Scientists Model Turbulence at Atomic Level
Scientists at HSE University and MIPT have developed a supercomputer-based method to model fluid flows at atomistic scales making it possible to describe the emergence of turbulence. The researchers used the supercomputers cHARISMa and Desmos to compute the flow of a fluid consisting of several hundred million atoms. This method is already being used to simulate the flow of liquid-metal lead coolant in a nuclear reactor. The paper has been published in The International Journal of High Performance Computing Applications.
HSE cHARISMa Supercomputer Completes One Million Tasks
Since 2019, the cHARISMa supercomputer has been helping staff, teachers and students of HSE university to solve research tasks. In February 2023, it completed its millionth task—a computational experiment dedicated to studying the phenomenon of multiparticle localisation in quasi-one-dimensional quantum systems.
From Covid-19 to Risk Appetite: How HSE University’s Supercomputer Helps Researchers
Whether researching how the human brain works, identifying the source of COVID-19, running complex calculations or testing scientific hypotheses, supercomputers can help us solve the most complex tasks. One of the most powerful supercomputers in the CIS is cHARISMa, which is now in its third year of operation at HSE University. Pavel Kostenetskiy, Head of the HSE University Supercomputer Modeling Unit, talks about how the supercomputer works and what kind of projects it works on.
HSE Supercomputer Doubles Its Performance
The peak performance of the HSE cHARISMa supercomputer has doubled, reaching 2 petaflops (2 quadrillion floating-point operations per second). HSE University now outperforms the Kurchatov Institute in terms of computing power. The only more powerful university computers are MSU’s Lomonosov-2 and SPbPU’s Polytechnic. Thanks to the timely upgrade, cHARISMa has retained its respectable 6th position among the Top 50 most powerful computer systems in the CIS for three years.
Open-Source GPU Technology for Supercomputers: Researchers Navigate Advantages and Disadvantages
Researchers from the HSE International Laboratory for Supercomputer Atomistic Modelling and Multi-scale Analysis, JIHT RAS and MIPT have compared the performance of popular molecular modelling programs on GPU accelerators produced by AMD and Nvidia. In apaper published by the International Journal of High Performance Computing Applications, the scholars ported LAMMPS on the new open-source GPU technology, AMD HIP, for the first time.
HSE Supercomputer Is Named cHARISMa
In July this year, there was an open vote to name the HSE’s supercomputer. Two names - Corvus (‘crow’ in Latin; the crow is HSE's mascot) and cHARISMa (Computer of HSE for Artificial Intelligence and Supercomputer Modelling) – received the most votes. The latter won by a narrow margin, with 441 people (one in three of those who took part in the vote) choosing this name.
Supercomputer Set Up at HSE University
A new supercomputer, which has been recently set up at MIEM, will allow the university to carry out high quality research in deep learning and mathematical modeling. The computer was ranked sixth in the April Top-50 ranking of supercomputers in Russia.
