CPU Scheduling Algorithms

This repository contains two main components:

1. CPU Scheduling Algorithms: Core implementations of CPU scheduling algorithms (without UI).
2. CPU Scheduling App with UI: An interactive application for visualizing and running CPU scheduling algorithms, combining both the algorithms and a graphical user interface (GUI).

Features

• Supported Algorithms:
  • First-Come First-Served (FCFS)
  • Shortest Job First (SJF)
  • Shortest Remaining Time First (SRTF)
  • Priority Scheduling
  • Round Robin (RR)
• Interactive UI:
  • Add processes dynamically.
  • Visualize the Gantt Chart for each scheduling algorithm.
  • Error handling for invalid inputs.
• Standalone Core Algorithms:
  • The cpu_scheduling_algorithms.py file contains the core implementations of scheduling algorithms, independent of the GUI.
• Integrated Application:
  • The cpu_scheduling_app.py file combines the algorithms and an interactive UI in a single application.

Installation

1. Clone the repository:

   git clone https://github.com/mohamedyounis10/cpu-scheduling-app.git
   cd cpu-scheduling-app

2. Install dependencies:

   pip install customtkinter matplotlib pillow

3. Run the GUI application:

   python cpu_scheduling_app.py

Usage

Core Algorithm Usage

You can use the core algorithms independently by importing them from the cpu_scheduling_algorithms.py file. Example:

from cpu_scheduling_algorithms import FCFS, ProcessAttributes

processes = [
    ProcessAttributes(pid="P1", BurstTime=5, ArrivalTime=0),
    ProcessAttributes(pid="P2", BurstTime=3, ArrivalTime=2),
    ProcessAttributes(pid="P3", BurstTime=8, ArrivalTime=4),
]

result = FCFS(processes)
print(result)  # Output: [("P1", 0, 5), ("P2", 5, 8), ("P3", 8, 16)]

GUI Usage

1. Launch the application and add processes by filling out the fields for Process ID, Burst Time, Arrival Time, and optionally Priority/Time Quantum.
2. Select a scheduling algorithm.
3. Click "Run Algorithm" to visualize the Gantt Chart.
