本注释的目的是提出允许并行实现的偏微分演化方程的时间离散化。该方法基于艺术欧拉方案,本着与标准空间近似相同的精神,在时间上结合了粗分辨率和独立的精细分辨率。由此产生的并行实现是在非标准时间方向上完成的。其主要目标涉及实时问题,因此提出了“parareal”算法的术语。 (C) 2001 年科学院/Elsevier SAS 科学与医学版。
The purpose of this Note is to propose a time discretization of a partial differential evolution equation that allows for parallel implementations. The method, based on art Euler scheme, combines coarse resolutions and independent fine resolutions in time in the same spirit as standard spacial approximations. The resulting parallel implementation is done in the non standard time direction. Its main goal concerns real time problems, hence the proposed terminology of "parareal" algorithm.
