  1. The Grid What is it?What is it for?

  2. CERN

  3. 27Km Around

  4. ALICE CMS 4 Experiments LHCb ATLAS

  5. Answering the BIG question • What actually happened at the big bang? Answering other questions • How does gravity work? • How do particles have mass? • Where is the rest of the universe?

  6. Combined they will create 15PB of Data every year That’s the equivalent of 22 Trillion Sheets of A4 More than any single, current, system can handle

  7. The Problem Solution needs to be: • Able to handle massive amounts of data • Able to process large computing jobs • Relatively inexpensive • Simple to use • Accessible 24/7 • Easily upgraded

  8. Super Computers? So we just build them bigger? But: • Expensive • Inaccessible • Easily outdated

  9. Solution: The Internet? The network which physically connects the worlds computers allowing them to communicate

  10. Tools built upon the Internet • Worldwide Web • File Sharing networks • BOINC e.g. SETI@home The Web specifically designed by scientists at CERN to help with their work

  11. The Next Stage • Build a new tool • The computers in the institutions are already connected • They already share files • How about sharing everything?

  12. The Electricity Grid • Always on • As much or as little as you need on tap • Where/how power is generated is irrelevant to the end user • Just plug in and go

  13. A Computing Grid • Always on • As much or as little as you need on tap • Where/how computing power is generated is irrelevant to the end user • Just plug in and go

  14. Before • Distributed computing has been available to scientists for some time but: • The use of different sites has to be negotiated by each scientist individually. • They need a separate account on each system. • Jobs have to be submitted and results collected back by hand. Current distributed computing means the user has a lot of work to do to get any work done.

  15. After Middleware lets users simply submit jobs to the Grid without having to know where the data is or where the jobs will run. The software can run the job where the data is, or move the data to where there is CPU power available. Using the Grid and middleware, all the user has to do is submit a job and pick up the results.

  16. GridPP is a collaboration of Particle Physicists and Computing Scientists from 20 UK universities and CERN, who are building the UK arm of the Grid for Particle Physics.

GridPP Lancaster University University Of Liverpool University Of Manchester University Of Sheffield Durham University University Of Edinburgh University Of Glasgow Brunel University Imperial College London Queen Mary, University Of London Royal Holloway, University Of London University College London Swansea University University Of Birmingham University Of Bristol University Of Cambridge University Of Oxford Rutherford Appleton Laboratory Warwick University University of Sussex

  18. Numbers • 20 Institutes • 100+ Individuals • 280TB of storage • Equivalent of 6,420 desktop computers Later this year we will have the equivalent of 10,000 desktop PCs on our Grid

  19. Projects We are members of two Grid projects: • LCG • LHC Computing Grid • EGEE • Enabling Grids for E-sciencE

  20. Beyond Particle Physics • WISDOM Challenges: • Avian Flu • 100 years work done in 4 weeks • Malaria • 50% of computing power provided by GridPP • Inferno Grid • Humanities Project in Montclair University New Jersey • Current texts available on the system include Aristotle, Galen, Plato, Marcus Aurelius, and Commentaries
