进程调度
进程调度算法有FIFO,优先数调度算法,时间片轮转调度算法,分级调度算法,目前主要是考FIFO和优先数调度算法(静态优先级)。
输入:进程流文件,其中存储的是一系列要执行的进程,
每个作业包括四个数据项:
进程名 进程状态(1就绪 2等待 3运行) 所需时间 优先数(0级最高)
输出:
进程执行流 和等待时间 平均等待时间
本程序包括:FIFO,优先数调度算法,时间片轮转调度算法

熟悉操作系统的几种作业调度算法,包括FCFS,SJB以及小作业优先的几种算法,并能够对其进行编程实现。
在后备作业队列中输入5个作业各自运行所需要的时间及存储空间。
(1) 按先来先服务的原则进行调度,输出作业调度的顺序及等待的时间和。
(2) 按最短作业(即运行时间最短)优先的原则进行调度,输出作业调度的顺序及等待时间和。
(3) 按最小作业(即存储空间最小)优先的原则进行调度,输出作业调度的顺序及等待的时间和。
