⚡ Intelligent CPU Scheduler Simulator

Description

The Intelligent CPU Scheduler Simulator is a project aimed at simplifying and enhancing the understanding of CPU scheduling algorithms through real-time visualizations. This simulator allows users to input process details such as arrival time, burst time, and priority, and provides a dynamic interface to visualize Gantt charts and compute key performance metrics like average waiting time and turnaround time.

Solution Architecture

🖥️ Frontend

• HTML5 and CSS3: For structuring and styling the user interface.
• JavaScript (ES6): For implementing scheduling logic and rendering real-time charts.
• Chart.js: To display Gantt charts and performance metrics.

🔄 Algorithm Implementation

1. FCFS: Processes are executed in the order of their arrival.
2. SJF: Shortest burst time processes are executed first.
3. Priority Scheduling: Processes with higher priority are executed first.
4. Round Robin: Processes are executed in cyclic order with a fixed time quantum.

Data Flow

1. User inputs process details through the interface.
2. Selected scheduling algorithm processes the data.
3. Results are displayed via Gantt charts and performance metric tables.
