Description
Развитие экспериментов в различных областях приводит к увеличению объёма хранения и интенсивности обработки данных. Этот факт приводит к повышению количественных и качественных требований к системам хранения данных. Рассматриваются текущий статус, результаты проведённой в последнее время модернизации и перспективы дальнейшего развития работизированного хранилища данных Многофункционального...
NetIs is a service used to monitor the Data Acquisition network of the ATLAS experiment. The first version was developed at CERN in 2010. The network group would like to replace NetIs because it is difficult to maintain and store data in a Round Robin Database (RRD), resulting in a loss of granularity over time that makes the tool unsuitable for retrieving accurate values from the past. The...
The Russian Scientific Data Lake is a part of Data Lake R&D conducted by the DOMA project. It aims to mitigate the present LHC computing model drawbacks to cope with an unprecedented scientific data volume at the multi-exabyte scale that will be delivered by experiments in the High Luminosity phase of the LHC. The prototype of the Russian Scientific Data Lake is being implemented and it tests...
The problem of evaluating the efficiency of the JINR MLIT grid sites has always been topical. At the beginning of 2021, a new accounting system was created, it managed to fully cover the functionality of the previous system and further expand it. The report will provide detailed information on the implemented accounting system.

One of the uppermost tasks in creating a computing system of the NICA complex is to model centers of storing and processing data that come from experimental setups of the complex, in particular, the BM@N detector, or are generated using special software for checking of the developed data processing algorithms and for comparison with the expected physical result.
After reviewing the existing...
The concept of a "virtual testbed", namely the creation of problem-oriented environment for full-featured modeling for the investigated phenomenon or behavior of a complex technical object,
has now acquired a finished look. The design of this concept contributed to the development of complex mathematical models suitable for full-fledged computational experiments and improvement of a computer...
The modern computing center is not only a production capacity, it is also a stable work. Stability means not only software, the reliability of the software component. It is also assembly components. It is important to ensure this before the production. One of the ways is testing components for performance, reliability, assembly defects. In this work we will present the methodology for...
Modeling network data traffic is the most important task in the design and construction of new network centers and campus networks. The results of the analysis of models can be applied in the reorganization of existing centers and in the configuration of data routing protocols based on the use of links. The paper shows how constant monitoring of the main directions of data transfer allows...
Computing Center of the Institute for High Energy Physics in Protvino provides computing and storage resources for various HEP experiments (Atlas, CMS, Alice, LHCb) and currently operates more than 150 working nodes with around 3000 cores and provides near 2PB of disk space. All resources are connected through two 10Gb/s links to LHCONE and other research networks. IHEP computing center has...
This report will present services for performing computational neurobiology tasks for working with experimental data from nuclear magnetic resonance imaging of the human brain. These Services are created as separate modules based on the "Digital Laboratory platform" NRC "Kurchatov Institute".
On the basis of the distributed modular platform «Digital Laboratory» at NRC "Kurchatov Institute"...
In this work, we present a formal mathematical model and software library for modelling hardware components and software systems based on the SOPN Petri network and CSharp programming language.
A discrete stochastic model denoted as SOPN, is presented, which combines the qualities of coloured, hierarchical and generalized Petri nets. The model is a series of extensions over the necessary...
Large-scale computing centers supporting modern scientific experiments store and analyze vast amounts of data. A noticeable number of computing jobs executed within the complex distributed computing environments ends with errors of some kind, and the amount of error log data generated every day complicates manual analysis by human experts. Moreover, traditional methods such as specifying...
