cpu-scheduling-visualizer

Features

CPU Scheduler

Supports multiple scheduling algorithms:

• FCFS (First Come First Serve)
• SJF (Shortest Job First) / Preemptive and Non Preemptive
• Round Robin
• Priority Scheduling / Preemptive and Non Preemptive

For each algorithm the application provides:

• Editable process table
• Arrival time
• Burst time
• Priority
• Dynamic process addition/removal
• Round Robin quantum configuration
• Animated execution playback
• Adjustable playback speed
• Gantt chart visualization
• Waiting time calculation
• Turnaround time calculation
• Average waiting time
• Average turnaround time
• Current execution indicator
• Per-process execution timeline

• Enter any number of seconds
• Large digital clock display
• Start and reset controls
• Progress bar visualization
• Color changes as time runs out
• Flashing "TIME'S UP!" notification
• Uses Unix 'alarm()' and signal handling
