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), P 11 -2010 -11, Dubna, 2010, http: //www 1. jinr. ru/Preprints/2010/011%28 P 11 -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 17

Summary IHEP, INR, ITEP, JINR, PNPI, SINP and UA_KIPT are in a stable state RRC_KI – was not in a stable state but by the moment the situation has been significantly improved Current task is to define status of the RDMS CMS sites in context of the new CMS requirements to CMS T 2 18
