PREEMPTION
Syntax
PREEMPTION=PREEMPTIVE[[low_queue_name[+pref_level]...]]
PREEMPTION=PREEMPTABLE[[hi_queue_name...]] PREEMPTION=PREEMPTIVE
[[low_queue_name[+pref_level]...]] PREEMPTABLE[[hi_queue_name...]]
Description
PREEMPTIVE
Enables preemptive scheduling and defines this queue as preemptive. Jobs in this queue
preempt jobs from the specified lower-priority queues or from all lower-priority
queues if the parameter is specified with no queue names. PREEMPTIVE can be
combined with PREEMPTABLE to specify that jobs in this queue can preempt jobs in
lower-priority queues, and can be preempted by jobs in higher-priority queues.
PREEMPTABLE
Enables preemptive scheduling and defines this queue as preemptable. Jobs in this
queue can be preempted by jobs from specified higher-priority queues, or from all
higher-priority queues, even if the higher-priority queues are not preemptive.
PREEMPTIVE can be combined with PREEMPTIVE to specify that jobs in this queue
can be preempted by jobs in higher-priority queues, and can preempt jobs in lower-
priority queues.
low_queue_name
Specifies the names of lower-priority queues that can be preempted.
To specify multiple queues, separate the queue names with a space, and enclose the
list in a single set of square brackets.
+pref_level
Specifies to preempt this queue before preempting other queues. When multiple
queues are indicated with a preference level, an order of preference is indicated: queues
lsb.queues
