LSF Version 7.3 - Platform LSF Configuration Reference

Notes
•
By default, the PRIORITY range defined for queues in cross-queue fairshare cannot be
used with any other queues. For example, you have 4 queues: queue1, queue2, queue3,
queue4. You configure cross-queue fairshare for queue1, queue2, queue3 and assign
priorities of 30, 40, 50 respectively.
•
By default, the priority of queue4 (which is not part of the cross-queue fairshare) cannot
fall between the priority range of the cross-queue fairshare queues (30-50). It can be any
number up to 29 or higher than 50. It does not matter if queue4 is a fairshare queue or
FCFS queue. If DISPATCH_ORDER=QUEUE is set in the master queue, the priority of
queue4 (which is not part of the cross-queue fairshare) can be any number, including a
priority falling between the priority range of the cross-queue fairshare queues (30-50).
•
FAIRSHARE must be defined in the master queue. If it is also defined in the queues listed
in FAIRSHARE_QUEUES, it is ignored.
•
Cross-queue fairshare can be defined more than once within lsb.queues. You can define
several sets of master-slave queues. However, a queue cannot belong to more than one
master-slave set. For example, you can define:
•
In queue normal: FAIRSHARE_QUEUES=short license
•
In queue priority: FAIRSHARE_QUEUES=night owners
Restriction:
You cannot, however, define night, owners, or priority
as slaves in the queue normal; or normal, short and
license as slaves in the priority queue; or short,
license, night, owners as master queues of their own.
•
Cross-queue fairshare cannot be used with host partition fairshare . It is part of queue-
level fairshare.
•
Cross-queue fairshare cannot be used with absolute priority scheduling.
