JINR TIER-1 -LEVEL COMPUTING SYSTEM FOR THE CMS EXPERIMENT AT LHC: STATUS AND PERSPECTIVES JINR TIER-1 -LEVEL COMPUTING SYSTEM FOR THE CMS EXPERIMENT AT LHC: STATUS AND PERSPECTIVES Tatiana Strizh LIT, JINR

Tier 1 CMS center in JINR was initiated by the project “Creation of an Tier 1 CMS center in JINR was initiated by the project “Creation of an automated system for data processing of LHC experiments at Tier 1 level and provision of grid-services for distributed analysis of these data”, within the federal target program (FTP) of the RF Ministry of Education and Science “Research and developments on priority directions of the development of the scientific and technological complex of Russia on the years 2007 -2013”

The September 28, 2012 session of the WLCG Overview Board approved the plan of The September 28, 2012 session of the WLCG Overview Board approved the plan of creating a Tier 1 -level center in Russia. The project foresees a staged gradual implementation. The first stage ended in December 2012. A Tier 1 prototype was created at NRC “Kurchatov Institute” and at JINR. The next stage (November 2014) provides the final deployment of the complex and commissioning of the full-scale Tier 1 center in JINR.
