OS-Scheduler

Operating systems scheduling algorithms visualization. it is an OS scheduler using different scheduling algorithms

Getting Started

These instructions will get you a copy of the project up and running on your local machine for develoment.
pip install requirements.txt
pip install tkinter
python scheduler.py

Requirements

What things you need to install ?

• matplotlib
• tkinter
• numpy

How to use?

NB - you must have an input file contains the process to be scheduled . its format is at docs/document file

1. Start the program
2. Choose an input file
3. Select the algorithm using the scrolling box .
4. Click on Show/Update Graph .

scheduler module is responsible for generating a schedule for the current processes in the system to specify the CPU usage by these processes. implemented 4 scheduling algorithms:

1. Non-Preemptive Highest Priority First.(HPF)
2. First Come First Served. (FCFS)
3. Round Robin with fixed time quantum.(RR)
4. Preemptive Shortest Remaining Time Next.(SRTN)

Library used for GUI : Tkinter
Library used for plots : matplotlib
Startup window for selecting (Input file) and (Selecting an algorithm to draw its corresponding scheduling
The following output graphs is for inputfile at (testcases/SheetQuestion.txt)

0 indicates that the cpu is free
-1 indicates that the context switching

1. First come first served

2. High priority first

3. Round Robin

4. Short remaining time next
