Proposal coming this week for making doc review part of the release process

OSG Investigations Team

  • Adding GPU support and transfer logs to GRACC.
  • GRACC nodes getting updated; frontend node getting moved. This should require zero downtime.

  • GRACC caught up from the backlog.

  • Perfsonar data now flowing smoothly through the message broker.
  • NERSC using CMS XRootD Cache.
  • Look for changes in the gratia probe for GPU detection.
