  3. ME1/1 ME SE EE HE HF FS RDMS Participation in CMS Construction RDMS Full Responsibility RDMS Participation

  4. RDMS Participation in CMS Project • Full responsibility including management, design, construction, • installation, commissioning, maintenance and operation for: • Endcap Hadron Calorimeter, HE • 1st Forward Muon Station,ME1/1 Participation in: Forward Hadron Calorimeter,HF EndcapECAL,EE Endcap Preshower,SE Endcap Muon System,ME Forward Shielding,FS

  5. RDMS activities in CMS • Design, production and installation • Calibration and alignment • Reconstruction algorithms • Data processing and analysis • Monte Carlo simulation H (150 GeV)  Z0Z0  4 

  6. small centres Santiago RAL desktops portables Tier-2 Weizmann Tier-1 MSU IN2P3 LHC Computing Model • Tier-0 (CERN) • Filter  raw data • Reconstruction  summary data (ESD) • Record raw data and ESD • Distribute raw and ESD to Tier-1 IC JINR ITEP FNAL Cambridge CNAF Budapest Prague FZK IHEP PIC TRIUMF ICEPP BNL Legnaro CSCS • Tier-1 • Permanent storage and management of raw, ESD, calibration data, meta-data, analysis data and databases  grid-enabled data service • Data-heavy analysis • Re-processing raw  ESD • ESD-AOD selection • National, regional support Rome Kharkov PNPI Minsk NIKHEF • Tier-2 • Simulation, digitization, calibration of simulated data • End-user analysis

  7. Tier 0 – Tier 1 – Tier 2 Tier-0 (CERN): • Data recording • Initial data reconstruction • Data distribution Tier-1 (11 centres): • Permanent storage • Re-processing • Analysis Tier-2 (>200 centres): • Simulation • End-user analysis 7

  9. RCMS CMS T2 association Now Future interest Analysis Groups Exotica: T2_RU_JINR Exotica: T2_RU_INR HI: T2_RU_SINP QCD: T2_RU_PNPI Top: T2_RU_SINP FWD: T2_RU_IHEP Object/Performance Groups Muon: T2_RU_JINR e-gamma-ECAL: T2_RU_INR JetMET-HCAL: T2_RU_ITEP 9

  10. CMS T2 requirements Basic requirements to CMS VO T2 sites for Physics group hosting: a) info on contact persons responsible for site operation b) site visibility (BDII) c) availability of CMSSW actual version d) regular file transfer test “OK” e) Certified links with CMS T1: 2 up and 4 down f) CMS job robot test “OK” g) disk space ~ 150-200 TB for: - central space (~30 TB) - analysis space (~60-90 TB) - MC space (~20 TB) - local space (~30-60 TB) - local CMS users space (~1 TB per user) h) CPU resources ~ 3KSI2K per 1 TB disk space, 2GB memory per job 10 10

  11. T2 readiness requirements • Site visibility and CMS VO support • Availability of disk and CPU resources • Daily SAM availability > 80% • Daily JR-MM efficiency > 80% • Commissioned links TO Tier-1 sites ≥ 2 • Commissioned links FROM Tier-1 sites ≥ 4 11

  12. CMS T1 – RU T2 link status 13

  13. Available resources 14

  14. RDMS CMS T2 readiness T2_RU_ITEP: Ready T2_RU_SINP:Ready T2_UA_KIPT:Ready T2_RU_JINR: Ready 15

  15. CMS computing in 2009 year • Computing scale test (together with ATLAS) • May – June 2009 • Cosmic run data processing and analysis • July – September 2009 • Big MC samples production • Starting in July 2009 • LHC data processing and analysis • Starting in October 2009 16

  16. STEP 09 results Test of data transfer from CMS T1s to T2s RU_SINP, RU_JINR, RU_ITEP were participated High transfer rate and quality were achieved SINP max 101 MB/s 17

  17. CMS T1-CH-CERN

  18. Russia Normalized CPU time per VO (August 2009)

  19. Request for RDMS CMS T2s upgrade CMS request to upgrade by Jan. 2010: Total disk space – up to 1300TB Total CPU - up 4500kSI2K (~1800 job slots) First priority tasks: • Complete T1<->T2 link certification for INR, IHEP, PNPI • Improve stability of operation (“availability” & “readiness”) • Full test of MC prod and analysis jobs running in parallel • Increase disk space at each of T2 up to 150 TB • Increase number of CMS job slots at each of T2 up to 200 20

  20. Summary ITEP, JINR, SINP and UA_KIPT- in a stable state RRC_KI – all sw required is installed, the links are certified but not in a stable state INR – not all the links required are certified – to be accomplished in a month or earlier PNPI – now installed 1 Gbs external channel; certification of link is in process IHEP – now installed 1 Gbs external channel; certification of link is in process ITEP, JINR and SINP support group space for MUON, JetMET/HCAL, HI and Exotica – thus the main efforts were applied to certify links to/from these institutes 21
