Open questions: 

  • JOB ID question from Daniel

    • When I submit a job, I get a job ID back. My plan is to hold onto that job ID permanently for tracking. We have had issues in the past with Torque/Maui because the job IDs got recycled later and our internal bookkeeping got mixed up. So my questions are:

       - Are job IDs guaranteed to be unique in HTCondor?
       - How unique are they—are they _globally_ unique or just unique within a particular namespace (such as our cluster or the submit node)?

    • A Job ID (ClusterID.ProcID)
    • DNS name of the schedd and ctime of the job_queued.log file.
    • It is unique to a schedd.
    • We should talk with Daniel about this.  They should craft their own ID.  It could be seeded with a JobID but should not depend on just it.
  • UpgradingHTCondor without killing jobs?
    • schedd can be upgraded and restarted without loosing state assuming the restart is less than the timeout.
    • currently restarting execute services will kill jobs.  CHTC is working on improving this.
    • negotiator and collector can be restarted without killing jobs.
    • CHTC works hard to ensure 8.8.x is compatible with 8.8.y or 8.9.x is compatible with 8.9.y.
  • Leaving data on execution host between jobs (data reuse)
    • Todd is working on this now.
  • Ask about installation of CASA locally and ancillary data (cfcache)
  • No labels
