S.L.LloydATSE e-Science Visit April 2004Slide 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) GridPP £17m "From Web to Grid" GridPP £15m "From Prototype to Production"

S.L.LloydATSE e-Science Visit April 2004Slide 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

S.L.LloydATSE e-Science Visit April 2004Slide 3 The CERN Large Hadron Collider 4 Large Experiments The worlds most powerful particle accelerator

S.L.LloydATSE e-Science Visit April 2004Slide 4 The LHC Experiments > 10 8 electronic channels 8x10 8 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) Searching for the Higgs Particle and exciting new Physics Starting from this event Looking for this signature e.g. ATLAS

S.L.LloydATSE e-Science Visit April 2004Slide 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)

S.L.LloydATSE e-Science Visit April 2004Slide 6 GridPP International Collaboration 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

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