  3. Physics groups association RU_JINR - Muons and Exotica RU_SINP - Heavy Ions RU_ITEP - JetMET/HCAL UA_KIPT - Higgs

  4. RDMS CMS T2 association Now Future interest Analysis Groups Exotica: T2_RU_JINR Exotica: T2_RU_INR HI: T2_RU_SINP QCD: T2_RU_PNPI Electroweak: T2_UA_KIPT 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

  5. 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) in grid 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 (~60-100 TB) - MC space (~20 TB) - local space (~30-60 TB) - local CMS users space (~2 TB per user) h) CPU resources ~ 3KSI2K per 1 TB disk space, 2GB memory per job 5

  6. T2 readiness requirements • Site visibility and CMS VO support • Availability of disk and CPU resources • Daily SAM availability > 80% • Daily JR efficiency > 90% • Commissioned (active) links TO Tier-1 sites ≥ 2 • Commissioned (active) links FROM Tier-1 sites≥ 4

  7. Status of RDMS sites readiness on 18 May, 2011( R –Ready; NR – Not Ready)

  8. RDMS CMS T2 Readiness (January – May, 2011)

  9. All CMS sites status of readiness (January-May, 2011)

  10. Total Number of CMS Jobs at RDMS CMS sites January, 2010 – April, 2010 and January, 2011 – April, 2011 2010 year 768,240 jobs 998,540 jobs 2011 year 10

  16. CMS T1  RU T2 active links status

  17. Regular European/Asian CMS-Tier2 Support Meetings conducted at CERN provide RDMS T2 sites a real support Many thanks to Giuseppe Bagliesi, Jose Flix Molina and Peter Kreuzer European/Asian CMS-Tier2 Support Meetings

  18. JINR-KIPT Common Activities in CMS Computing Support • Cooperation between JINR and KIPT (Kharkov, Ukraine) has been supported by 2 grants of Russian Foundation for Basic Research (RFBR) and Ukrainian Academy of Science: • 08-07-90410-Ukr_a (2008-2009 гг.) “Preparation of LIT JINR (Dubna) and NSC KIPT (Kharkov) computing centers for CMS (CERN) distributed data analysis on the base of grid technologies” – completed (see: Bunetsky O. O. et al. , Preparation of NSC KIPT and JINR Grid-Infrastructures for Data Analysis at the CMS Experiment (CERN), P11-2010-11, Dubna, 2010,http://www1.jinr.ru/Preprints/2010/011%28P11-2010-11%29.pdf) • 10-07-90400-Ukr_а (2010-2011 гг.)“Support and development of LIT JINR and NSC KIPT grid-infrastructures for CMS distributed data processing during the first two years of LHC operation”– in a progress

  19. Summary IHEP, INR, ITEP, JINR, PNPI, SINP and UA_KIPT are in a stable state RRC_KI – is not in a stable state (but last several months the situation has been significantly improved) Current tasks: to complete T1<-T2 link certification with all CMS T1s to improve stability of operation (“availability” & “readiness”) to increase disk space at each of T2 up to 150 TB to increase number of CMS job slots at each of T2 up to 200
