Abstract
The experiments at the Large Hadron Collider (LHC) at CERN (Geneva, Switzerland) played a leading role in scientific research not only in elementary particle physics and nuclear physics, but also in the field of Big Data Analytics. Global distributed system for processing, storage and analyzing data WLCG (Worldwide LHC Computing GRID) brings together the resources of about 180 computer centres in 50 countries, the total storage capacity is more than 1 Exabytes. Data processing and analysis is carried out using high-performance complexes (Grid), academic, national and commercial resources of cloud computing, supercomputers and other resources. JINR is actively involved in the integration of distributed heterogeneous resources and the development of Big data technologies to provide modern megaprojects in such high-intensity fields of science as high energy physics, astrophysics, bioinformatics and others. JINR is actively working on the construction of a unique NICA accelerator complex, which requires new approaches to the implementation of distributed infrastructure for processing and analysis of experimental data. The report provides an overview of major integrated infrastructures to support mega-projects and trends in their evolution. The report also presents the main results of the Laboratory of Information Technologies Joint Institute for Nuclear Research (JINR) in the development of distributed computing. A brief overview of the projects in the field of the development of distributed computations performed by LIT in Russia, CERN, the USA, China, JINR Member States. The analysis works on the integration of technology HPC, grid, cloud, BigData for large international projects.
Highlights
The Joint Institute for Nuclear Research (JINR) [1] is an international intergovernmental organization and is developing as a large multidisciplinary international scientific center incorporating basic research in the field of modern nuclear physics, development and application of cutting edge technologies, and university education in the relevant fields of knowledge
The future development of the basic computer infrastructure of the JINR is necessary for the success of the ambitious targets of the research carried out at JINR and collaborating organizations both in frames of the JINR research programmes, in particular the NICA (Nuclotron-based Ion Collider fAcility) megaproject [2], and within cooperation with the leading scientific and research centers (CERN, FAIR, BNL, etc.)
In the last few years, in the context of various works on organization of the computing for NICA, commissioning of the Tier1 center for the CMS experiment [3], as a part of the Worldwide Large Hadron Collider (LHC) Computing Grid infrastructure (WLCG) [4], implementations of a cloud computing structure and of a cluster for hybrid computations, the informationcomputing environment of JINR evolved in a set of stand-alone structures that have a common engineering and networking infrastructures
Summary
Support of this fully functional infrastructure is the major task of the Laboratory of Information Technologies (LIT). In the last few years, in the context of various works on organization of the computing for NICA, commissioning of the Tier center for the CMS experiment [3], as a part of the Worldwide LHC Computing Grid infrastructure (WLCG) [4], implementations of a cloud computing structure and of a cluster for hybrid computations, the informationcomputing environment of JINR evolved in a set of stand-alone structures that have a common engineering and networking infrastructures. Multifunctional Information and Computing Complex (MICC) [5] of JINR currently has the following basic components:. The grid center resources of the MICC JINR are a part of the WLCG infrastructure, developed for the LHC experiments
