Fairshare Scheduling<br />

As queue1 and queue2 finish their jobs, the number of jobs in queue3<br />

expands, and as queue1 and queue2 get more work, <strong>LSF</strong> rebalances the usage:<br />

10 queues sharing<br />

10% each of 50<br />

slots<br />

In this example, queue1 (the curve with the highest peaks) has the longer<br />

running jobs and so has less accumulated slots in use over time. <strong>LSF</strong><br />

accordingly rebalances the load when all queues compete for jobs to maintain<br />

a configured 10% usage share.<br />
