Network Parallel Computing Approach of Hydromechanical Problem on Rectangle Domain Using Line-Relaxation Method

提出了一个用线松弛法解决长矩形区域流场问题的网络并行方案 ,详细讨论了使用虚拟节点处理第 2类边值条件的多重网格技术和斑马线松弛多重网格技术的并行化方法 ,给出了从计算方法到它的并行化的完整过程 .此方案与传统的求解方案相比 ,有较好的收敛速度 ,并减少了通讯 ,在网络并行环境中取得了较高的加速比 .

This paper proposes a network parallel computing approach for hydromechanical problem on rectangle domain using line relaxation method.A multigrid method with virtual nodes for the second kind boundary condition and a parallel scheme of zebra line relaxation multigrid technique are discussed.This approach has a better converge rate and less communication,commparing with traditional approaches;it can achieve a high speed up on network parallel environment.
