Discussion

Decided that sending the weekly email on Thursday is fine for the "Ready for Testing" announcements.

OSG Investigations

  • Simple validation of xrootd-monitoring-collector passed.
    • Working now with Bockjoo on production validation. Step 1 is making a public test collector
    • Working with Brian (and Frank?) on GRACC changes.
  • Update of GRACC ES, which may require some development changes. Hopefully updating this week.
  • cvmfs-singularity-sync development for for python3 update.
  • NSF science bucket metadata for GRACC development this week.

Discussion

Derek will try to tackle the FoS -> NSF bucket mapping for the GRACC this week, or contact BrianL for delegation
