Storage_Simulator0001
在采用多道程序设计的系统中,往往有若干个进程同时处于就绪状态。当就绪进程个数大于处理机数时,就必须依照某种策略来决定哪些进程优先占用处理机。本实验模拟在单处理机情况下的处理机调度,帮助学生加深了解处理机调度的工作。
二、实验类型
设计型。
三、预习内容
预习课本处理机调度有关内容,包括进程占用处理机的策略方法。
四、实验要求与提示
设计进程调度算法,进程数不定;包含几种调度算法,并加以实现;输出进程的调度过程——进程的状态、链表等。要求使用优先权法和轮转法模拟进程调度过程。
【提示】:简化假设
1) 进程为计算型的(无I/O)
2) 进程状态:ready、running、finish
3) 进程需要的CPU时间以时间片为单位确定
【提示】:算法描述
1) 优先权法——动态优先权,当前运行进程用完时间片后,其优先权减去一个常数。
2) 轮转法
