⚡ CPU Scheduling Simulator (OS Project)

This project is a comprehensive CPU Scheduling Simulator designed to visualize and analyze the performance of various scheduling algorithms commonly studied in Operating Systems courses. It features a graphical user interface (GUI) built with tkinter, animated Gantt charts using matplotlib, and the ability to load real-time process data from the operating system using psutil.

✨ Features

• Interactive GUI: User-friendly interface built with tkinter.
• Animated Gantt Charts: Visualize the execution timeline of processes with a step-by-step animation.
• Performance Metrics: Calculate and display key performance indicators:
  • Completion Time (CT)
  • Turnaround Time (TAT)
  • Waiting Time (WT)
  • Average Turnaround Time (Avg TAT)
  • Average Waiting Time (Avg WT)
  • CPU Utilization and Throughput
• Context Switch Overhead (CSO): Algorithms can be simulated with a customizable Context Switch Overhead (CSO) time.
• Live Process Loading: Load a snapshot of currently running OS processes to use as input for the simulation, with estimated Burst Time and Priority based on CPU usage and niceness.
• Theme Switching: Toggle between Dark and Light themes.
• Export Results: Export all simulation data (input, metrics, timeline) to a CSV file.

⚙️ Supported Algorithms

The simulator includes implementations for both non-preemptive and preemptive versions of popular algorithms:

1. First-Come, First-Served (FCFS)
2. Shortest Job First (SJF) - Non-Preemptive
3. Shortest Remaining Time First (SRTF) - Preemptive (Preemptive SJF)
4. Priority - Non-Preemptive
5. Priority - Preemptive
6. Round Robin (RR) (with adjustable time quantum)

💻 Installation and Setup

Prerequisites

You must have Python installed (Python 3.x is recommended).

Install Dependencies

The required libraries are listed in requirements.txt.

1. Clone the repository:

   git clone [https://github.com/vinitkumargupta/cpu-scheduling-simulator.git](https://github.com/vinitkumargupta/cpu-scheduling-simulator.git)
   cd cpu-scheduling-simulator

2. Install the required packages:

   pip install -r requirements.txt

   Note: The psutil library is required for the "Load Live Processes" feature.

▶️ Usage

To launch the GUI, run the main script from the src directory:

python src/main_gui.py
