Ivanov (LIT JINR) GRID’2012, JINR, Dubna Future: basic principles and general perspectives The formation of a unified Grid-environment of the JINR Member States is a basis of the 7-year plan within the direction Networks. Computing. Computational Physics. There are three main levels within the Grid-environment: network, resource and applied. The network level deals with high-speed backbones and telecommunication links. The resource level consists of high-performance computing clusters, and data storage systems joined in a unified Grid and cloud environment with the help of basic software and middleware. The applied level involves research topics the solutions of which have been adapted to the Grid&cloud environment in frames of corresponding virtual organizations. V.V. Ivanov (LIT JINR) GRID’2012, JINR, Dubna Current hot topics are clouds, multicore, virtualisation, hybrid computing technologies Will they still seem important in 2020? 43 V.V. Ivanov (LIT JINR) GRID’2012, JINR, Dubna Applied level developments of the JINR Grid-environment (I) 1. The applied level covers the user applications working in a virtual organization (VO) environment which comprises both users and owners of computing resources. 2. In the existing Grid-systems, a VO defines a collaboration of specialists in some area, who combine their efforts to achieve a common aim. 3. The virtual organization is a flexible structure that can be formed dynamically and may have a limited life-time. VOs working within the WLCG project are the VOs on the LHC experiments - ATLAS, CMS, Alice, LHCb, the first three being carried out with the noticeable and direct participation of the JINR. Nowadays, as a Grid-segment of the EGEE/RDIG, the JINR CICC supports computations of the virtual organizations registered in RDIG ( LHC experiments, BioMed, PHOTON, eEarth, Fusion, HONE, Panda. In the future, as the interest arises at a large-scale level, VOs can be organized at JINR in the fields of nuclear physics and condensed matter physics and, most probably, in the new promising direction related to the research of the nanostructure properties. V.V. Ivanov (LIT JINR) GRID’2012, JINR, Dubna Applied level developments of the JINR Grid-environment (II) The creation of new VOs gets possible and necessary under maturation of the algorithmic approaches to the problem solution, the development of corresponding mathematical methods and tools: methods and tools for simulation of physical processes and analysis of experimental data software and computer complexes for experimental data processing; numerical methods, algorithms and software for modeling complex physical systems; methods, algorithms and software of computer algebra; new computing paradigms; adaptation of specialized software for solving problems within the Gridenvironment.
