Повышение производительности программного комплекса для моделирования внутренних гравитационных волн IGW Research с помощью Intel® Parallel Studio XE 2013
The new version of the program complex intended for numerical modeling of propagation and transformation of internal gravity waves in the ocean, with a finalized unit calculation of a ray of internal waves and with a paralleling of the program, which can significantly speed up the ongoing computation is presented. As a practical example of the proposed study addictive properties of the shelf of the Baltic Sea from the point of view of long internal waves on the basis of the ray approach is offered. The values of the coefficient of capture are calculated and the corresponding maps are constructed.
In this paper software package for numerical modeling of transformation and propagation of internal gravity waves (IGW) in the World Ocean is presented. Short overview of implemented numerical models is given. They are: extended nonlinear evolutionary equation of Korteveg-de-Vries type with combined nonlinearity with variable coefficients (Gardner equation) and ray model reproducing the effect of refraction in an IGW package. The developed software package is unique and topical for this class of geophysical applications. Description of user interface and main working modes of the software are presented.
One of the most important problems, by development of the automated systems of scientific researches is providing efficient performance of computers. The algorithm for tasks division among the processors of molecular-dynamic sub-systems modeling of the research-informational system Slag Melt system is described. The authors recommend the method of optimizing the algorithm as well as an estimation and calculation of the system efficiency and improving its operation.
The article is devoted to inclusion of the topic "parallel computing" in the school informatics . Some methodical materials prepared in the course of work on the "Permian version" of a propaedeutic course of computer science (the author team is M.A. Plaksin, N.I. Ivanova, O.L. Rusakova) are described.

The physical-mathematical model of the sensors block of space radiation fluxes parameters monitoring module has been developed. The simulation of the sensors block output has been carried out using the series of the spectra representing space radiation spectra at different spaceship orbits in different phases of the solar activity cycle. The optimisation of the sensors block of space radiation fluxes parameters monitoring module has been carried out based on the simulation results.
Now we have the need for methodics of teaching the topic "parallel computing" in secondary school. The paper presents a three-year experience of the author in this field: a methodical approach, the selection of materials, the business games, experience of tasks on parallel computing at the contest "TRIZformashka", classes of tasks, examples of tasks, program executors, texts for propaedeutic textbook on informatics.
This book constitutes the refereed post-conference proceedings of the 5th Russian Supercomputing Days, RuSCDays 2019, held in Moscow, Russia, in September 2019.
The 60 revised full papers presented were carefully reviewed and selected from 127 submissions.
A method based on the spectral analysis of thermowave oscillations formed under the effect of radiation of lasers operated in a periodic pulsed mode is developed for investigating the state of the interface of multilayered systems. The method is based on high sensitivity of the shape of the oscillating component of the pyrometric signal to adhesion characteristics of the phase interface. The shape of the signal is quantitatively estimated using the correlation coefficient (for a film–interface system) and the transfer function (for multilayered specimens).
Let G be a semisimple algebraic group whose decomposition into the product of simple components does not contain simple groups of type A, and P⊆G be a parabolic subgroup. Extending the results of Popov , we enumerate all triples (G, P, n) such that (a) there exists an open G-orbit on the multiple flag variety G/P × G/P × . . . × G/P (n factors), (b) the number of G-orbits on the multiple flag variety is finite.
