P. 276–289.
Kolotinskii D., Alexei Timofeev
According to the TOP-500 supercomputer ranking [27], since 2017, the share of supercomputers which have NVIDIA V100 and A100 graphics accelerators has been continuously growing, reaching 80% by November 2021 from the total number of supercomputers with accelerators and co-processors. This paper presents the results of an assessment of energy and economic efficiency, as well as the performance study of using V100 and A100 graphics accelerators in the framework of complex plasma physics. In addition, the use of several accelerators for one calculation is considered. In order to quantify the effectiveness of the considered devices, we use the following metrics: calculation time, resource efficiency, economical efficiency, power efficiency.

This work presents atomic-scale modeling of the perturbed flow of a Lennard-Jones fluid in a quasi-two-dimensional system containing one billion atoms. A statistically stationary flow regime corresponding to a Reynolds number of Re ≈ 1000 has been achieved, the flow structure has been analyzed, and the energy spectrum of velocities has been calculated. The results ...

Accurate benchmarking is critical for selecting computing architectures optimized for machine learning (ML) tasks. Conventional benchmarks such as High-Performance Linpack (HPL) and High Performance Conjugate Gradients (HPCG) often fail to capture the diversity and complexity of modern ML workloads. This study investigates the correlation between hardware parameters (e.g., processor architecture, cache size, frequency) and ML ...

The detection of computational tasks that inefficiently utilize high-performance computing (HPC) resources is one of the major problems facing supercomputer centers. Such tasks can block valuable computational resources and slow down other supercomputer users’ computations. HPC TaskMaster, a task-performance monitoring system developed at the Higher School of Economics, addresses this issue by analyzing task metrics, ...

Handling vast amounts of data is crucial in today's world. The growth of high-performance computing has created a need for parallelization, particularly in the area of machine learning algorithms such as ANN (Approximate Nearest Neighbors). To improve the speed of these algorithms, it is important to optimize them for specific processor architectures. RISC-V (Reduced Instruction ...

Modern storage systems intensively utilize data prefetching algorithms while processing sequencesof the read requests. Performance of the prefetching algorithm (for instance increase of the cache hitratio of the cache system – CHR) directly affects overall performance characteristics of the storagesystem (read latency, IOPS, etc.).There are widely known prefetching algorithms that are focused on the discovery ...

Исследуются динамические свойства системы из конечного числа одноименно заряженных частиц, взаимодействующих по экранированному кулоновскому потенциалу в поле параболической ловушки. Методом анализа нормальных мод в квазигармоническом приближении получено пространственное распределение амплитуд колебаний частиц в системе: высокочастотные колебания локализуются в ее центральной области. Это приводит к тому, что в разных областях структуры спектры колебаний частиц различны. Для ...

We study the spatial distribution of dynamical properties in a strongly coupled confined experimental dust monolayer with a dense central region and a rarefied periphery. We show that the dust particle oscillations spectrum shifts into the low-frequency range from the center of the structure toward its periphery. Correspondingly, the high-frequency particle oscillations are localized in ...

Fluid dynamics is a ubiquitous problem that arises in different branches of science and industry. It is usually tackled by numerically solving differential equations on a finite grid. Molecular dynamics was not a feasible tool to approach fluid dynamics until very recently due to its disproportional computational complexity. In this paper we propose a new ...

A complex (dusty) plasma system is well known as a paradigmatic model for studying the kinetics of solid-liquid phase transitions in inactive condensed matter. At the same time, under certain conditions a complex plasma system can also display characteristics of an active medium with the micron-sized particles converting energy of the ambient environment into motility ...
