An implementation of various CPU scheduling algorithms in C++. The algorithms included are First Come First Serve (FCFS), Round Robin (RR), Shortest Process Next (SPN), Shortest Remaining Time (SRT), Highest Response Ratio Next (HRRN), Feedback (FB) and Aging. ...
In all these cases we need to maximize the CPU utilization and throughput, and to minimize the turnaround time, waiting time, and respond time. CPU Scheduling Algorithms Scheduling algorithms deal with the problems of deciding the process which is in the ready queue and need to be allocated in...
Preemptive scheduling allows a process to be interrupted in the midst of its execution, taking the CPU away and allocating it to another process. Nonpreemptive scheduling ensures that a process relinquishes control of the CPU only when it finishes with its current CPU burst. Understanding four co...
In this article, we are going to implement of Round Robin CPU Scheduling Algorithm (which is a preemptive version of FCFS algorithm) using C++ program.

Let's start looking at several vanilla scheduling algorithms. First-Come, First-Served. One ready queue, OS runs the process at head of queue, new processes come in at the end of the queue. A process does not give up CPU until it either terminates or performs IO. ...
Non-preemptive Scheduling Algorithms 非抢占式 谁先来,执行谁,执行完了再执行下一个进程。 Shortest-Job-First (SJF) 优先执行cpu执行时间最少的进程。 当一个进程结束,看当前准备队列里,哪个进程执行时间最少,执行那个。执行完毕整个进程再执行下一个。
