Аннотация
В данной работе выполнен суперкомпьютерный расчет механических напряжений в тонких пленках диоксида кремния и диоксида титана методом молекулярной динамики при различных температурах процесса напыления. Для расчета напряжений требуются атомистические кластеры больших размеров, что обусловливает необходимость использования технологий параллельных вычислений. Показано, что характер и величины напряжений существенно зависят от пленкообразующего материала, температуры подложки и энергии напыляемых атомов. Проведен анализ численной эффективности суперкомпьютерных вычислений с учетом большого размера области атомистического моделирования, а также определены способы ее повышения.
