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

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)
