The Compact Muon Solenoid (CMS) is a high-performance general-purpose detector at the Large Hadron Collider (LHC) at CERN. A distributed data analysis system for processing and further analysis of CMS experimental data has been developed and this model foresees the obligatory usage of modern grid-technologies. The CMS Computing Model makes use of the hierarchy of computing centers (Tiers). The Joint Institute for Nuclear Research (JINR) takes an active part in the CMS experiment. In order to provide a proper computing infrastructure for the CMS experiment at JINR and for Russian institutes collaborating in CMS, Tier-1 center for the CMS experiment is constructing at JINR. The main tasks and services of the CMS Tier-1 at JINR are described. The status and perspectives of the Tier1 center for the CMS experiment at JINR are presented.

Keywords: grid computing, CMS experiment, CMS Tiers
