Description
RU-Protvino-IHEP site is the one of three biggest WLCG Tier-2 centers in Russia. The computing infrastructure serves for "big four" LHC high energy physics experiments such as Atlas, Alice, CMS, LHCb and local experiments at IHEP such as OKA, BEC, radio biology stands and others. In this work the current status of the computing capacities, networking and engineering infrastructure is shown as...
Current status of the INP BSU grid site. An overview of INP BSU computational facilities usage and cloud resources integration with JINR cloud is presented.

Abstract
Growing needs for computational resources, data storage within higher-educational institutions and the requirement for a lot of investment and financial resources the idea or the concept of “National Research Cloud Platform (NRCP)” is crucial to provide necessary IT support for educational, research and development activities,...
Since 2019, the COMPASS experiment works on the Frontera high performance computer. This is a large machine (number 5 in the ranking of the most powerful supercomputers in 2019) and details, problems, and approaches to organizing data processing on this machine are presented in this report.
ParaSCIP is one of the few open-source solvers implementing a parallel version of the Branch-and-Bound (BNB) algorithm for discrete and global optimization problems adapted for computing systems with distributed memory, e.g. for clusters and supercomputers. As is known from publications there were successful using up to 80,000 CPU cores during solving problems from the MIPLIB test libraries....
Развитие технологий искусственного интеллекта и больших данных (big data) явилось стимулом разработки новых инструментальных средств организации и автоматизации рабочих процессов (workflow). Проект Jupyter – один из основных проектов автоматизации рабочих процессов в области искусственного интеллекта. Ключевыми парадигмами проекта являются клиент-серверная модель и графическая интерактивная...
Contemporary computing systems are commonly characterized in terms of data-intensive workflows, that are managed by utilizing large number of heterogeneous computing and storage elements interconnected through complex communication topologies. As the scale of the system grows and workloads become more heterogeneous in both inner structure and the arrival patterns, scheduling problem becomes...
The JINR distributed information and computing environment (DICE) was created to join resources for solving common scientific tasks as well as to distribute a peak loads across resources of partner organizations from JINR Member States. To monitor hardware resources and services of growing DICE infrastructure a system based on Prometheus and Thanos was designed and deployed. Collected metrics...
The amount of data produced by a scientific community already measured tens and hundreds of petadytes and will significantly grow in future. Distributed computing systems have proven to be an effective solution for handling such data streams. Technologies and a set of products that allow deployment and use of important components of a distributed system already existed, quite stable and...
The topic of the presented report is various approaches to modeling the process of solving optimization problems using the desktopgrid [1]. The report summarizes the practical experience of performing computations on local infrastructures and on voluntary computing projects. The creation of preliminary models of the computational process will allow to avoid many systemic complexities in the...
AQMS - in this case, the broad name includes in particular measurement and mathematical modeling of air pollution, geoinformation technologies for the analysis of their results and preparation and implementation of modeling on parallel supercomputer clusters. In the past few years, my team and I have been researching and refining mathematical models, expanding the amount of processed input...
In this work consider a distributed computing system in which the control functions are dispersed in several dominant nodes that are directly connected to all the others. This configuration reduces the vulnerability of the entire network, since the failure of a single control element immediately disrupts its operation. On the other hand, the large length of the maximum shortest chain...
As a bug tracking and project management system, the ALICE experiment uses Jira software, which provides a wide range of configuration options. Jira also allows to significantly expand the basic functionality with custom plugins. In this work, the LinkedIssuesHasStatus plugin for the JIRA service of the ALICE experiment is developed and implemented. Plugin returns tickets that have linked...
We are developing a tool for for calling functions between different environments. And by "different environment" we mean both, different programming languages and different machines. This tool is a remote procedure call protocol(and it's implementation), that is optimized for simplicity and can support higher-order functions. In our implementation, functions are never serialized and are...
В последние годы все большее распространение получают интеллектуальные системы видеообзора: охранные системы, системы анализа дорожной обстановки, системы выявления девиантного поведения, непрерывно растет число видеокамер, увеличивается разрешение получаемых изображений, усложняются алгоритмы обработки. Все это приводит к непрерывному увеличению генерируемой информации, и соответствующее...
Распределённые вычисления сегодня достаточно востребованы в задачах пакетной обработки данных, но текущие решения, которые позволяют в Python их использовать, либо слишком узкоспециализированные, либо не дают полной отказоустойчивости.
В рамках выпускной квалификационной работы был разработан высокоуровневый интерфейс на Python (далее SBN-Python) к новому С++ фреймворку Subordination,...
Предлагаются рациональные инструменты для инновационного развития и совершенствования способов оценки качества технических систем на этапе эксплуатации. Инновации основаны на том, что предлагаются для применения совокупность взаимосвязанных моделей, методик и реализующих их программ для ЭВМ, которые позволят сократить затраты времени и ресурсов на оценку качества систем и (или) элементов...
