群机通信软件的实现技术

以直通式交换网络为基础，研究高速并行计算和实时仿真的通信软件。在直通网协议上直接构造消息通信原语，不用ＴＣＰ／ＩＰ协议；引入活跃消息（ａｃｔｉｖｅ ｍｅｓｓａｇｅ），支持高层通讯机制，减少通讯量和通信开销；在硬件基础上提供广播机制；为减少中断开销和通信阻塞，引入可编程控制的ＰＯＬＬＩＮＧ机制。实现了ＨＰＭＰＳ（ｈｉｇｈ ｐｅｒｆｏｒｍａｎｃｅ ｍｅｓｓａｇｅ ｐａｓｓｉｎｇ ｓｙｓｔｅｍ）。所论述

Implementation of Communication Software for Computer Cluster

According to a cut through network based on a special cross switch, a communication software for high performance parallel computing and real time simulation was studied. The following mechanisms were used in the special message passing library: a special message passing protocol which is not based on TCP/IP, an active message mechanism and a programming polling mechanism. The HPMPS(high performance message passing system) was implemented, and it can be used in high performance parallel computing and real time simulation.
