| 摘要: |
| 有效的消息通讯是提高分布存储器并行计算机性能的关键因素．点对点通讯和广播通讯是２种常用的消息通讯方法，而多播通讯（Ｍｕｌｔｉｃａｓｔｉｎｇ）是指从一个源节点同时给任意多个目标节点发送消息，这种通讯比点对点和广播２种方式更具一般性，适用于很多实际应用的需求．本文针对ＰＡＲ９５并行计算机的二维网格结构，提出一种基于网络分解的多播消息通讯方法，并比较了该方法与用多个点对点方法实现多播通讯的性能. |

| Abstract: |
| The efficient message communication is very important to improve the performance of distributed memory parallel computers. Point to point and broadcast communication are two message passing methods often used. Multicasting is to send messages from one source to any destinations, this kind of communication is more general than the two others, and required by many real world applications. A network partition based multicasting routing method for PAR95 parallel computer is provided in this paper, and the performance comparison is made. |
| Key words: Parallel processing message communication multicasting. |
