GRID is a software-hardware infrastructure, providing safe, compatible, ubiquitous and inexpensive access to considerable processing power resources. It may be treated as a “virtual supercomputer” composed from clusters interconnected via a net, and weakly bounded heterogenous computers running together to complete a host of tasks. From a network-based company viewpoint - GRID is an open standardized environment, providing a flexible, secure, cooperative sharing of processing resources, as well as of data storage, which is a constituent part of this medium within one virtual organization.
It's a form for distributed calculations with a dynamic (during applications' run-time) selection, on demand sharing and integration of topologically separated autonomic resources, considering their availability, performance, cost, and specific processing requirements as well as an organization policy. This technology is being applied to solving scientific and mathematical tasks that need substantial processing power. GRID-processing is being used in commerce infrastructure as well - for solving resource-intensive tasks, like economic forecasting, seismic analyses, new drugs development and their properties study.
GRID AT JINR
JINR GRID is intended for large bulks of data coming from LHC (Large Hadron Collider) processing. Two GRID-sites are built at JINR: the 1st level resource centre (T1_RU_JUNR) for CMS experiment and the 2nd resource centre (JINR-LCG2) for ATLAS, Alice, CMS, LHCb, STAR, BES, COMPASS and other experiments. The sites are completely integrated into the global (world) WLCG (Worldwide LHC Computing Grid) project grid infrastructure.
