Dispatch and Run Windows
Both dispatch and run windows are time windows that control when LSF jobs start and
run.
◆ Dispatch windows can be defined in lsb.hosts. Dispatch and run windows can
be defined in
lsb.queues.
◆ Hosts can only have dispatch windows. Queues can have dispatch windows and run
windows.
◆ Both windows affect job starting; only run windows affect the stopping of jobs.
◆ Dispatch windows define when hosts and queues are active and inactive. It does not
control job submission.
Run windows define when jobs can and cannot run. While a run window is closed,
LSF cannot start any of the jobs placed in the queue, or finish any of the jobs already
running.
◆ When a dispatch window closes, running jobs continue and finish, and no new jobs
can be dispatched to the host or from the queue. When a run window closes, LSF
suspends running jobs, but new jobs can still be submitted to the queue.
