  1. ITEP participation in the EGEE project NEC’2005, Varna, Bulgaria Ivan Korolko (ITEP Moscow)

  2. ITEP history Institute for Theoretical and Experimental Physics was founded on December 1, 1945. the heavy-water reactor was run in 1949 in 1961 the 7-GeV proton synchrotron started operating. It was the first Russian proton accelerator using the strong focusing principle. (small prototype of the biggest Russian 76-GeV machine built later in Protvino). Now ITEP is Russian scientific centers aimed at studying nuclear physics and physics of elementary particles. Institute occupies the area of the old eighteenth century estate "Cheremushki".

  3. ITEP research program • Theoretical study of the properties and interactions of elementary particles and atomic nuclei and astrophysical aspects; • Study of hadron-hadron and hadron-nuclear interactions and resonance systems; • Investigation of fundamental interactions using colliding beams and high-energy accelerators; • Study of electroweak interaction at accelerators and low-background facilities; • Investigation of low-energy interactions; • Solid-state physics, physical chemistry and superconductivity; • Nuclear fusion at powerful heavy-ion and electromagnetic drivers; • Development of new proton therapy methods and construction of a positron-electron tomograph for medical diagnostics; • Development of new methods of proton and heavy-ion acceleration; • Development of a new generation of safe nuclear-power facilities;

  4. International collaboration DESY (Hamburg) - ARGUS, H1, HERA-B CERN (Geneva) - AMS, CHORUS, L3 ATLAS, ALICE, CMS, LHCb FNAL (Batavia) - D0, E781(SELEX) GSI (Darmstadt) - CBM And many others

  5. ITEP in EGEE ITEP participation in EGEE project has started in 2004 • NA2 • NA3 • NA4 • SA1 ITEP is responsible for the support of LHCb applications ITEP is operating user-support centre in Russia

  7. User support Supports Russian language Connected with FZK centre in Karlsruhe

  8. 1 Gb 32 (LCG) + 32 (usual) ITEP LHC computing farm BATCH nodes CPU: 64 PIV-2.4GHz (hyperthreading) RAM: 1 GB Disks: 80 GB Mass storage Disk servers: 6 x 1.6 TB + 1 x 1.0 TB + 1 x 0.5 TB 100 Mb CERN

  9. ITEP LHC computing farm main components A. Selivanov (ITEP-ALICE)a head of the ITEP-LHC farm 64  Pentium IV PC modules(01.01.2004)

  10. Project CPU Time Jobs ALICE 3038 days 18:40:25 15918 ATLAS 01:25:50 9 CMS 1310 days 01:02:55 1605 LHCB 16884 days 08:08:06 9681 SELEX 1551 days 21:29:04 1485 Total 22784 days 23:24:00 28689 ITEP LHC farm usage in 2004

  11. ITEP LCG farm usage in 2005 Smooth operation of ALICE, CMS and LHCb

  12. LHCb DC04 statistics 3 months – 65 TB of data produced, transferred and replicated 185M events, 425 CPU years across 60 sites

  13. ALICE DC04 statistics

  14. DC04 Summary Quite visible participation in ALICE and LHCb DCs ALICE → ~5% contribution (ITEP part ~70%) LHCb → ~5% contribution (ITEP part ~70%) With only 64 CPUs Observed problems reported to colleagues in collaborations More attention to LCG now Distributed analysis – very different pattern of work load connectivity with CERN and TIER1 centers is an issue !

  15. Advertising GRID ideas • Russian VO PHOTON for SELEX colleagues was organized in 2005 (Dolgolenko) • Regional centre for AMS (VO in preparation) • Collaboration with CBM project (GSI, Darmstadt) • ITEP theory department is very interested ITEP physicists are starting to use LCG resources for their every day work. LHCb group has performed simulations of light collection efficiency in LCG (~20K jobs finished in 2 days)

  16. Plans for the nearest future Further support of LHC experiments Data Challenges becomes a trivial task running automatically Increase significantly the power of ITEP farm in 2006 special computing facility is organized in ITEP current installation occupies only ~5% Concentrate on distributed analysis (test GANGA) connectivity with CERN and TIER1 centers is an issue !
