VO = Value Odded

  • Most VOs represented via their site(s)

    • Cf. feedback presentation

    • ATLAS represented slightly more directly

      • More demanding on T2s  (space tokens and suchlike)

  • Is anyone missing?

    • LCG experiments challenging

    • Other GridPP experiments are also important!


Information publishing
Information Publishing

  • … since you asked

  • Sagarmatha!

  • Publishing according to InstalledCapacity

    • More or less

    • Some rules counterintuitive

    • Some oddities in the implementations

      • Improving – slowly


Future
Future

  • Support diverse VOs

  • Integrate with NGI?

    • doing storage (very) differently
