Presentation Transcript

  1. Atlas Analysis Infrastructure in Japan Hiroshi Sakamoto ICEPP, University of Tokyo

  2. Contents • Atlas Activity in Japan • Requirements on Analysis Infrastructure • Domestic Network • LCG Testbed • Future Plan

  3. Atlas Activity in Japan • Endcap Muon Trigger System (TGC) • Level 1 Trigger Simulation • Barrel SCT • Detector Geometry Description • Online System • Central Solenoid • Muon TDC

  4. Atlas Activity in Japan • Physics Analysis • Higgs: VBF • SUSY: Shoji Asai as a convener • Higher Level Trigger • Commissioning of Endcap Muon • Physics Analysis Tools Workshop 2006 • May 15th~19th, at University of Tokyo • 60 Participants (inc. Australia, China, Japan, Taiwan)

  5. Atlas Activity in Japan • 15 institutes ~ 90 researchers ~ 30 students • KEK(28), Tsukuba(4+4), Tokyo(13+14), TMU(1+0), Shinshu(3+1), Nagoya(New,1+0), Ritzumei(1), Kyoto(1+0), Kyoto-Kyoiku(1+1), Osaka(2+0), Kobe(7+6), Naruto-Kyoiku(1), Okayama(3+2), Hiroshima(1+0), Hiroshima-IT(1+2), Nagasaki-GS(2)

  6. Requirements on Analysis Infrastructure • Atlas Tier2 at ICEPP, Univ. Tokyo • Main analysis platform. • Tier3 sites (not yet defined) • KEK • Kansai area (Kobe)

  7. Domestic Network • SuperSINET • 10Gbps backbone • Tokyo, KEK, Tsukuba, Nagoya, Kyoto, Osaka, Hiroshima • 1Gbps connection to universities • Shinshu, Kobe, Okayama • Relatively short distance ~ Small RTT • 4ms ~ 20ms • Interactive session?

  8. 10Gbps Backbone Tokyo1 Tokyo2 Osaka Nagoya SuperSINET nodes SINET nodes

  9. Testbed Deployment • Platform for training • Middleware installation/configuration. • Development of user application • Tutorials/Exercises • Start between KEK and ICEPP • A part of joint R&D program • Extended to Kobe • EoI from Hiroshima-IT, Okayama, Nagoya

  10. Applications • Level 1 Trigger Simulation • Endcap Muon Trigger System. • Verification for every new release. • LCG Middleware Tutorial • Three day tutorial in December 2005 • 30 participants from Atlas Japan.

  11. Future Plan • Migration of testbed sites to official LCG ones • Human resource is limited. No need to operate two separate grids. • Must be part of LCG in order to access the Atlas Data. • Atlas-Japan LCG sites • Under APROC • Atlas-Japan VO support
