At present, the “Govorun” supercomputer is used to solve different tasks facing JINR. One of the main tasks is modeling of physical events for the NICA megaproject. A peculiarity of such tasks is to work with large amounts of simulated data, amounting to hundreds of terabytes. To speed up the processing of big arrays of data, a hierarchical hyperconverged system of data processing and storage...
For effective work on constructing the BM@N experiment of the NICA project, it is necessary to use tools for centralized storing and exchanging of information, which should simplify the search for the required information, as well as ensure its relevance and consistency, especially when an international collaboration is being formed around the experiment. In the process of designing the...
The evaluation of the performance of computing resources is important for workload distribution and workload planning. It is usually done with standard benchmark tools. The most well-known benchmark in grid infrastructures in High Energy Physic is HEP-SPEC06. This benchmark is based on industrial benchmark SPEC06. Running of HEP-SPEC06 takes a substantial amount of time but gives a precise...
For a significant reduction of time spent on research to obtaining meaningful results in scientific domains, the computer resources of the Joint Institute for Nuclear Research (JINR) and some organizations of its Member States were integrated into a distributed information and computing environment (DICE). A technical possibility for running tasks in that environment was implemented for the...
Currently, there is a significant increase in the number of sources of scientific and technical information on the Internet, which complicates its high-quality processing by scientists. At the same time, the use of cloud computing environments is gaining popularity in organizations.
The Joint Institute for Nuclear Research (JINR) has its own cloud computing environment developed by the...
The saas.jinr.ru service is an attempt to simplify the usage of the JINR Multifunctional Information and Computing Complex (MICC). The project mainly focuses on evaluating the potential of problem-oriented web-interfaces and ways to ease the access to all of the major computing facilities of the MICC. The talk will cover the project’s current state, including the service architecture and...
Inter-disciplinary research and open data access are big trends in modern science. Globalization facilitates the exchange of experiences and ideas between different domains of knowledge, and allows us to expand the horizons of our understanding of the processes taking place in nature and society. To make this happen, aggregated data access systems are being established to link together...
This work is aimed at description of issues we face conducting radiobiology experiments at Laboratory of Radiobiology. Our investigations are based on organismic and cell levels. This work shows the opportunities to apply the modern IT technologies for storing the data (photo&video) of histological researches and after behavioral tests, optimization the work of the software, automatization of...
The report presents the status of work on the joint project of LIT and LRB on the creation of a service for
studying behavioral and pathomorphological changes in the central nervous system of biological objects.
To conduct modern scientific research in the field of radiobiology, it is usually necessary to use many
different modern approaches to data analysis, image and video processing such...
The report presents the status of work on the joint project of LIT and BLTP on the creation of a virtual research environment for studying Josephson junctions with magnetic systems. The virtual research environment (VRE) is designed to provide research groups with convenient tools for carrying out the entire research cycle: from building models, setting model parameters, both physical and...
With increasing performance of the heterogeneous HybriLIT platform and the release of new components, users have more modes to work with its resources. One of the key modes is the presence of a virtualized environment and interactive access to applied software.
Access to applied software can be organized using free software products, but in this case, the efficiency of resource use is...
The acquisition of experimental data is an integral part of all modern high-energy physics experiments. This task is of particular importance in the experiments of the NICA megaproject due to the high interaction rate of heavy ion collision events and the complexity of the detector systems. During experiments sessions, not only the collected data are important, but also parameters and...
One of the uppermost tasks in creating a computing system of the NICA complex is predictive modeling centers of storing and processing data from experimental setups of the complex, in particular, the BM@N detectors, and simulated events of particles collision for comparison with the expected physical result and optimization of the facility detectors geometry.
A new approach was chosen to...
Joint Institute for Nuclear Research hosts more than 40 international conferences every year. Organization means providing information about the event, registration page, abstract submission, timetable creation, and other important information. To do that, the Indico system is used heavily.
Indico is open-source software for meetings organization developed and supported by CERN. One of the...
We have introduced the Plant Disease Detection Platform (PDDP) which allows users to send photos of sick plant leaves or textual descriptions of theirappearance to obtain the information about an infection that hit the vegetation and treatment tips. The backend of the platform in terms of deep learning includes image classification model and text similarity model. The image classification...
Particle tracking is a fundamental part of the event analysis in high energy and nuclear physics (HENP). Events multiplicity increase each year along with the drastic growth of the experimental data which modern HEP detectors produce, so the classical tracking algorithms such as the well-known Kalman filter cannot satisfy speed and scaling requirements. At the same time, breakthroughs in the...
In the proces of numerical calculations, one often encounters situation, when some computationally expensive function is called multiple times for the same set of input parameters. Proper caching of alreasy obtained values can speed-up the calculations. In my work I concentrate on case, when function of multiple parameters needs to be cached. In order to be able to find requested values...
The ability to store and recall information based on associations between objects is considered a characteristic trait of intelligent systems. In biological neural networks, learning is believed to take place at a synaptic level by modification of synaptic connections. In this project, we study the statistical physics of memory and learning through the Hopfield Model of Associative Memory. We...
In this study, LIT JINR is considered as an object of implementation of corporate GIS.
This information system is designed to optimize management decisions on the operation of the
LIT building based on the creation and maintenance of an up-to-date database on all aspects of
the functioning of the building infrastructure. The main goal of the introduction of CGIS in LIT
is the competent...
