Platform LSF Administration Guide Version 6.2

Typical Slot Allocation Scenarios
Administering Platform LSF
302
3 queues in one
pool with 50%,
30%, 20% shares
A pool configures 3 queues:
◆ queue1 50% with short-running jobs
◆ queue2 20% with short-running jobs
◆ queue3 30% with longer running jobs
As
queue1 and queue2 finish their jobs, the number of jobs in queue3 expands, and
as
queue1 and queue2 get more work, LSF rebalances the usage:
10 queues sharing
10% each of 50
slots
In this example, queue1 (the curve with the highest peaks) has the longer running jobs
and so has less accumulated slots in use over time. LSF accordingly rebalances the load
when all queues compete for jobs to maintain a configured 10% usage share.
