OSG Software Team

  • Release
    • AI (Carl): Cut new Gratia Probe 2.x RPM
    • AI (Mat): XRootD in OSG 3.6 (SOFTWARE-4494)
  • GSI Transition
    • AI (Carl): Review osg-token-renewer doc and merge if satisfied
  • Other
    • AI (BrianL): Add SSH certificate to the Hosted CE
    • AI (BrianL): Add Topology endpoint for querying resources tied to VOs
    • AI (BrianL): Add Singularity backfill container CI tests
    • AI (BrianL): Investigate host cert on the CMS Hosted CE at Frontera to see if UW needs to renew it


  • GlideinWMS 3.9.3rc1 available; will be built into 3.5-contrib; requesting a build for 3.6 as well. GSI not completely removed yet but that's acceptable because it will help with the transition

  • FNAL and CERN expected to announce EL8 plans in October

Support Update

  • Florida (BrianL): uncovered a few bugs with job router transforms in HTCondor-CE 5.1.1. To be fixed in 5.1.2 in an expected upstream release this week.
  • Marian: add Andrew Melo back as an OASIS manager; contact Mat if Topology assistance is needed
  • Mat: Assist Vlad at IceCube with permissions problems at their new Stash Origin; contact Derek for assistance as needed
  • Carl: LIGO fixed their ProbeConfig and some records started showing up. LIGO-WA-CalTech records are sparse; Carl will ask LIGO if this is expected

OSG DevOps

New: - GRACC update completed; backup service verification to come this week. - Request to inject entire HTCondor job classad into GRACC records. Will require gratia-probe-condor changes. - Stashcp changes to support authenticated reading from /ospool namespace.

Ongoing: - Shoveler is working and lightly tested. Collector is 90% done. - Checksums in xrootd-multiuser is 80% done.

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. -
