The project of launching Tier1 at JINR In November, 2011 at the suggestion of A.A. Fursenko at a session of the Committee on Russia-CERN cooperation, a decision was accepted on the creation in Russia of a Tier1-level center for LHC experiments on the base of NRC "Kurchatov institute" and JINR. On September 28, 2012, a session of the Supervisory Council of WLCG project approved a work schedule on the creation of Tier1 in Russia. First stage (December, 2012) - creation of a prototype of Tier1 at NRC KI and at JINR. Second stage (November, 2013) - installation of equipment for the base Tier1 center, its testing and finishing up to required functional characteristics. Third stage (March, 2015) – finalization of this complex and commissioning a full-scale Tier1 center for СМS in JINR In the sequel, a systematic increase of computing capacity and data storage is needed in accordance with the experiment requirements. the ex The details on Tier1 in at JINR see in today’s talk of Tatiana Strizh “JINR TIER-1 Centre for the CMS Experiment at LHC.”

CMS data transfers to/from RDMS CMS sites

08/10/09 Summary The main achievement of this year is a start-up of the CMS Tier1center at JINR in a full volume and its stable operation RDMS sites contribute in the CMS Data Storage, Processing and Analysis Tasks, in particular 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 There is still a number of problems (technical, financial etc.) preventing RDMS Tier2 sites to increase their resources and operation stability. By the moment not all RDMS T2 sites are satisfied to CMS Computing Requirements 19 19
