PIConGPU on Desmos Supercomputer: GPU Acceleration, Scalability and Storage Bottleneck
P. 290–302.
Particle-in-Cell models are among the most demanding computational problems that require appropriate supercomputing hardware. In this paper we consider the solution of generic PIC problems on the Desmos supercomputer equipped with novel AMD MI50 GPUs and Angara interconnect. The open-source PIConGPU code is used. The acceleration limits and bottlenecks for this type of calculations are considered.

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 ...

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 ...

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 ...

Большинство проблем структурной вычислительной биологии требуют решения задачи минимизации энергетической функции (силового поля), определенной на геометрии молекулы. Это позволяет определять свойства молекул, предсказывать правильное положение белковых цепей, находить лучшую состыковку молекул при предсказании комплексообразования (докинге), проверять гипотезы относительно белкового дизайна и решать многие другие задачи, возникающие при современной разработке лекарственных средств. В случае низкомолекулярных соединений ...

Nowadays, remotely sensed images are used for various purposes in different applications. One of them is the cadastral application using high resolution satellite imagery. The edge detection has an important role in image processing, especially in the detection and the extraction physical features, those which are useful to their enforcement in the analysis of cadasters. ...

A timing attack against an AES-type block cipher CUDA implementa- tion is presented. Our experiments show that it is possible to extract a secret AES 128-bit key with complexity of 2^32 chosen plaintext encryptions. This approach may be applied to AES with other key sizes and, moreover, to any block cipher with a linear transform that is ...

The population annealing algorithm is a novel approach to study systems with rough free-energy landscapes, such as spin glasses. It combines the power of simulated annealing, Boltzmann weighted differential reproduction and sequential Monte Carlo process to bring the population of replicas to the equilibrium even in the low-temperature region. Moreover, it provides a very good ...

In this paper we consider the efficiency of hybrid systemson-a-chip for high-performance calculations. Firstly, we build Roofline performance models for the systems considered using Empirical Roofline Toolkit and compare the results with the theoretical estimates. Secondly, we use LAMMPS as an example of the molecular dynamic package to demonstrate its performance and efficiency in various ...

Low-cost gaze tracking systems are in great demand due to their wide range of application. Commonly, extra devices are needed (for instance, head mounted cameras); however, in this investigation gaze tracking is performed in real-time based on the video stream from an infrared video camera. A comparative analysis of the existing analogues was executed and ...
