岳孝强:二维非定常4-Laplacian问题的多重网格规约时间并行解法器论文

本文主要研究内容

作者岳孝强,刘一寅,瞿创成(2019)在《二维非定常4-Laplacian问题的多重网格规约时间并行解法器》一文中研究指出:未来计算性能的提升依赖的是更高的并发度,而不再是更快的时钟频率,这将致使传统的时间步进算法成为数值模拟非定常问题的一个瓶颈.该文实验性地探究求解二维非定常4-Laplacian问题的具有高并发度的并行解法器,其中全离散格式为向后Euler格式和双线性矩形元,时间并行策略为通信器和进程分组下基于完全近似格式的多重网格规约时间算法.数值对比实验表明:基于F-FCF松弛、细/粗时间网格层的粗化因子为16/4的MGRIT算法具有更高的并发度,相对文献[Falgout,et al.SIAM J Sci Comput,2017,39:S298-S322]中的最优MGRIT解法器,它可提速2.4倍.
