CPU Scheduler Simulator

An application to simulate few CPU scheduling Policies.

---

Overview

One of the main tasks of an operating system is scheduling processes to run on the CPU. The goal of this programming project is to implement a simulator with different scheduling algorithms. The simulator should select a process to run from the ready queue based on the scheduling algorithm chosen at runtime. (It does not require any actual process creation or execution.)

Algorithms

• First Come First Serve CPU Scheduling Algorithm
• Shortest Job First CPU Scheduling Algorithm
• Shortest Remaining Time First CPU Scheduling Algorithm
• Round Robin CPU Scheduling Algorithm

Features

• Creation of Process table (Inputing Details of Process)
• Performing Algorithm (fcfsm,sjf,srtf,round robin)
• Computes Completion time, Waiting time, Response time and Turn Around Time for Every Process
• Computes Average Response time, Averge Waiting time and Average Turn Around Time for all Algorithms.
• Print Gantt Chart

Header Files

process

fcfs

header file storing attributes related to fcfs and functions to perform fcfs All the required information of other attributes/ functions are explained in comments in code file itself.

sjf

header file storing attributes related to fcfs and functions to perform sjf All the required information of other attributes/ functions are explained in comments in code file itself.
