Support Update

  • BNL (Edgar): Working on LIGO data frame data working, which is difficult because they get CVMFS config from EGI but cvmfs-x509-helper from OSG.
  • CMS (Marco): helped troubleshoot an issue due to CA expiration over the weekend because of stale CAs in a CMS docker container
  • FNAL (Derek): Worked to get accounting up and running on new cluster using HTCondor-CE probe with SLURM.
  • OSGConnect (Derek): SciTokens CredMon fixes. Causing user submission issues, to top priority.
  • OU (Derek): Helped Horst get a CE up and running on an old cluster. Though, Horst did most of the work.
  • Syracuse (Edgar, Derek): submit host reporting records as pilots
  • UFL (Marco): Troubleshooting issues finding local Singularity with SAM tests
  • Utah (BrianL): Pilots fail to report back to the gWMS collector due to a bad X509_USER_CERT set by Bosco. This is due to a bad Bosco tarball from the CHTC at least 2 weeks ago so any Hosted CEs instantiated during this time may experience these same failures.
