Discussion

We would like to get HTCondor 8.8 into mainline but the default auth removes DAEMON_LIST so it could break current installations of HTCondor

OSG Investigations Team

  • cvmfs-authz-helper (cvmfs-x509-helper) - Testing continues
  • HTCondor-CE Gratia probe installed and running at Nebraska slurm. Records look ok. Need to perform a "checklist" of attributes to make sure we are correct.
    • https://opensciencegrid.atlassian.net/browse/SOFTWARE-3748
  • CMS asked for application specific attributes to be added to the XRootD Detailed Monitoring Collector.
  • GRACC accounting taskforce - Tasking!!!

Backburner

  • Working with operations investigating OAuth with co-manage. Waiting on co-manage (Wisconsin?!?!)

Future

Ongoing
