The simulator is used to schedule multiple processors. A Process Scheduling Simulator is a tool designed to simulate and visualize how a CPU schedules processes using various scheduling algorithms. It provides a dynamic environment to demonstrate algorithms' functionality, efficiency, and differences, making it a useful educational and analytical tool for understanding process management in operating systems.
Key Features of a Process Scheduling Simulator:
1. Simulation of Algorithms:
• First-Come, First-Served (FCFS): Processes are scheduled in the order they arrive.
• Shortest Job Next (SJN): The process with the shortest burst time is executed next.
• Priority Scheduling: Processes are scheduled based on priority values.
• Round-Robin (RR): Processes are scheduled in time slices, cycling through them.
• Multilevel Queue Scheduling: Processes are divided into queues with different scheduling policies.
• Multilevel Feedback Queue: Allows dynamic movement between queues based on behaviour.
2. Visualization:
• Gantt charts to represent the scheduling timeline.
• Process tables showing arrival, burst, completion, turnaround, and waiting times.
3. User Input Options:
• Add processes with parameters like arrival time, burst time, and priority.
• Configure time quantum for round-robin scheduling.
4. Performance Metrics:
• Average waiting time.
• Average turnaround time.
• CPU utilization and throughput.
5. Interactive Environment:
• Modify processes during runtime for dynamic analysis.
• Toggle between algorithms to compare performance.
6. Educational Benefits:
• Helps students and professionals understand CPU scheduling concepts.
• Demonstrates the impact of scheduling choices on system performance.
Applications:
• Teaching and learning in operating systems courses.
• Analyzing and comparing scheduling algorithms.
• Demonstrating real-world scenarios in CPU scheduling and process management.
