PDSF SGE Batch Performance from March 1, 2006 to
    less than April 1, 2006


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: 5878
Wall clock time used by the jobs: 1041.50 days (0.00% utilization)
CPU time used by the jobs: 952.68 days (91.47% 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.
