  • 1. Collaboration, Big Data and the search for the Higgs Boson Intel European Research and Innovation Conference October 23rd 2012 Andrzej Nowak, CERN openlab Andrzej.Nowak@cern.ch
  • 2. The European Particle Physics Laboratory based in Geneva, Switzerland Founded in 1954 by 12 countries for fundamental physics research in a post-war EuropeIn 2012, it is a global effort of 20 member countriesand scientists from 110 nationalities, working on the world’s most ambitious physics experiments ~2’500 personnel, > 15’000 users ~1 bln CHF yearly budget Andrzej Nowak - Collaboration, Big Data and the search for the Higgs Boson 2
  • 3. • How to explain particles have mass?• What is most of the universe made of?• Why is there little anti-matter?• What happened in the Big Bang? Andrzej Nowak - Collaboration, Big Data and the search for the Higgs Boson 3
  • 4. Mont Blanc (4,808m) Geneva (pop. 190’000)Lake Geneva (310m deep)Andrzej Nowak - Collaboration, Big Data and the search for the Higgs Boson
  • 5. The Large Hadron Collider 27 km underground superconducting ring – possibly the largest machine ever built by man 40 million collisions per second 150-200 MW power consumption Andrzej Nowak - Collaboration, Big Data and the search for the Higgs Boson 5
  • 6. Andrzej Nowak - Collaboration, Big Data and the search for the Higgs Boson 6
  • 7. Andrzej Nowak - Collaboration, Big Data and the search for the Higgs 7 Boson

  • 11. Collaboration on big data and computing The Worldwide LHC Computing GridTier-0 (CERN): data nearly 160 sitesrecording,reconstruction anddistribution ~250’000 coresTier-1: permanentstorage, re-processing, 173 PB of storageanalysisTier-2: Simulation, > 2 million jobs/dayend-user analysis Andrzej Nowak - Collaboration, Big Data and the search for the Higgs Boson 11
  • 12. Cutting edge science• Accelerating Science and Innovation Andrzej Nowak - Collaboration, Big Data and the search for the Higgs Boson 12
  • 13. It would have been impossible to release physics results so quickly withoutthe outstanding performance of the Grid (including the CERN Tier-0) Number of concurrent ATLAS jobs Jan-July 2012 Includes MC production, user and group analysis at CERN, 10 Tier1-s, ~ 70 Tier-2 federations 100 k  > 80 sites > 1500 distinct ATLAS users do analysis on the GRID Available resources fully used/stressed (beyond pledges in some cases) Massive production of 8 TeV Monte Carlo samples Very effective and flexible Computing Model and Operation team  accommodate high trigger rates and pile-up, intense MC simulation, analysis demands from worldwide users (through e.g. dynamic data placement)
