One of the main method for search and exploration of oil and gas deposits and understanding the structure of the Earth’s crust is the seismic survey. The migration process allows us to estimate the position of geological boundaries under the day surface. A lot of different migration techniques were developed using the acoustic approximation. One of the obvious improvements is the transfer to...

The modern science has a class of problems related to theoretical
research, computer simulation and big data analysis.
The classical method of solution is based on usage of serial
(single threaded) algorithms having a long run time.
The modern method of solution offers high-performance parallel
(many threaded) algorithms.
They reduce the run time greatly but have specific requirements...

The problem of reliability and stability of high performance computing
parallel jobs become more and more topical with the increasing number of
cluster nodes. Existing solutions rely mainly on inefficient process of RAM
dumping to stable storage. In case of really big supercomputers, such approach –
making checkpoints - may be completely unacceptable. In this study, I examined
the model...

Встраиваемые устройства (embedded devices) становятся все более
популярными. Их можно найти в моб. телефонах, планшетах,
автомобильной электронике, роботах и т.д. Количество
задач, решаемых на таких устройствах, постоянно растет,
что приводит к необходимости объединения их в кластеры.
Такой кластер, например, установлен на сингапурском спутнике
X-Sat[xsat].

The numerical solving of systems of 2D Sine-Gordon equations is important both for pure mathematical theory and for applications. A second-order finite difference scheme is proposed for solving particular systems of 2D perturbed Sine-Gordon equations coupled via a cyclic tridiagonal matrix. The systems are considered on rectangular domains. In some cases the computational domain size and the...

An implementation of a combined evolutionary algorithm for searching of an extremum of functions with many parameters is proposed. The algorithm is designed to optimize parameters of the molecular-dynamics reactive force field potential ReaxFF. It can be efficient for a variety of extremum searching problems with arbitrary complex objective function. The algorithm itself is a hybrid of two...

Empirical many-body potentials were used to calculate the binding energies and diffusion barriers for various adatoms on the GaN (0001) surface. Potential energy surfaces were calculated for adatoms by letting them relax in c-direction on Ga terminated (0001) surface of GaN. The minimum energy positions for Ga and N adatoms on the Ga-terminated GaN (0001) surface were identified. This allowed...

The possibility of application of modern parallel computing solutions to speed up the calculations of ground states of few-body nuclei by Feynman's continual integrals method has been investigated. These calculations may require large computational time, particularly in the case of systems with many degrees of freedom. The results of application of general-purpose computing on graphics...

Partial wave analysis is a fundamental technique for extracting hadron spectra and hadron decay properties. It is employed in some current experiments like BES-III, LHCb, COMPASS, and future ones like PANDA.
The analysis is typically performed using the event-by-event maximum likelihood method. For the BES-III experiment, fitting the accumulated data (about 1.225 billion J/psi decays) using...

Significant improvement of detector resolution and, consequently, rapid growth of acquired data amounts, typical for evolving modern tomographic systems, demands development of more efficient image reconstruction software. A Medipix semiconductor detector with 55 μm spatial resolution and a cone-beam scanning scheme are used for taking projections in a microCT scanner MARS, being run at the...
