分布式并行处理中的异步通信技术及其分析

在基于网络环境的分布式并行计算中,因为一般情况下,局域网的底层通信协议多为以太网协议,而以太网采用的是总线通信和信道竞争两种技术,因此基于网络环境的分布式并行计算中最大的问题可能就是要解决好通信开销的问题。根据以太网的特性,提出了一种子任务计算和通信错开的解决方案,并已成功用于求解一个经典的流体力学问题,取得了良好的效果。该文着从理论上分析该方案的加速比和并行效率等。

An Asynchronous Distributed Parallel Arithmetic and Its Analysis

Generally speaking,in the lower layer of local network,the protocol is Ethernet,and Ethernet is base d on bus topology and Channel Competition.So the most important problem for distributed parallel computing,may be too larger for communication spending.In this paper,we present a scheme to solve this problem,and give the annalysis of their parallel efficiency and accelerate proportion.
