UNIX进程在PE与router间通信过程模拟中的应用

为提高Ａ－ＮＥＴ计算机的模拟速度，利用ＵＮＩＸ进程管理和进程通信的功能，编制了多进程模拟程序，若干个进程利用进程间传送信息的ｐｉｐｅ来实现同步，排斥控制由ｓｅｍａｐｈｏｒｅ来解决，使用ｐｉｐｅ，ＦＩＦＯ构成通信来实现进程间的数据交换，通信用命令的定义和数据传送过程的设定构成了通信协议。

The simulation of communication among PE and router by means of the function of UNIX process

Using the communicating mechanism between processes of UNIX,the smiulator has achieved high performance so that the behavior of message passing mechanismbetween multiple processors in A-NET machine is simulated cooperatively.The multipleprocesses perform very cooperatively through the synchronous mechanism in UNIX.Theexclusive control for shared resources is reallied through setting a public semaphore. Data transfer between processes is implemented.Using the pipe and FIFO,the communication protocal is realized through a set of input and output command which is defined inthe router simulator.
