Performance of Elbrus Processors for Computational Materials Science Codes and Fast Fourier Transform
P. 92–103.
Modern Elbrus-4S and Elbrus-8S processors provide a level of floating-point performance close to that of widespread x86_64 CPUs that are predominantly used in high-performance computing (HPC). The uniqueness of the software ecosystem of Elbrus processors requires special attention in the case of their deployment for execution of mainstream computational codes. In this paper, we consider the performance of one widely used code for computational materials science (VASP), as well as FFT libraries. The results for the Elbrus processors are embedded into the context of performance of modern x86_64 CPUs.

This article presents a research on Hexagonal Boron Nitride (h-BN) monolayer cell strain effect 2 % and 4 %. Structure of h-BN with nitrogen vacancy, with boron vacancy and with divacancy was considered for this. The calculations were carried out within framework of the density functional formalism with gradient corrections and using the VASP package. ...

The article introduces the theoretical foundations of the modern method of storing, transmitting and processing signals: digital processing. It’s a way to use relatively small number of values instead of continuous real signal.
For example, when transmitting information in telephony, speech is concentrated in the bandwidth up to 4 kHz. But we need doubled frequency 8 ...

This chapter presents the algorithm for estimating spectral correlation
function of a random process that is a valid bi-frequency description of the probabilistic
properties of any wide-sense cyclostationary process and relates to its cyclic
autocorrelation function via Fourier transform. The key point of the algorithm is that
it is based on the two-dimensional discrete Fourier transform of the sample ...

Nowadays, the wide spectrum of Intel Xeon processors is available. The new Zen CPU architecture developed by AMD has extended the number of options for x86_64 HPC hardware. This large number of options makes the optimal CPU choice for HPC systems not a straightforward procedure. Such a co-design procedure should follow the requests from the ...

This paper presents an improved incremental self-organizing map (I2SOM) network that uses automatic threshold (AT) value for the segmentation of ultrasound (US) images. In order to show the validity of proposed scheme, it has been compared with Kohonen’s SOM. Two-dimensional (2D) fast Fourier transform (FFT) and 2D continuous wavelet transform (CWT) were computed in order ...
