  1. GridPP – A UK Computing Grid for Particle Physics 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" www.gridpp.ac.uk ATSE e-Science Visit April 2004

  2. Outline • Why? – The CERN LHC and the Data Deluge • What? - GridPP and the Grid • Applications • Middleware • Tier-1 and Tier2 Regional Centres • Future Challenges • How? - GridPP Management • Summary ATSE e-Science Visit April 2004

  3. The CERN Large Hadron Collider The world’s most powerful particle accelerator - 2007 4 Large Experiments ATSE e-Science Visit April 2004

  4. The LHC Experiments e.g. ATLAS Searching for theHiggs Particle and exciting new Physics Starting from this event Looking for this ‘signature’ • > 108 electronic channels • 8x108 proton-proton interactions/sec • 2x10-4 Higgs per sec • 10 Petabytes of data a year • (10 Million GBytes = 14 Million CDs – twice the height of Everest) ATSE e-Science Visit April 2004

  5. What is GridPP? A team that have built a working prototype Grid • hundreds of computers across 16 UK institutions • Allows scientists to access data and processing power seamlessly, wherever they are • No need for accounts at many different universities • No need for lots of passwords • ‘Middleware’ detects where the computing power and data is available and deals with security Working with other disciplines • e.g. UK e-Science (Grid deployment) medical researchers (Grid security) • BT (Grid Info. Services, networking) ATSE e-Science Visit April 2004

  6. CERN IT – PPARC funded £5.7m for staff and hardware prototype LHC Computing Grid went live in September 2003 in 12 countries UK sites among the first to join Grid Operations Centre based at RAL, UK EU DataGrid – PPARC one of 6 main partners GridPP software central to the project testbed at more than 40 sites across Europe with 1,000+ computer processors around 100,000 jobs successfully submitted via the UK to the prototype EU-wide grid 3 main areas high energy physics biology and medical image processing Earth observation GridPP International Collaboration ATSE e-Science Visit April 2004

  7. What is a Grid? I. Experiment Layer e.g. Portals II. Application Middleware e.g. Metadata "Hour Glass" III. Grid Middleware e.g. Information Services IV. Facilities and Fabrics e.g. Storage Services ATSE e-Science Visit April 2004
