PDSF LSF Batch Performance from October 1, 2002 to
    less than November 1, 2002


Number of CPU's available during the accounting period:
Number of CPU days available on the cluster: 31 (days) * 0 (nodes) = 0 days

Number of jobs run during that time: 725
Wall clock time used by the jobs: 170.51 days (0.00% utilization)
CPU time used by the jobs: 166.34 days (97.56% 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.
