JINR Grid Infrastructure: Status and Plans

The JINR grid infrastructure was created in 2003 at the Meshcheryakov Laboratory of Information Technologies and has been successfully developed ever since. The participation of JINR scientists in the experiments at the Large Hadron Collider (LHC) at CERN entailed the creation of computing clusters at JINR, which are integrated into a distributed computing environment for processing and storing hundreds of petabytes of data obtained from the LHC experiments. In this regard, the Tier1 center for the CMS experiment, being among the best worldwide, and the Tier2 center, which is the best in Russia, are particularly notable. At present, both of these centers serve the experiments at the NICA complex. The current state of the JINR grid infrastructure and its future development are presented.
