  • Marco: Debugging glideinWMS compatibility issues with HTCondor 9.0.6; attempting to install 9.0.1 for testing but having dependency issues. Brian says that it's a frequent issue when trying to install old versions of HTCondor on EL7. Mat suggests trying the HTCondor Docker images if a 9.0.1 version is available.

Support Update

  • TimT: Justas (Caltech) is requesting additional GPU attributes in the job classad; Tim will link him up with one of the HTCondor developers directly.
  • Carl: There is no easy upgrade path to the Python 3 version of gfal2-util due to RPM dependency issues; filed a ticket with EPEL, will try to contact developers directly if there's no response to the ticket.
  • Marian: Continuing to support LIGO with using IDTOKEN authentication.

OSG DevOps

New: - Transition to IDTOKENs for IGWN, JLab, GLUEX

Ongoing: - Shoveler and Collector is tested, now converting UNL to using the shoveler. - Request to inject entire HTCondor job classad into GRACC records. Will require gratia-probe-condor changes.

Back burner: - (Stalled, but need to get back to it) XRootD accounting information (from Frank): - May need help with automating the process of generating these reports. A month only takes a few minutes. Longer periods take much longer. - Table of working set, read, and re-read for monthly, quarterly, and year. - XRootD TCP plugin is ready for packaging. Derek will follow up with software team on who to hand that off to. -
