Реконструкция траекторий заряженных частиц в трековых детекторах является ключевой проблемой анализа экспериментальных данных для физики высоких энергий и ядерной физики. Поток данных в современных экспериментах растет день ото дня, и традиционные методы трекинга уже не в состоянии соответствовать этим объемам данных по скорости обработки. [...]

Simulated and experimental data processing is an important issue in modern high-energy physics experiments. High interaction rate and particle multiplicity in addition to the long sequential processing time of million events are the main reasons to parallelize event processing on distributed computing systems for the NICA experiments [...]

The next phase of LHC Operations – High Luminosity LHC (HL-LHC), which is aimed at ten-fold increase in the luminosity of proton-proton collisions at the energy of 14 TeV, is expected to start operation in 2027-2028 and will deliver an unprecedented scientific data volume of multi-exabyte scale. This amount of data has to be stored and the corresponding storage system should ensure fast and reliable data delivery for processing by scientific groups distributed all over the world. [...]

A substantial data volume growth will appear with the start of the HL-LHC era. It is not well coveredby the current LHC computing model, even taking into account the hardware evolution. [...]

MPDRoot is the software framework for simulation, reconstruction and physics analysis of the simulated and experimental data for MPD experiment at NICA. It is planned to obtain ~ 108 events of heavy ion collisions for physics analysis, hence it is crucial to have the effective and efficient methodology of the systematic performance improvement of MPDRoot’s backend [...]

The amount of data produced by the scientific community is already measured in tens and hundreds ofpetabytes and will significantly grow in the future. High-throughput computing systems have provento be a solution for handling such data streams. [...]
