The main directions of the activities at the Meshcheryakov Laboratory of Information Technologies (MLIT) are connected with the provision of networks, computer and information resources, as well as mathematical support of a wide range of research at JINR in high energy physics, nuclear physics, condensed matter physics, etc.
More information about the MLIT activities
MLIT activities in network, computer and information resources includes the following tasks: provision of the Institute and JINR Member States with high-speed telecommunication channels; development of a high-speed, fail-safe and protected computer network at JINR; support of the distributed high-productive computer infrastructure and mass memory system; provision of informational and software support of the scientific and industrial activities of the Institute; development of the enterprise information system: elaboration of the JINR grid-segment and its introduction into the world grid-structure.
MLIT possesses a fast communication channel “Dubna-Moscow” on the basis of the DWDM technology with starting capacity of 20 Gbit/s. The JINR core network that overlaps all laboratories and divisions of JINR in a single computer network is constructed with the Gigabit Ethernet technology, with data transfer speed of 10 Gbit/s.
The JINR Central Information Computer Complex (CICC) is the core of the computer infrastructure of the Institute. CICC JINR has powerful high-productive computer resources that are integrated into the world computer networks by means of the high-speed communication channels.
The Institute grid-segment developed on the CICC basis is an important element of the RDIG (Russian Data Intensive Grid), WLCG (Worldwide LHC Computing Grid) and EGI (European Grid Infrastructure).
It provides support for virtual organization of international projects, including those at the LHC. Over 5 million tasks are solved annually at CICC JINR. Computing environment and data storage systems are controlled by the basic software that allows the use CICC resources in both international projects for distributed calculations (ATLAS, ALICE, CMS, PANDA, CBM, BES, NICA/MPD, etc.) and “home” research by JINR users.
A centre of the Tier-1 level is developed on the basis of CICC JINR for the CMS experiment (LHC). The Тier-1 centre will be used as a part of global system of experimental data processing, as well as handling the data of events’ simulation that arrives from the centre Tier0 (CERN), and the centres Tier-1 and Tier-2, the global gridsystem WLCG for the experiment CMS.
Today MLIT JINR works actively to integrate the distributed calculations system for the solution of large-scale tasks using the Big Data Technology. A cloud infrastructure is developed at the laboratory that provides users with cloud services. A distributed training research grid-infrastructure is developed at MLIT to educate students and specialists that is represented by popular modern techniques of distributed calculations.
A heterogeneous cluster «HybriLIT» is introduced into CICC JINR to conduct calculations with parallel programming technology.
Mathematical support of experimental and theoretical research conducted with direct JINR involvement includes research on the advanced level in computational mathematics and physics. The aim of these studies is the development of mathematical methods, algorithms and programmes for numerical and symbol-numerical simulation of physical processes, experimental data processing and analysis with the latest computational hardware.
