Description: 1、 ：编写并调试一个模拟的进程调度程序，采用“最高优先数优先”调度算法对进程进行调度。 “最高优先数优先调度算法的基本思想是把CPU分配给就绪队列中优先数最高的进程。尝试静态优先数与动态优先数两种方法：
a) 静态优先数是指优先数在整个进程运行期间不再改变。优先数可以在数据输入时指定，也可以根据到达顺序、运行时间确定。
b) 动态优先数是指进程的优先数在创建进程时可以给定一个初始值，并且可以按一定原则修改优先数。例如进程获得一次CPU后就将其优先数减少1。或者进程等待的时间超过某一时限时增加其优先数的值。
2、 编写并调试一个模拟的进程调度程序，模拟实现多级反馈队列调度算法。
3、 编写并调试一个模拟的进程调度程序，模拟实现最低松弛度优先算法。
4、 程序与报告要求：
a) 对上述要求1、2、3，至少要完成一项，鼓励尝试多种算法。
b) 输出结果要尽量详细清晰，能够反映调度后队列变化，PCB内部变化。
c) 可以选择在Windows或Linux环境下编写、运行程序
d) 鼓励使用不同的开发工具在不同平台环境上进行开发比较。
e) 在实验报告中，一方面可以对实验结果进行分析，一方面可以对各种算法进行比较，分析它们的优劣，说明各种算法适用于哪些情况下的调度。

"Highest priority priority scheduling algorithm for the basic idea is to place the CPU allocated to the priority queue highest process. Taste Examination several static and dynamic priority priority number two methods : a) static priority number is priority number in operation during the entire process will not change. priority number in the designated input data, can be reached under the order, running time determine. b) dynamic priority number refers to several priorities for the process of the creation process can be given an initial value, and according to the principle of amending certain priority number.

Description: 一、目的要求
用高级语言编写和调试一个或多个作业调度的模拟程序，以加深对作业调度算法的理解。
二、例题：为单道批处理系统设计一个作业调度程序。
由于在单道批处理系统中，作业一投入运行，它就占有计算机的一切资源直到作业完成为止，因此调度作业时不必考虑它所需要的资源是否得到满足，它所占用的 CPU时限等因素。
作业调度算法：采用先来先服务（FCFS）调度算法，即按作业提交的先后次序进行调度。总是首先调度在系统中等待时间最长的作业。
-First, the purpose of high-level language requires writing and debugging of one or more job scheduling simulation procedures in order to deepen their understanding of job scheduling algorithms. B, Example: In order to single-channel system, the design of a batch job scheduling procedures. Road as a result of a single batch system, the operation of a put into operation, it would occupy all the resources until the computer s operation has been completed, so no need to consider when scheduling operation of the resources it needs are met, it is occupied by factors such as CPU time limit. Scheduling Algorithm: The First Come First Served (FCFS) scheduling algorithm, that is, according to the order of operations submitted for scheduling. Scheduling is always first in the system waiting for the longest operations. Platform: |

PCB结构通常包括以下信息：进程名，进程优先数（或轮转时间片），进程所占用的CPU时间，进程的状态，当前队列指针等。根据调度算法的不同，PCB结构的内容可以作适当的增删。
○2 建立进程就绪队列。对两种不同算法编制入链子程序。

Description: 进程调度算法：采用最高优先数优先的调度算法（即把处理机分配给优先数最高的进程）和先来先服务算法。
每个进程有一个进程控制块（ PCB）表示。进程控制块可以包含如下信息：进程名、优先数、到达时间、需要运行时间、已用CPU时间、进程状态等等。
进程优先数及需要的运行时间可以事先人为地指定（也可以由随机数产生）。进程的到达时间为进程输入的时间。进程的运行时间以时间片为单位进行计算。
-The process of scheduling algorithms: the use of the highest priority number of priority scheduling algorithm (ie the number of processors allocated to the highest priority process) and first-come first-serve algorithm. Each process has a process control block (PCB) said. Process control block can contain the following information: process name, priority number, arrival time, the need for run-time, has spent CPU time, the process of state and so on. Process priority number and needs of the running time can be artificially designated in advance (you can also by the random number generator). Process input arrival time for the process time. The process of running time to time slice is calculated as a unit. Platform: |

Description: CPU调度算法---模拟OS所使用的所有调度算法,包括创建一个kernel,PCB,队列，调度器等。-CPU Scheduler algorithms FCFS SJF Priority
This code is a simulation of all the Scheduling algorithms an OS uses. I have tried creating a Kernel, PCB, Queue, Scheduler etc. what all an OS needs to run and execute a piece of code. Right now the code just displays the file given to in the input, If we modify the code so that it can interpret the meaning of the file then it can execute the file and can become a sub OS or VirtualMachine like JVM Platform: |
