群机是一组相互连接的计算机，每台机器既能够独立地运行，又能够透明地访问其它计算机的资源，使用户感觉象使用一台计算机一样．本文提供一个分布式进程间通讯系统，把基于消息操作系统的本地ＩＰＣ语义透明地扩展到网络上，网络通讯协议采用 ｘｋｅｒｎｅｌ技术实现，群机间的进程能够用本地ＩＰＣ界面进行通讯，透明地访问远程计算机资源 Group of machines is a group of interconnected computers, each machine can run independently, but also transparent access to other computer resources, so that users feel like using a computer. This article provides a distributed interprocess communication system, which extends the semantics of the local IPC based on the message operating system transparently to the network. The network communication protocol is implemented using xkernel technology. The process between the groups of machines can communicate with the local IPC interface, Access to remote computer resources
