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

Summary
RDMS Tier2 sites contribute in the CMS Data Processing and Analysis
Tasks
пѓћ Tier-2 sites are satisfied to CMS Computing Requirements
пѓћ they are involved actively into data processing and analysis (as of
CMS Physics Groups associated sites)
пѓћ CMS Regional Operation Centers in JINR/MSU/IHEP/FIAN are
operated for remote monitoring of detector systems and data expressanalysis
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)
