摘　　要：本文介绍南京大学设计和实现的异构型分布式操作系统ZGL中的设备共享系统.在ZGL中,一些处理器和外部设备被定为专职的服务器.此外,任何工作站在空闲时还可以使自己临时成为计算服务器.用户可以在命令级和程序级访问设备服务器.在这两种情况下系统都将自动从可用的服务器池中选择一个服务器完成指定的任务.工作站可以作为远程控制终端与在计算服务器上执行的任务进行交互.The device sharing in the distributed operating system ZGL is described. ZGL is designed and implemented at the Nanjing University, in which some processors and peripherals are designated as dedicated servers and any idle workstations may make themselves temporally a computing server. Users can access the device server at both the command level and the program level, and in either case, the system will select a server automatically. Client workstations can act as a control terminal interacting with the task running on the remote server.
