  1. Introduction John Gordon, STFC GDB meeting @CERN September 8th 2010

  2. Since the Previous Meeting • Data Management and Storage Jamboree,Amsterdam, 16-18 June • EGEE III Final Review Amsterdam 23-24June • LHC OPN, Barcelona, 28-29 June • WLCG Workshop, London, 7-9 July

  3. GDB meetings in 2010 • Second Wednesday of each month • Pre-GDB rooms booked, October • January 13 • February 10 • March 24 • May 12 • June 9 • July 14 • August 11 • September 8 • October 13 • November 10 • December 8

  4. GDB meetings in 2011 • Propose second Wednesday of each month • Rooms booked • Do these dates clash with anything? • Offer from Lyon to visit in March • January 12 • February 9 • March 9 • April13 • May 11 • June 8 • July 13 • August 10 • September 14 • October 12 • November 9 • December 14

  5. Pre-GDB meetings • None currently planned • Could use October for DAaM demonstrators

  6. Forthcoming Events • EGI Technical Forum, Amsterdam,13-17 September • LHCOPN, CERN, 7-8 October • CHEP 10, Taipei, 17-22 October • HEPiX Fall Meeting, Cornell, 1-5 November

  7. GDB Issues • MU Pilot Jobs, SCAS, gLExec • CREAM • SL5 • Enough resources for experiments • Latest software releases SL5 only • Virtualisation • Installed capacity

  8. Main Topics Today • Accounting • Software Distribution • Middleware • Network Monitoring • Operational Feedback from the experiments

  9. Milestones • Pilot jobs, glexec, SCAS, etc (1st July) • Maarten’s summary on agenda • http://litmaath.home.cern.ch/litmaath/GDB/ • CREAM deployment: • >100 sites have a CREAM CE; • still missing job submission from condor-g (needed by ATLAS) • Stability and reliability of CREAM still not good enough to replace LCG-CE, many open tickets Ian.Bird@cern.ch

  10. Milestones – 2 • From DM and virtualisation activities: • Create a small architectural team • Address several strategic questions: (Nov) • Xrootd as a strategy for data access by all experiments? • Need for ability to reserve whole WN (to better use cores) – is this a clear requirement for all experiments? • CERNVM and/or CVMFS as a strategy for all experiments? • Proposal for better managing Information System and data (end Sep) Ian.Bird@cern.ch

  11. Installed capacity • Action has been pending for a long time: • Information requested by RRB/RSG • Significant effort was put into defining and agreeing how to publish and collect the data – via the information system. • Document has been available for some time • Tool (gstat2) now has the ability to present this information  • Significant effort still required to validate this data before it is publishable • Propose to task Tier 1s with validation for Tier 2s, but Tier 1 data is not good yet! • Sites need to publish good data urgently • http://gstat-wlcg.cern.ch/apps/capacities/federations/ Ian.Bird@cern.ch

  12. Published capacities ... Ian.Bird@cern.ch

  14. Milestones – 2 • Storage accounting reports: • For Tier 1 sites, proto-report for beginning Sep • For Tier 2 sites, for end Oct • Before these are regularly published significant effort has to be devoted to checking the published data (see slide on installed capacity) – lots missing! Ian.Bird@cern.ch

  15. Availability Monitoring • Changes discussed in June took place eventually • SAM tests are now evaluated by Nagios. • Previous interface still publishes results in old form with new names. This eased the transition • For how long?

  16. CIC Operations Portal • Asked for additional requirements for more information or how it could be stored/presented better. • Will be discussed at EGI-TF next week.
