Re: [Condor-users] Jobs being preempted with default rank settings

[David Dynerman <dynerman@xxxxxxxxxxx>]

Hey Todd,

Here's an example of a job that's sitting idle:

055.017:  Run analysis summary.  Of 128 machines,
      8 are rejected by your job's requirements
     45 reject your job because of their own requirements
     45 match but are serving users with a better priority in the pool
     30 match but reject the job for unknown reasons
      0 match but will not currently preempt their existing job
      0 are available to run your job
        Last successful match: Fri Jul 18 10:13:10 2008

condor_status -available lists 30 unclaimed idle machines
