  18. Tracker Trajectographe à silicium Des capteurs en silicium très finement segmentés (rubans et pixels) permettent de suivre la trajectoire des particules et de mesurer leur impulsion Comparable à un appareil photo à 70 millions de pixels prenant 40 millions de clichés par seconde! But: mesurer les trajectoires & l’ impulsion des particules chargées

  19. EM calorimeter 80 000 xtals, lead tungsten oxide, 80% metal: transparent

  20. Trigger and Dataflow Time 40 MHz 16 Million channels 3 Gigacell buffers Charge s Level 1 Pattern 100 kHz Read Out Buffers 200 Gigabytes ms Level 2 1000 Gigabit/s 1 kHz sec 100 Gigabit/s Level 3 100 Hz Permanent Storage 1 Petabyte/y Global collaboration Hans Hoffmann, CERN honorary

  21. Software structure/layers Applications are built on top of frameworks and implementing the required algorithms Applications Event DetDesc. Calib. expt. specific Every experiment has a framework for basic services and various specialized frameworks: event model, detector description, visualization, persistency, interactivity, simulation, calibration, etc. Experiment Framework Simulation DataMngmt. Distrib. Analysis Specialized domains that are common among the experiments ( some in grid middleware) Core Libraries common for expts. Core libraries and services that are widely used and provide basic functionality non-HEP specific software packages Many non-HEP libraries widely used GRID Middleware grids/networks “Software and Grids” OS & Net services Grid 2008; H F Hoffmann, CERN

  22. What to do with the data? @ @CERN in the Grid event filter (selection & reconstruction) Event Summary Data (ESD) processed data detector batch physics analysis raw data Analysis Object Data (AOD) (extracted by physics topic) event reconstruction event generation, simulation individual physics analysis Detector calibration alignment Global collaboration Hans Hoffmann, CERN honorary 22

  23. Balloon (30 Km) CD stack with 1 year LHC data! (~ 20 Km) Concorde (15 Km) Mt. Blanc (4.8 Km) July 2008 “Digital camera”, 150 M pixels, observing: 109 frames/s, recording selected frames: 200/s, ~1 GB/s recorded volume Global collaboration Hans Hoffmann, CERN honorary

  24. Computing GRID the size of the planet!

  25. International cooperation: Russian workers converting shells to CMS detector parts Global collaboration Hans Hoffmann, CERN honorary

  26. Contribution from Pakistan Structure CMS est constitué de plus de 10 000 tonnes d’acier – en comparaison la Tour Eiffel ne pèse “que” 7 000 tonnes! Ce “socle” a été réalisé au Pakistan et est arrivé au CERN par bateau, train et camion!

  27. CMS Global collaboration Hans Hoffmann, CERN honorary

  28. ALICE: an ultra-sensitive eye on the Universe: Quark-gluon plasma?

  29. 31 countries, 109 institutes, 1000 scientific/technical participants

  30. LHCb: an asymmetrical perspective

  31. What is the Grid? The World Wide Web provides seamless access to information that is stored in many millions of different geographical locations In contrast, the Grid is an emerging infrastructure that provides seamless access to computing power, software and data; distributed over the globe enabling CERN users to work from home as if at CERN CERN in everyday life H F Hoffmann CERN honorary

  32. Marek Domaracky CERN in everyday life H F Hoffmann CERN honorary

  33. Provide equal access to the data, software, compute power. . to all participating scientists “e-Science is about more than networks, Grids, High Performance Computing...; e-science is about global collaboration in key areas of science and the next generation of infrastructure that will enable it.”John Taylor, Director Research Councils, UK, 2000 CERN in everyday life H F Hoffmann CERN honorary

  34. e-science infrastructure ingredients people & VOs skills & training computers (HPC; HTC); computer aided services e-libraries archive/curation centres Multidisciplinary Collaborations: Common objectives Open sharing Critical mass Trust and respect >Best efforts Quality Assurance Service-oriented interoperable open software large data repositories; data services communication means facilities, instruments, services networks, services, dark λ CERN in everyday life H F Hoffmann CERN honorary
