摘要:

对流扩散方程是一类典型的偏微分方程,其并行求解方法对其他微积分方程的并行求解具有借鉴意义。对对流扩散方程的并行求解方法进行综述,分为显式直接并行、隐式迭代并行、交替分组显式并行和Monte Carlo并行四种并行求解方法,对其中涉及的计算原理进行描述,给出示例,并指出进一步研究方向。

Abstract:

The convection-diffusion equation is a typical partial differential equation. Its parallel solutions have reference significance for the parallel solutions to other equations. In this paper we conduct a survey on the parallel solutions to convection-diffusion equation. These parallel solutions are classified as four kinds of parallelism: explicit direct, implicit iterative, alternating group explicit and Monte Carlo. Computational principles and several examples are described. Finally, the prospects of future development in this field are presented.
