Abstract

This paper investigates the effectiveness of the DVM/DVMH technology as applied to the parallel solution of parametric problems in gas dynamics. The solution of these problems is based on the construction of a generalized computational experiment, which involves multiple solutions of the problem with the variation of its key parameters. This approach is efficient only when using parallel technologies, which make it possible to organize the concurrent solution of the problem with various input data in multitasking mode. We conducted a series of numerical experiments to solve one-dimensional and two-dimensional parametric problems of gas dynamics by varying the number of computational nodes, their parameters, and graphics coprocessors connected. The computational results for these test problems in the form of efficiency and speedup estimates are presented.

使用DVM / DVMH技术的气体动力学参数问题的并行解决方案

摘要

本文研究了DVM / DVMH技术应用于并行解决气体动力学参数问题的有效性。这些问题的解决方案基于通用计算实验的构建，该实验涉及关键参数变化的问题的多种解决方案。这种方法仅在使用并行技术时才有效，这使得可以在多任务模式下使用各种输入数据来组织问题的并发解决方案。我们进行了一系列数值实验，通过改变计算节点的数量，其参数和连接的图形协处理器来解决一维和二维气体动力学的参数问题。
