Support Update

  • Edgar: StashCache at PIC upgraded to the upcoming-fresh version but it's broken for them. Edgar is troubleshooting; will reach out to XRootD developers for assistance. The symptom is an SSL permission denied, but the error only shows up in XRootD 5 and goes away when they downgrade.

GlideinWMS News

  • Marco Mascheroni testing 3.6.4 in the ITB. (This will be in OSG 3.4 and OSG 3.5.)
  • 3.9 now in osg-contrib (this includes Python 3 support).
  • Continuing work on 3.7; integrating some work from the recent tokens hackathon.
