  1. GridPP Collaboration Board Friday 3 March 2006

  2. Agenda • Minutes of Previous Meeting • Actions arising • Project Leader and Project Manager reports - Tony Doyle • 2005 Tier-1/2 Outturn - Steve Lloyd • Beyond GridPP2 • Background, LHC Exploitation Planning Review, PPARC Call - Tony Doyle • Bid Strategy, Scope etc – Discussion • Future Project Leader etc – Discussion • AOB • Next meeting GridPP CB Meeting 3 Mar 2006

  3. 2005 Outturn Definitions: • "Promised" is the total that was planned at the Tier-1/A (in the March 2005 planning) and Tier-2s (in the October 2004 Tier-2 MoU) for CPU and storage. These figures appear as pledges in the LCG global planning. • "Delivered" is the total that was physically installed for use by GridPP. Note that this includes LCG and SAMGrid at Tier-2 and LCG and BaBar at Tier-1/A. • "Available" is available for LCG Grid use, i.e. declared via the LCG/EGEE mechanisms and monitored via the Site Functional Tests, with storage via an SRM interface. • "Used" is as accounted for by the Grid Operations Centre for CPU and the GridPP SRM Storage accounting. Note that the Tier-1 storage also includes tape available via an SRM. GridPP CB Meeting 3 Mar 2006

  4. Resources Delivered Now 530 & 400 CPUs GridPP CB Meeting 3 Mar 2006

  5. LCG CPU Usage GridPP CB Meeting 3 Mar 2006

  6. CPU by Experiment Other = mostly H1 and Zeus + some Biomed GridPP CB Meeting 3 Mar 2006

  7. LCG Disk Usage GridPP CB Meeting 3 Mar 2006

  8. Conclusions • MoU Promises 53% CPU 28% Disk delivered - OK • LCG CPU Usage peaked at 30% Tier-2, 68% Tier-1 • Largest users ATLAS and LHCb • Disk resources grew rapidly – usage at Tier-2 grew slowly • Challenge is for experiments to make more use of Tier-2 disk to take pressure off Tier-1 GridPP CB Meeting 3 Mar 2006

  9. Future Management • Project Leader appointed by CB search Committee • Others by Project Leader? • 2.5  1.5 over time? • What about CB itself? • What about Dissemination? GridPP CB Meeting 3 Mar 2006
