  1. Regional Computing Centre for Particle Physics Institute of Physics AS CR (FZU) TIER2 of LCG (LHC Computing Grid) M. Lokajicek

  2. Outline • Mission of the centre • General infrastructure (electricity, cooling, network) • Capacities and services • People and financing • Conclusion

  3. Mission of the centre • Who we are? • Regional Computing Centre for Particle PhysicsInstitute of Physics of the Academy of Sciences of the Czech Republic, Prague • Basic research in particle physics, solid state physics and optics • What are we doing? • Computing support for big international Particle Physics, Nuclear Physics and Astro-particle Physics experiments using grid environment • D0, ATLAS, ALICE, STAR, AUGER, Belle (CESNET) • WLCG TIER2 centre • Solid State Physics computing • From the computing point of view: High Throughput Computing (HPC), large data samples processing, chaotic data analysis (by physicists), parallel computing • Our users? • Collaborating scientists from institutes of the Academy of Sciences of the Czech Republic, Charles University and Czech Technical University and others • Big experiments (grid environment), individual members of the international experiments, local physicists • CESNET (Czech Research Network Provider) • NGI (National Grid Initiative) of EGI (European Grid Initiative) • Delivers special point-to-point computer lines

  4. Computing Centre Infrastructure • Network connections • 1 Gb/s to European GEANT2 • 10 Gb/s to CESNET • CESNET – optical lines E2E • FNAL, TAIPEI, GRIDKA FZK Karlsruhe, BNL • FZÚ, UK, ČVUT, ÚJF Řež • Total electric power • For computers 200 kVAUPS enginegenerator 380 kVA • Air cooling 2x55 kW • Water cooling in 20092 units STULZ, 2x88 kVATotal 290 kVA(N+1)

  5. Contribution to Tier2s inATLAS + ALICE • http://www3.egee.cesga.es/gridsite/accounting/CESGA/country_view.html • Long term slide from 2006 for unavailable regular financing • From 2008 regular financing from grants (substantial capacity increase in all other Tier2s)

  6. RAW Capacities in FZU

  7. Center for Particle Physics in Prague • Delivering substantial capacities toD0 – second largest contribution to the experiment from external laboratories,ATLAS 2%, ALICE 7% (very good numbers), and others experiments • AUGER VO created in Prague • Support for Tier3 centers at Prague institutes and Universities • Today’s capacity23 kHEPSPEC2006, 2 800 cores 1,7 PB disc space • LCG capacities 250 000 cores, 100 PB disk,>140 centers worldwide -> Prague belongs to bigger centers AUGER 2800 jobs Running jobs D0 ATLAS ALICE 2011

  8. D0 Monte Carlo production and physics analysis • D0 MC 2010 • MC simulations in external laboratories • FZU 486M events, 2nd largest after IN2P3, 1300 concurrent jobs (2M jobs/year), 55 TB sent to FNAL • Physics analysis • PHD Theses – done in Prague

  9. Observation of a Centrality-Dependent Dijet Asymmetry in Lead-Lead Collisions at sNN= 2.76 TeVwith the ATLAS Detector at the LHC • Colleagues from Charles University (2 of 4 main authors) made the computing at our farm.

  10. Operation, Financing • Operation • Centre is operated by SAVT (computing department of FZU) • Together with other computing services for FZU • Our services run by 3-4 FTE • Contact person from each experiment in close contact with operation staff • Financing • FZU • Construction, power infrastructure (UPS, Generator), cooling by FZU, 20 MCZK in 2003/4 • Operation, electricity • HEP research grants • Computing capacities • Regular financing from 2008 (MoU with LCG)6 MCZK per year

  11. Conclusion • Long term activity starting in 2001 with European GRID project EDG • Most of personnel are it-professionals • Successful operation for experiments • Institute support for farm construction and operation • Grants for computing capacities • Visible Grid and non-grid computing services for HEP experiments and Czech collaborating institutes and physicists • Substantial support to our physicists and students in analysis competition
