot commands to change the position of pending jobs, or
of pending job array elements, to affect the order in which jobs are considered
for dispatch. Users can only change the relative position of their own jobs, and
LSF administrators can change the position of any users’ jobs.
Moves jobs relative to your last job in the queue.
If invoked by a regular user, bbot moves the selected job after the last job with
the same priority submitted by the user to the queue.
If invoked by the LSF administrator, bbot moves the selected job after the last
job with the same priority submitted to the queue.
Moves jobs relative to your first job in the queue.
If invoked by a regular user, btop moves the selected job before the first job
with the same priority submitted by the user to the queue.
If invoked by the LSF administrator, btop moves the selected job before the
first job with the same priority submitted to the queue.
Moving a job to the top of the queue
In the following example, job 5311 is moved to the top of the queue. Since job
5308 is already running, job 5311 is placed in the queue after job 5308.
Note that user1’s job is still in the same position on the queue. user2 cannot
use btop to get extra jobs at the top of the queue; when one of his jobs moves
up the queue, the rest of his jobs move down.
