PDSF LSF Batch Performance from January 1, 2004 to
less than January 1, 2005
Number of CPU's available during the accounting period: 366
Number of CPU days available on the cluster: 366 (days) * 366 (nodes) = 133956 days
Number of jobs run during that time: 50587
Wall clock time used by the jobs: 265.90 days (0.20% utilization)
CPU time used by the jobs: 40.98 days (15.41% efficiency)

The Efficiency number may be greater than 100% if the processes used threads. SGE aggregated all thread cpu time together, thus efficiency is based on cpu time verses wall clock time.
