PDSF SGE Batch Performance from January 1, 2008 to
    less than February 1, 2008


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: 3291
Wall clock time used by the jobs: 213.17 days (0.00% utilization)
CPU time used by the jobs: 106.92 days (50.16% 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.
