CMS T3_CH_PSI User Meeting

Planned Program

  • What resources do we have in Switzerland in terms of CPU and storage?
  • (my take on ) what tasks to ideally do on
    • the Grid
    • T2_CH_CSCS
    • T3_PSI_CH
  • CMS data management and how it relates to end users
    • How to register your output files in the central DBs (local publishing)
    • CMS name space
      • (How to discover the exact filename of a dataset file at another site)
    • How to transfer data between centers, expected transfer times, possible optimizations
      • Problem: Copying of user generated data between sites (cannot yet be done with phedex - file sizes! CMS may provide merge jobs at some point)
    • Short discussion on how we should organize the management of our space (getting rid of old sets in a convenient way, without undue wasting of everybody's time)
    • Short guidelines on how to access data
  • Developing the T3 (next upgrades)
    • discussion on what use cases users would like to have the systems optimized for, e.g.
      • interactive vs. batch use
      • should we introduce one more queue with short turnaround times?
      • requirements for graphical interactive work? NX-service?
  • Can we improve the communications and information exchange between users and admins? We want to have a lean and efficient system with as few points of entry as possible, and the minimum of policies.
    • Communication tools
      • CERN wiki
      • CSCS T3 and T2 wiki
      • email lists
      • chat?
    • where to report problems, trouble tickets.
  • Very short explanation on how the CMS sites are organized centrally, how the information flows between sites (FacOps project)
