LSF Version 7.3 - Administering Platform LSF
Dispatch Windows
446 Administering Platform LSF
Jobs can be submitted to a queue at any time; if the run window is closed, the jobs
remain pending until it opens again. If the run window is open, jobs are placed and
dispatched as usual. When an open run window closes, running jobs are
suspended, and pending jobs remain pending. The suspended jobs are resumed
when the window opens again.
Configure run windows
1 To configure a run window, set RUN_WINDOW in lsb.queues.
For example, to specify that the run window will be open from 4:30 a.m. to
noon, type:
RUN_WINDOW = 4:30-12:00
You can specify multiple time windows.
For more information about the syntax of time windows, see Specifying Time
Windows on page 269.

Dispatch Windows
Queues can be configured with a dispatch window, which specifies one or more
time periods during which jobs are accepted. Hosts can be configured with a
dispatch window, which specifies one or more time periods during which jobs are
allowed to start.
Once a dispatch window is configured, LSF cannot dispatch jobs outside of the
window. By default, no dispatch windows are configured (the windows are always
open).
Dispatch windows have no effect on jobs that have already been dispatched to the
execution host; jobs are allowed to run outside the dispatch windows, as long as the
queue run window is open.
Queue-level
Each queue can have a dispatch window. A queue can only dispatch jobs when the
window is open.
You can submit jobs to a queue at any time; if the queue dispatch window is closed,
the jobs remain pending in the queue until the dispatch window opens again.
Host-level
Each host can have dispatch windows. A host is not eligible to accept jobs when its
dispatch windows are closed.
