problem
Modern operating systems rely heavily on CPU scheduling algorithms to determine how processes are allocated processor time. These algorithms directly influence system responsiveness, throughput, and resource utilization. However, understanding how scheduling algorithms behave in practice can be difficult for students and early-stage developers.
solution
The Intelligent CPU Scheduler was developed as an interactive simulator that allows users to experiment with multiple scheduling algorithms and observe their behavior in real time. The application enables users to input process attributes such as arrival time, burst time, and priority values, and then simulate scheduling based on the selected algorithm.
The Intelligent CPU Scheduler project emerged from the challenge many students face when studying operating system scheduling algorithms. While the theoretical principles behind CPU scheduling are well documented, visualizing how processes are actually executed over time can be difficult using traditional learning methods.
Students typically learn scheduling algorithms by solving static examples on paper. These exercises involve calculating waiting times, determining execution order, and drawing Gantt charts manually. Although these tasks help build conceptual understanding, they do not fully demonstrate how scheduling decisions affect overall system behavior.
This observation led to the idea of developing a simulator that could bring CPU scheduling algorithms to life through interactive visualization. Instead of manually computing results, users would be able to input process parameters and instantly observe how different algorithms handle the same set of processes.
The system was designed to replicate the behavior of common scheduling algorithms used in operating systems. Each process is defined by parameters such as arrival time and burst duration. Once the user selects a scheduling strategy, the simulator calculates the execution order and generates a visual timeline representing CPU allocation.
