CRIC Information System Researchers from the Budker Institute of Nuclear Physics, Siberian Branch of the Russian Academy of Sciences (INP SB RAS, Novosibirsk) with the participation of JINR employees have developed the CRIC (Computing Resource Information Catalog) information system, which is one of the key components for building a distributed system for processing experimental data from the SPD Experiment at the NICA Accelerator Complex. The information system allows integrating computing centres to process large amounts of statistics of experimental data.. The INP SB RAS researchers started developing the CRIC Information System in 2016 for the experiments of the Large Hadron Collide (LHC) at CERN. CRIC is based on the previous system operating at CERN, AGIS (ATLAS Grid Information System), which was also created by the INP SB RAS team. Employees of the Laboratory of Information Technologies at JINR participated in engineering some parts of the AGIS System and refining its interfaces as part of joint work for the ATLAS Experiment. The CRIC System will enable configuration of the components of the experimental data processing system and provide description of the topology of the distributed computing infrastructure. The information system is a link between services and infrastructure. In addition, it provides certain information for monitoring and resource accounting systems. “The expected volume of experimental data is measured in tens of petabytes per year, which puts this experiment on a par with experiments at the LHC. Naturally, the processing of experimental data, including modelling of physical events, is carried out in a geographically distributed computing environment, with CRIC as one of its key systems,” Danila Oleinik commented. The scientist clarified that CRIC is a component of the integrated distributed data processing system of the SPD Experiment. Thus, MLIT JINR specialists make a major contribution to the refinement and commissioning of the PanDA Load Management System and the Rucio Data Management System for the needs of SPD. Konstantinov Petersburg Nuclear Physics Institute (PINP) of the Kurchatov Institute National Research Centre (Gatchina) actively participates in the development of geographically distributed data processing infrastructure. Danila Oleinik explained that the organization of distributed data processing for modern experiments includes the use of a variety of specialised software systems, with almost each product being individually refined and adapted to the tasks of a specific experiment. “Based on the experience, knowledge, and expertise of the MLIT team, we can not only use existing solutions, but also develop systems of the new generation,” the scientist noted.
