T2 Sites reports



    • LHEP:
      • Old node replacement 90% complete
      • 80*48core nodes awaiting deployment (50kHS06)
      • Issues with 1 out of 3 ARC CEs (detailed in general T2 report)
    • UBELIX:
      • NTR, smooth operation, aside for one occurrence of ARC DTR stuck as well

    • UNIGE:
      • Nothing new to report
      • CPU efficiency is remarkably lower than normal ATLAS values

  • Accounting ATLAS dashboard vs slurm: within 25% (abnormal, usually within 2%)
  • Accounting CRIC vs slurm: -30% for WallClock, -40% for HS06
  • Accounting CRIC vs ATLAS DDM storage: -N/A

T3 Sites reports




  • Yearly review of the information about sites in GOCDB
  • Transition from X509 to federated identities (AARC profile token)
    • complex scenario, but in a nutshell we can summarise it like follows for now:
      • Services
        • CEs to fully support tokens by the end of the year (Dirac for the job submission)
        • data management services (dCache, STORM, FTS, Rucio, Dirac) might need a few years before droppin X509/VOMS support
      • Migration of the VOs from VOMS to Check-in

        • transition period where both X509 and tokens can be used
        • delays in updating the GRID elements to the latest version compliant with tokens
        • not all if the middleware products can be compliant with tokens at the same time
        • the same VO has to interact with element supporting different authentications

    • Recent statement: expect need for x509 certificates at least until end of 2025

  • New Benchmark to replace HEPSPEC06
    • Nothing new compared to last month
    • Comment from an insider: "HEPSCORE benchmark is still far from becoming a reality"

  • New ARGO UI
