To configure subordinate queues, click the Subordinates tab. The Subordinates tab is shown in the following figure.
Use the subordinate queue facility to implement high priority and low priority queues as well as standalone queues.
You can specify the following parameters:
Queue. A list of the queues that are subordinated to the configured queue.
Subordinated queues are suspended if the configured queue becomes busy. Subordinated queues are resumed when the configured queue is no longer busy.
Max Slots. For any subordinated queue, you can configure the number of job slots that must be filled in the configured queue to trigger a suspension. If no maximum slot value is specified, all job slots must be filled to trigger suspension of the corresponding queue.
See the queue_conf(5) man page for detailed information about these parameters.
