Example of Physics analysis with GRID in the CMS Experiment with Participation of Russian
Physicists
Measurement of the EW Z boson and two jets in pp collisions at √s = 7 TeV has been carried out using an integrated luminosity of 5 fb−1. σ (7 TeV)= 154 ± 24 (stat.) ± 46 (exp. Syst.) ± 27 (th. syst.) ± 3 (lum.) fb (mll > 50 GeV, pTj > 25 GeV, |η j|< 4.0, mjj >120 GeV)
Data and Monte-Carlo simulated events are distributed among N sites
Job is prepared at UI with CRAB submission toolinstalled (CMS SW on top of LCG middleware)
Run CRAB jobs: job is going to the site where events(Data or MC) are located
Monitoring through Dashboard (CERN IT tool)

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

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 Tier2 sites contribute in the CMS Data Processing and Analysis Tasks
Þ Tier-2 sites are satisfied to CMS Computing Requirements
Þ they are involved actively into data processing and analysis (as of
CMS Physics Groups associated sites)
Þ 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)
