# 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

The following output graphs is for inputfile at (testcases/SheetQuestion.txt)

0 indicates that the cpu is free  

-1 indicates that the context switching
