CPU Scheduling Simulator

Overview

The CPU Scheduling Simulator is a Java-based application designed to simulate various CPU scheduling algorithms. It provides a graphical user interface (GUI) that allows users to input process parameters and visualize the scheduling process. This tool is beneficial for understanding how different scheduling algorithms manage process execution in an operating system environment.

Features

• Graphical User Interface (GUI): Intuitive and user-friendly interface for inputting process details and viewing scheduling results.
• Multiple Scheduling Algorithms: Supports simulation of various CPU scheduling algorithms.
• Process Visualization: Displays the order of process execution and relevant metrics for analysis.

Supported Scheduling Algorithms

• FCAI Scheduling: A custom algorithm that prioritizes tasks based on a combination of factors, including priority, arrival time, and remaining burst time.
• Priority Scheduling: Executes processes based on priority levels.
• Shortest Job First (SJF):
  • Standard SJF: Selects the process with the smallest execution time.
  • SJF with Starvation Solution: Implements aging to prevent long waiting times for low-priority processes.
• Shortest Remaining Time First (SRTF):
  • Standard SRTF: Selects the process with the smallest remaining execution time.
  • SRTF with Starvation Solution: Uses aging to balance execution fairness and prevent process starvation.
