GREEN SUPERCOMPUTING - CALCULATING TSUNAMI WAVE PROPAGATION

(STEF92 Technology, 2024-12-15, Mikhail Lavrentiev, Konstantin Lysakov, Andrey Marchuk, Konstantin Oblaukhov)

Nowadays, the use of supercomputing for solving almost any task ranging from industrial to the ecological ones has been increasing. It should be noted that this requires lots of energy, which negatively affects the environment and is costly. However, in a number of cases it is possible to achieve high performance calculations without the use of supercomputers but instead by relying on special processors, focused on a particular class of tasks. While optimizing the computational pipeline for a particular mathematic...

NUMERICAL SIMULATION OF THE PECVD REACTOR FOR THE SOLAR CELLS AND THE GREEN ENERGY

(STEF92 Technology, 2020-12-20, Mikhail Lavrentiev, Alexey Snytnikov)

Show more

One of the possible ways of transition to the eco-friendly energy is widening the use of the solar cells. It requires the enhancement of their efficiency and the reduction of the cost of manufacture. One of the most common tools for producing silicon films for the solar cells is the Plasma Enhanced Chemical Vapor Deposition (PECVD). The present paper describes a new Particle-In-Cell code for simulation of the PECVD reactor. The goal of the research is the optimization of real PECVD reactor by means of the simulati...

MODERN HARDWARE FACILITIES TO ACCELERATE SEISMIC DATA PROCESSING

(STEF92 Technology, 2018-11-20, Mikhail Lavrentiev)

Show more

Geophysical exploration, the necessary part of oil and gas exploration, generates more and more data, subject of processing. The most powerful super computer clusters are used by business and academic institutions. However, often it is necessary to have evaluation of the measured data shortly after measurements, even in the field. Modern computer architectures, namely Graphic Processing Units (GPUs) and Field Programmable Gates Arrays (FPGAs) provide a good basis for PC-based fast data processing, to have, say, su...
