The current state of the Worldwide LHC Computing Grid (WLCG) and the challenges that await the WLCG and the experiments at the Large Hadron Collider in terms of processing and storing ever-increasing data streams were presented by M. Litmaath (WLCG Operations Coordination Co-chair, CERN). T.A. Strizh (Deputy Director for Scientific Work, MLIT JINR) gave an overview of the development of the Tier1 centre at MLIT JINR for the CMS experiment from a prototype to a centre that has the world’s leading position in event processing within the CMS experiment. At present, JINR’s Tier1 is also used for processing data from the NICA experiments. V.V. Velikhov (Deputy Director for Information Technologies and Systems, NRC “Kurchatov Institute”) devoted his report to the status of the computing infrastructure of the NRC “Kurchatov Institute”. V.V. Kotliar (Head of the Laboratory of the Department of Mathematics and Computer Engineering, NRC “Kurchatov Institute” – IHEP) discussed the evolution of the WLCG Tier2 computing centre at the NRC “Kurchatov Institute” – IHEP from 2003 to 2023, and A.K. Kiryanov (Head of the Department of Information and Computing Resources and Technologies, NRC “Kurchatov Institute” – PNPI) enlarged upon the monitoring system of the PIK data centre, the main task of which is data storage and processing within experiments at the PIK nuclear reactor. E.M. Lavrischeva (Chief Researcher, ISP RAS) presented a description of the resource assembly apparatus using fundamental and general types of data and functions for converting transmitted non-equivalent, unstructured data (including Big Data) in the Internet environment. Different molecular devices based on DNA, which enable the solution of bioinformatics tasks, were considered by V.D. Lakhno (Scientific Leader, IMPB RAS, Pushchino). The talk by A.V. Bogdanov (Professor, Department of Fundamental Informatics and Distributed Systems, SPbU) discussed in detail solutions of partial differential equations with particular emphasis on a representation at the so-called “intermediate point”. This kind of representation opens the way for parallel algorithms. Two options for implementing a computational experiment, namely, with full parallelization and achieving the independence of modeling processes with interactive and graphical visualization, were presented in the report by A.B. Degtyarev (Professor, Head of the Department of Computer Modelling and Multiprocessor Systems, SPbU). Plenary talks on the rapidly developing technologies and methods of machine learning were also delivered at the conference. A.E. Shevel (Head of the Department of Computing Systems, Sector of High Energy Physics, NRC “Kurchatov Institute” – PNPI) spoke about the growing role of artificial neural networks in data processing for high-energy physics. D.E. Namiot (Senior Researcher, Laboratory of Open Information Technologies, MSU) reviewed approaches to the certification of machine learning models. A.V. Stadnik (Senior Data Analyst, Computer Vision Group of the Laboratory of AI and Neural Networks, Branch No. 11, OCRV Sirius) devoted his report to the investigation of the task of detecting objects of various sizes using a neural network model.

A new feature in the conference programme was the student scientific session, at which students who had passed the selection at the JINR Spring School of Information Technologies delivered talks on the results of their work. The GRID’2023 programme embraced two workshops. One of them, devoted to the issue of modeling and creating digital twins for new generation reactors, was organized jointly by MLIT JINR, FLNP JINR and the MBIR Consortium. The second workshop on computing for radiobiology and medicine was conducted by the JINR MLIT and LRB team together with Serbian colleagues. In addition, there were held round tables on the development of IT education with the participation of numerous representatives of universities and on the RDIG-M (Russian Data-Intensive Grid Certificate Authority) distributed infrastructure for data processing, storage and analysis within large-scale scientific projects in Russia. In total, 30 plenary and over 135 sessional talks were delivered within the conference. Fruitful discussions were held by the conference participants, new IT projects aimed at the development of distributed and high-performance computing were proposed, and new directions in collaboration between MLIT and organizations, universities of Russia and the JINR Member States emerged. Traditionally, during the conference, a boat trip along the Volga and Dubna rivers, followed by a barbecue in Ratmino, took place. At the closing of the conference, words of gratitude were expressed to the organizing committee for the high level of holding the conference. The presentations of the talks and photos are available at GRID’2023. Selected proceedings of the conference will be published in the Physics of Elementary Particles and Atomic Nuclei journal.
