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.
Configuring dispatch windows
Dispatch windows can be defined for both queues and hosts. The default is no
restriction, or always open.
Configuring host
dispatch windows
To configure dispatch windows for a host, set DISPATCH_WINDOW in lsb.hosts
and specify one or more time windows. If no host dispatch window is configured, the
window is always open.
Configuring
queue dispatch
windows
To configure dispatch windows for queues, set DISPATCH_WINDOW in
lsb.queues and specify one or more time windows. If no queue dispatch window is
configured, the window is always open.
