JINR-KIPT Common Activities in CMS Computing Support • Cooperation between JINR and KIPT (Kharkov, Ukraine) has been supported by 3 grants of Russian Foundation for Basic Research (RFBR) and Ukrainian Academy of Science: • 08-07-90410-Ukr_a (2008-2009) “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)“Support and development of LIT JINR and NSC KIPT grid-infrastructures for CMS distributed data processing during the first two years of LHC operation”– completed • 12-07-90402-Ukr_а(2012-2013) “Data processing at the LIT JINR and NSC KIPT T2-centers of the CMS grid infrastructure at high rate of the Large Hadron Collider luminosity increase” – in a progress

  24. RDMS Remote Operation Centres JINR ROC was founded in 2009 as a part of GRID-based JINR Tier-2 MSU/IHEP ROCs were started-up two years after • Monitoring of detector systems • Data Monitoring / Express Analysis • Shift Operations (except for run control) • Communications of JINR shifter with personal at CMS Control Room (SX5) and CMS Meyrin centre • Communications between JINR experts and CMS shifters • Coordination of data processing and data management • Training and Information

  25. Summary RDMS Tier2 sites contribute in the CMS Data Processing and Analysis Tasks Tier-2 sites are satisfied to CMS Computing Requirements they are involved actively into data processing and analysis (as of CMS Physics Groups associated sites) CMS Regional Operation Centers in JINR/MSU/IHEP/FIAN are operated for remote monitoring of detector systems and data express-analysis There is still a number of problems (technical, financial etc.) preventing RDMS Tier2 sites to increase their resources and operation stability A stable and successful operation of several RDMS CMS Tier2 centers and years of operating experience lead to creation the CMS Tier-1 center in Russia as an integral part of the central data handling service of the CMS Experiment (CMS Tier-1 in Dubna)
