      Analysis Systems

      Carry over from 2 weeks ago:

      • Uproot, coffea, ATLAS PHYSLITE
        • Full reading of PHYSLITE latest schema with uproot/coffea 2024 still blocked by https://gitlab.cern.ch/atlas-asg/columnar-analysis-benchmarks/-/issues/1
      • ATLAS OpenData
        • Draft of open data files available now (in final prep)
        • $ rucio list-datasets-rse CERN-PROD_OPENDATA > CERN_PROD_OPENDATA.txt
        • Currently not enough space for the ~60 TB at MWT2_UC_SCRATCHDISK
          while IFS= read -r did; do rucio add-rule "${did}" 1 MWT2_UC_SCRATCHDISK; done < CERN_PROD_OPENDATA.txt
        • Would be useful to have ATLAS open data at AFs for demos and testing of workflows
          • N.B.: Obviously more useful to use more recent ATLAS data, but open data is still useful especially for collaborating on problems with Analysis Systems teams and Scikit-HEP developers

      Software

      Reminder: OSG 3.6 is in critical bug/security fix only mode

      Release

      • HTCondor 23.6.0 (this week)
      • XRootD 5.6.9 + IO time gstream monitoring patch (soon, https://opensciencegrid.atlassian.net/issues/SOFTWARE-5850)

       

      KAPEL + Gratia integration: we've taken a first stab at the Gratia specific container and are testing it against the GRACC ITB

      Security

      WLCG SOC Hackathon outcomes:

      • Further improvement/refinement to the docker-compose configuration for MISP
        • https://github.com/JiscCTI/misp-docker
        • In-progress updates to add support for OIDC nearly complete
        • Goal is to have a straightforward deployment model for WLCG sites
      • Discussion about long-term support for pDNSSOC
        • Currently not production ready (no RPMs etc)
        • Some question as to who will provide support/development
        • Plan is to deploy it at some small subset of WLCG sites along with MISP to see if this is viable/useful prior to solving those problems
      • FNAL hosting a MISP instance?
        • Some discussion with FNAL about hosting a MISP instance that could sync from the WLCG instances (CERN, etc)
        • Could be used to provide threat intel to US WLCG sites
        • Some logistical hurdles remain to be solved, no definite timeline as of yet
    • 13:20 14:00
      Topical Reports: Topical Reports or Technical Discussion

        Discussion on various topics 40m

        Discussion on WLCG/HSF meeting (which is focused on strategy for the future), our plans for DC24 analysis, status of EL9 migrations and evolution of our computing and storage
