Master CPU Scheduling Algorithms

See how an operating system picks which process runs next. CPU Scheduler Pro turns classic CPU scheduling into colorful, interactive timelines you can explore on your phone.

Algorithms Included

FCFS (First Come First Serve)

Non-preemptive scheduling in arrival order.

SJF (Shortest Job First)

Non-preemptive scheduling that favors shorter jobs.

SRTF (Shortest Remaining Time First)

Preemptive scheduling based on remaining time.

Round Robin

Preemptive scheduling with an adjustable time quantum (1–20 ms).

Priority Scheduling

Non-preemptive and preemptive priority scheduling (lower number = higher priority).

Visual Features

Interactive Gantt Charts

• Tap a time block for start, end, duration, and idle details

• Scroll the timeline horizontally

• Zoom in and out

• Animate a playback line across the schedule

• Unique colors per process; idle time shown with cool gradients (can be hidden in settings)

• Gantt display styles: Modern, Classic, Minimal, 3D

Performance Metrics

• Average waiting time

• Average turnaround time

• CPU utilization

• Throughput

• Per-process waiting, turnaround, and response times

• Bar chart comparing average waiting time across all built-in algorithms

Process Manager

• Add, edit, delete, and duplicate processes

• Set burst time, arrival time, and priority

• Reorder processes with move up / move down

• Quick presets: Student, Office, Gaming, Heavy

Appearance & Settings

• Themes: Classic, Neon, Matrix, Pastel, Sunset, Oceanic, Forest, Cosmic

• High contrast mode

• Color vision options: None, Protanopia, Deuteranopia

• Default Round Robin quantum

• Animation speed: Slow, Normal, Fast

• Gantt style selector

• Show or hide idle CPU time on the chart

• In-app privacy policy

• Reset all settings to defaults

Export & Share

• Export metrics as CSV, JSON, or PDF (Android share sheet)

• Export the current schedule as CSV
