摘要
针对一维抛物方程的初边值问题,在分组显式(GE)并行解法的基础之上,利用冗余计算来遮盖部分通信的重叠边界优化技术,结合曙光-2000并行计算机系统,得到了一个通信时间缩短、并行效率提高的分布式并行算法。
In this paper, we provide a new parallel algorithm for one-dimensional parabolic equation for distributed memory system. We obtain a distributed parallel algorithm with shorted time and high efficiency and by making use of the technology of over-lapped boundary optimization which covers parts of communication by taking advantage of redundant computation, combining with Dawning-2000 parallel computer system.
