  1. GridPP Building a UK Computing Grid for Particle Physics Professor Steve Lloyd, Queen Mary, University of London Chair of the GridPP Collaboration Board

  2. Outline • Why? – The CERN LHC and the Data Deluge • What? - GridPP and the Grid • What is the Grid? • Applications and Middleware • Tier-1 and Tier-2 Regional Centres • How? - GridPP Management • Summary and Challenges Public Service Summit - 22 September 2004

  3. What is GridPP? 19 UK Universities, CCLRC (RAL & Daresbury) and CERN Funded by the Particle Physics and Astronomy Research Council (PPARC) GridPP1 - 2001-2004 £17m "From Web to Grid" GridPP2 - 2004-2007 £15m "From Prototype to Production" Public Service Summit - 22 September 2004

  4. The CERN LHC The world’s most powerful particle accelerator - 2007 4 Large Experiments Public Service Summit - 22 September 2004

  5. LHC Experiments Searching for theHiggs Particle and exciting new Physics e.g. ATLAS Starting from this event Looking for this ‘signature’ • > 108 electronic channels • 8x108 proton-proton collisions/sec • 2x10-4 Higgs per sec • 10 Petabytes of data a year • (10 Million GBytes = 14 Million CDs) Public Service Summit - 22 September 2004

  6. What is the Grid? Your Program Single PC Grid Your Program PROGRAMS MIDDLEWARE User Interface Machine Word/Excel Games Email/Web Resource Broker OPERATING SYSTEM Information Service CPU Disks, CPU etc Middleware is the Operating System of a distributed computing system CPU Cluster CPU Cluster CPU Cluster Disk Cluster Public Service Summit - 22 September 2004
