XXIV Summer School for Young Scientists and Specialists of JINR
Lipnya, July 26, 2020

Speaker: Alexander S. Ayriyan (LIT)

The HybriLIT group prepared and conducted a workshop "Introduction to the practice of parallel computing" for the participants of the XXIV Summer School for Young Scientists and Specialists (>Lipnya-2020), which was held from 24 to 26 July 2020 at a tourist shelter on Lipnja Island. Within the framework of the workshop, a brief introduction to the practice of parallel computing on distributed and shared memory systems was given, such parallel computing technologies as Message Passing Interface (MPI), Open Multi-Processing (OpenMP), Compute Unified Device Architecture (CUDA), Open Computing Language (OpenCL). The workshop was conducted on a portable autonomous computing system with the working title Portable HybriLIT, which fully simulates the work at the HybriLIT Training and Testing Ground at the user interface level. The workshop also aimed to test this system in the conditions of real practical training.

The DIRAC Interware platform enables the integration of distributed heterogeneous computing resources and storage systems into a unified system. Since 2009, it has been developed as a versatile open-source tool. At present, the DIRAC-based unified environment, which includes both computing resources and data storage systems, is used to generate and reconstruct events of the MPD experiment, to study the SARS-CoV-2 virus within the Folding@Home project on available cloud resources and to integrate clouds of the JINR Member States’ organizations into a distributed platform.

Development of a service for conducting radiobiological studies on the HybriLIT platform.

The report covers the development of the server part of an information system for analyzing behavioral and pathomorphological changes in the central nervous system in the study of the effects of ionizing radiation and other factors on biological objects. For data acquisition and storage, a client-server architecture of the application was elaborated and a database was designed. The given system provides a wide range of opportunities for users and takes into account the specifics of working with biological data. The system was built on the basis of the HybriLIT heterogeneous platform.

Algorithms of computer vision for the analysis of behavioral responses of small laboratory animals.

Joint LIT-LRB workshop
June 18, 2020

The report considers the possibility of automating the evaluation of behavioral parameters of laboratory animals during the experiment using computer vision algorithms when analyzing the video recordings of the experiment. Specific algorithms that allow one to evaluate the track of a laboratory animal, as well as algorithms that automate the reading of the parameters of the experiment, such as the marking of the laboratory pool and the coordinates of the test site, are presented.
