OSG Software Team


  • Doc focus will concentrate on 3.6 documentation; those who can make it should use the whole day
  • GlideinWMS 3.9.1 will be released later today

Support Update

  • Carl:

    • Support ticket for batch vs payload core hour discrepancy (needs further investigation and will be tracked in JIRA instead)
    • Helping Daniel Caunt at Harvard with Topology registration
    • Working with Lincoln B to help UIUC work around CE problems caused by deletion of state at boot time
  • Derek:

    • Working with Purdue to try and resolve missing Gratia data caused by their SLURM database going down and the CE not creating history entries on job removal; BrianL says the latter may be by design
      • These kinds of issues should stop happening once we move to the HTCondor-CE probe instead of the batch system probes
