      • Installing WNs at CINECA next week
      • Start working on getting all services tested and online
    • Group Derivation Production
      • SharedWriter is being tested - at least one format has issues with metadata
      • MemoryMonitor issue still unresolved
      • Latest cache 21.2.16.0 built yesterday only for TAU group
      • 3.5PB marked for deletion very soon
      • Discussion of shares - current: GP_PHYS 10% (mostly data), GP_GROUP 3% only MC. Maybe go 50/50
    • MC Production
      • MC16d bulk production as complete as can be at this point (except INFN inputs)
      • Recovering from rucio issues still
      • Fed two more large MC16e simul to P1
      • Remainder of large BPHYS sample to come (several 100M) - could do as ES, clarify with PMG
      • Not much pile up running, some waiting on INFN inputs
      • List of user requests slowly going down
    • Reprocessing
      • First part of data17 reprocessing
        • Handful of jobs (~12) in period D and E needed to be obsoleted and retried (mainly merge steps)
      • [RUNNING] Period B 15+1 runs to fix alignment errors in first reprocessing pass (no fork after first event)
      • [RUNNING] Reprocessing of period F, H, I and K queued/started.
    • CRC/ADCoS Report
      • Running usual 250-300k slots
      • Had low number of jobs due to less MC
      • Issue with unacknowledged transfers in rucio for a period
      • Heavy Ion overlay jobs overloading CERN and Lyon frontiers
      • Discussion about CRC time spent on inefficient sites and investigation
      • Some T0 issues with CERN-PROD - being followed up
      • Still investigating issues with INFN-T1 transfer failures via RAL FTS
      • No CRC shifter for next 3 months - encourage signup
