模拟进程调度的C语言实现

一、　　实验目的

体会UNIX 系统的进程调度方法，并通过一个简单的进程调度模拟程序的实现，加深对进程调度算法，进程切换的理解。

二、　　实验内容

采用静态优先数的方法，编写一进程调度程序模拟程序。模拟程序只对你所设置的“虚拟PCB”进行相应的调度模拟操作，即每发生“调度”时，显示出当前运行的“PCB名字”、优先数、运行时间等，而不需要对系统中真正的PCB等数据进行修改。-C　　　　UNIX　Two experimental use of static content priorities in a way, to prepare a process scheduler simulation program. Simulation program only right you have set up a "virtual PCB" accordingly scheduling simulation operation, that is, each occurrence "Dispatch" shows that the current operation "PCB name" priority number, running time, without the need for a real system, such as PCB data changes.
