Кольца, состоящие из различного числа атомов, являются основным структурным элементом во многих неупорядоченных веществах. В настоящей статье представлен параллельный алгоритм получения приближенной функции распределения колец по числу атомов, основанный на методе Монте-Карло. Алгоритм применен к кластерам диоксида кремния, содержащим до миллиона атомов. Исследована эффективность алгоритма, как функция числа используемых вычислительных ядер, вплоть до 1024. The rings consisting of various number of atoms are basic structural elements in many disordered solids. In this paper, a parallel algorithm for calculating an approximate ring distribution function by the number of atoms is proposed. The algorithm is based on the Monte Carlo method and is applied to SiO$_2$ clusters consisting of up to $10^6$ atoms. The efficiency of the algorithm is studied using up to 1024 computational cores.

The Monte Carlo Method

The impurity breakdown was simulated in numerical calculations. The distribution function for an electron in the electric field was calculated using the Monte-Carlo method. The electron concentration in the impurity ground state and in the first subband was determined by solving the rate equations. It was found out that a population inversion between the 1s-level and the bottom of the first subband is likely to arise. The requirements for the population inversion to occur were determined.

The Monte Carlo Method

The article has considered the calculation of the unified glare rating (UGR) based on the luminance spatial-angular distribution (LSAD). The method of local estimations of the Monte Carlo method is proposed as a method for modeling LSAD. On the basis of LSAD, it becomes possible to evaluate the quality of lighting by many criteria, including the generally accepted UGR. UGR allows preliminary assessment of the level of comfort for performing a visual task in a lighting system. A new method of "pixel-by-pixel" calculation of UGR based on LSAD is proposed.

The article is a continuation of the software research to perform probabilistic seismic hazard analysis (PSHA) as one of the main stages in engineering seismic surveys. The article provides an overview of modern software for PSHA based on the Monte Carlo method, describes in detail the work of foreign programs OpenQuake Engine and EqHaz. A test calculation of seismic hazard was carried out to compare the functionality of domestic and foreign software.
