CPU Scheduling Simulator

This project is a comprehensive CPU Scheduling Simulator that implements four key scheduling algorithms:

First-Come, First-Served (FCFS)Shortest Job First (SJF)Priority SchedulingRound Robin

The simulator provides a menu-based interface for easy selection and visualizes each algorithm's execution with a Gantt Chart and performance metrics like Average Waiting Time (AWT) and Average Turnaround Time (ATAT).

Features

User Input: Supports entering process details directly in the console.

Gantt Chart Visualization: Displays the process execution timeline.

Detailed Performance Metrics: Calculates AWT and ATAT for each algorithm.

Robust Error Handling: Ensures valid inputs are accepted.

How to Run the Project

Step 1: Clone the Repository :git clone https://github.com/SharadPal21/EnergyEfficientScheduler.git

cd EnergyEfficientScheduler

Step 2: Install the Required Packages : pip install matplotlib pandas numpy

Step 3: Run the Simulator python scheduler.py

Step 4: Select an Algorithm From the menu, choose: 1. First-Come, First-Served (FCFS) 2. Shortest Job First (SJF) 3. Priority Scheduling 4. Round Robin 5. Exit

Step 5: Follow the Prompts Enter process details such as:

    Arrival Time

    Burst Time

    Priority

    Power Level

Step 6: View Results

The system will display: Gantt ChartAverage Waiting Time (AWT)Average Turnaround Time (ATAT)
