操作系统实验2:进程调度策略的模拟实现
1、 设计一个有 N个进程共行的进程调度程序。
2、 每个进程有一个进程控制块PCB来表示,进程控制块的格式为:
进程名
优先数
到达时间
需要运行时间
已占用CPU时间
进程状态
a) 进程优先数、需要运行时间、到达时间可以事先人为地指定,也可以随机产生,注意初始化上述数值时要尽量使进程并发执行,而不是按到达时间顺序调度。
b) 进程的运行时间以时间片为单位进行计算。
c) 进程状态分为就绪、运行、完成三种状态之,分别用W、R、F表示。
3、 进程调度规则如下:
a) 就绪进程获得 CPU后都只能运行一个时间片。用已占用CPU时间加1来表示。
b) 如果运行一个时间片后,进程已占用 CPU时间达到所需要运行时间,则进程完成,撤销该进程。
c) 如果运行一个时间片后,进程已占用CPU时间还未达到所需要运行时间,即进程需要继续运行,将它插入就绪队列,队列重新排序,等待CPU。
d) 重复以上过程,直到所要进程都完成为止。

很多情况下我们需要多个线程互相协助,来完成同一个任务。但是线程很难从外部进行控制。利用线程同步技术可以使线程彼此交互,从而避免了外部控制对与时间和资源的浪费。
很多情况下我们需要多个线程互相协助,来完成同一个任务。但是线程很难从外部进行控制。利用线程同步技术可以使线程彼此交互,从而避免了外部控制对与时间和资源的浪费。-Many cases we need to assist each other to multiple threads in order to accomplish the same mission. But the thread is difficult to control from outside. The use of thread synchronization technology enables interaction between threads, thus avoiding external control with time and a waste of resources.

线程的同步
虽然多线程能给我们带来好处,但是也有不少问题需要解决。例如,对于像磁盘驱动器这样独占性系统资源,由于线程可以执行进程的任何代码段,且线程的运行是由系统调度自动完成的,具有一定的不确定性,因此就有可能出现两个线程同时对磁盘驱动器进行操作,从而出现操作错误;又例如,对于银行系统的计算机来说,可能使用一个线程来更新其用户数据库,而用另外一个线程来读取数据库以响应储户的需要,极有可能读数据库的线程读取的是未完全更新的数据库,因为可能在读的时候只有一部分数据被更新过。-thread synchronization Although multithreading can bring us benefits, but there a lso many problems to be solved. For example, as disk drives such exclusivity system resources and can thread the process of implementation of any code, and the thread running by the scheduling system automatically and to a certain extent the uncertainty, So, then there could be two threads while the disk drives operate, which have operational errors; For example, For the computer banking system, may use a thread to update users of its database, and use another thread to read a database to respond to the needs of depositors, Reading is very likely to read threads database is not fully update the database, Reading may be because the time was only part of the updated dat
