The SPD (Spin Physics Detector) is a planned spin physics experiment in the second interaction point of the NICA collider that is under construction at JINR. The main goal of the experiment is the test of basics of QCD via the study of the polarized structure of the nucleon and spin-related phenomena in the collision of longitudinally and transversely polarized protons and deuterons at the...
Since many years, the Worldwide LHC Computing Grid (WLCG) has provided
the distributed computing infrastructure for the CERN Large Hadron Collider
experiments. During that time, it has seen steady evolution in technologies
as well as growth, to deal with ever increasing data rates. Those trends
need to be made to continue, to allow the WLCG to take on High-Luminosity
LHC data volumes as...

Recently, the branch of mathematics associated with functional integration has been rapidly developing. For a long time it was a means of constructing perturbation theory and solving applied problems. However, recently it has become clear that this can be a very effective tool for high-performance algorithms creation. Moreover, it may be the only tool for developing algorithms for quantum...
Artificial Neural Networks in High Energy Physics data processing (succinct survey) and probable future development
Abstract
The rising the role of Artificial Neural Networks (ANN) as part of machine learning/deep learning (ML/DL) in High Energy Physics (HEP) and related areas can be seen last decades. Several reasons for rising the role of ANN were observed. The...
Machine learning systems are today the main examples of the use of Artificial Intelligence in a wide variety of areas. From a practical point of view, we can say that machine learning is synonymous with the concept of Artificial Intelligence. In some works, this definition is somewhat limited, and they only talk about artificial neural networks and deep learning in the context of artificial...

Recently, the landscape of computational infrastructure is in dramatic changes under the pressure of application requirements. The suit of the properties of modern applications can be summarized as follows: distributed, self-sufficient, work in real time, elastic, cross-platform, actively interact and synchronize, and are easy to update. The definitions of these terms are in [1]. For further...
We are investigating the quantum dynamics of a well-collimated electron beam transmitting through planar channels of the Si crystal. Electron states were represented by wave packets, while the electron beam was treated as an ensemble of noninteracting wave packets. The evolution of electron states was obtained using the method of Chebyshev global propagation, specifically modified to give...
The advantages of cloud technologies allowed the latter to occupy a certain niche in the field of scientific computing. Around decade ago following that trend a cloud infrastructure had been deployed at JINR and later in the scientific organizations of the its Member States. These cloud resources were integrated into a Distributed Information and Computing Environment (DICE) to combine...
Modern systems and applications are increasingly distributed due to the growing performance, scalability and availability requirements. Distributed computing allows to flexibly aggregate the resources of individual machines into scalable computing infrastructures with required characteristics. However, distributed systems are hard to build, test and operate because of their asynchronous and...
