[Documents] Job-Scheduling DL : 0: 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.

[Documents] jincheng DL : 0: 进程调度模拟程序:假设有10个进程需要在CPU上执行,分别用:先进先出调度算法基于优先数的调度算法最短执行时间调度算法确定这10个进程在CPU上的执行过程.要求每次进程调度时在屏幕上显示:当前执行进程就绪队列等待队列-Process scheduling simulation program: Suppose there are 10 process requires the CPU to perform, respectively: FIFO scheduling algorithm the number of priority-based scheduling algorithms the shortest execution time scheduling algorithm to determine the 10 process CPU on the implementation process. Requirements Every time the process of scheduling, when displayed on the screen: the current implementation process ready queue waiting queue

[Documents] 22.01 DL : 0: 编写并调试一个模拟的进程调度程序，采用“轮转法”调度算法对五个进程进行调度。　　轮转法可以是简单轮转法、可变时间片轮转法，或多队列轮转法。　　简单轮转法的基本思想是：所有就绪进程按 FCFS排成一个队列，总是把处理机分配给队首的进程，各进程占用CPU的时间片相同。如果运行进程用完它的时间片后还为完成，就把它送回到就绪队列的末尾，把处理机重新分配给队首的进程，直至所有的进程运行完毕。-Write and debug a simulation of the process scheduler, using the "Web" scheduling algorithm on the five scheduling process. Web method is a simple web method, variable time slice, or multiple queues rotation method. A simple round-robin method the basic idea is: all ready process by FCFS queue into a queue, is allocated to the processor the first team in the process, the process takes up CPU time slice of the same.If you are running the process spent its time slice for the completion, they send it back in place at the end of the queue, the processor re-allocated to the first team in the process, process until all is finished.
