◆ Optional. Set PREEMPT_JOBTYPE to enable preemption of exclusive
and backfill jobs. Specify one or both of the keywords EXCLUSIVE and
BACKFILL. By default, exclusive and backfill jobs are only preempted
if the exclusive low priority job is running on a host that is different
than the one used by the preemptive high priority job.

❖ Use resource reservation to reserve the preemption resource (this might be
configured to occur automatically). For dynamic resources, you must
specify a duration as well as a quantity.
❖ Distribute jobs that use the preemption resource in way that allows
preemption to occur between queues (this should happen as a result of the
cluster design).
