The main task in creating a computing infrastructure of any large experiment is predictive modelling of data storage and processing centres. A software complex is developed at the Meshcheryakov Laboratory of Information Technologies, which allows simulating processes of data handling to find out both how the data storage and processing infrastructure will work with the available computing...
In 2021, accounting systems that make it possible to visually display various parameters of the functioning of computing clusters based on the JINR CMS Tier-1 and JINR WLCG Tier-2 Grid sites were put into operation at MLIT. The batch system, intended for performing calculations of the JINR Laboratories’ experiments, operates on the Toque/Maui software, and the accounting system has not been...
The efficient operation of large physics experiments is ensured by many factors, one of which is software used for both online and offline systems. A set of software systems is also being implemented for the first experiment of the NICA project, a fixed target BM@N setup, where they are used, among other things, for centralized storage, access and exchange of necessary information. The report...
The condition database of the BM@N experiment, the first experiment of the NICA megaproject, is used as a central location for storing vital experiment metadata, including session and run information, detector and subsystem parameters, and description of simulated event files. For an effective work with the database in the existing software environment, a set of various tools and services are...
Modern information technologies make it possible to automate the control process and switch to unmanned (crewless) driving. For example, crewless ships are already being created in maritime transport which are capable of solving the problem of cooperative maneuvering without human help automatically[1]. In spite of the positive results, the automation of the process of managing moving objects...
The Event Metadata System (EMS) developed for BM@N, a fixed target experiment of the NICA (Nuclotron-based Ion Collider fAcility) project has been designed to store and index event records for particle collisions obtained at the BM@N facility. The system enables to quickly search for a required set of physics events based on various criteria for further physics analyses. The main interfaces to...
In recent years, deep learning has been applied to different tasks in food recognition field. Number of interesting solutions have been proposed. Due to the complexity of background’s food, the problem of pattern recognition on a limited data set is still a challenging problem. Experiments were conducted with a self-collected set of data on trays in the canteen, containing images of various...
Advanced trends in computer vision and automotive engineering seek to control traffic conditions as much as possible to keep drivers safer, or to replace them at all. In addition to autopilot, traffic control is used in mapping, to monitor road infrastructure and its inventory, which allows controlling the functioning and maintaining the correct location of road elements. Such systems need...
The ML/DL/HPC ecosystem deployed on the HybriLIT Heterogeneous Computing Platform (Meshcheryakov Laboratory of Information Technologies JINR) on top of JupyterHub, allows you to conduct research not only in the field of machine learning and deep learning, but also allows you to develop and implement program modules in Python, as well as to carry out methodical computations. Using the example...
The BIOHLIT information system (IS) for analyzing behavioral and pathomorphological changes in the central nervous system when studying the effect of ionizing radiation on laboratory animals. Information system is being jointly developed by specialists from MLIT and LRB JINR.
The information system provides interfaces for: storing experimental data in a single information space (for...
The SRC experiment searches for short-period two-nucleon correlations using the detector subsystems of the BM@N facility. Successful experiments of this kind require an easy-to-operate, reliable system for controlling and monitoring the slowly changing parameters of the experimental hardware. Slowly changing parameters of experimental hardware that require constant monitoring are high and low...
Execution of one computing job demonstrates that software is correctly working. But, when the same job has to be executed thousands of times, it may cause different issues. Nowadays special distributed heterogeneous computing infrastructures are widely used for this type or workload. Main issue when running big workloads on them is network limits. These limits may be imposed in different...
One of the tasks of the JINR organizational activity is to conduct excursions in the Institute's laboratories for different types of target audience and age groups. The organization of each excursion goes through a number of steps related to negotiation of excursion time, availabiolity of the facility and the guide. All negotiation were carried out through telephone and email conversations...
