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:  Ukr_a ( ) “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), P , Dubna, 2010,  Ukr_а ( ) “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  Ukr_а ( ) “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

RDMS Remote Operation Centres  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 18 JINR ROC was founded in 2009 as a part of GRID-based JINR Tier-2 MSU/IHEP ROCs were started-up two years after

Summary RDMS Computing infrastructure allows a proper support of the CMS Data Processing and Analysis Tasks  Tier-2 sites are fully 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 A few sites want for increasing of their resources and operation stability A stable and successful operation of several RDMS CMS Tier2 centers and years of operating experience force us to the proposal to create the LCG Tier-1 center as an integral part of the central data handling service of the LHC Experiments in Russia (CMS Tier-1 in Dubna)
