CPU Scheduler Visualizer (OKernel v1.0.1)

OKernel is an interactive, browser-based Operating System simulation designed to help students master core OS concepts. It features a fully functional SysCore Engine that drives a realistic terminal interface and a visual CPU scheduler.

Features (v1.0.1)

SysCore Terminal

• Interactive Shell: A robust command-line interface with history, auto-completion (Tab), and colored output.

🚀 Key Features

• Cycle-Accurate Simulation: Visualizes CPU bursts, I/O waits, and Context Switching overheads tick-by-tick.
• SysCore Engine: A separated, pure-logic scheduler engine that drives the UI.
• Dynamic Configuration: Versioning and system status are managed via Database.
• Admin Terminal: A dedicated "God Mode" console for system management.

• Command Dispatcher: Support for complex sub-commands (e.g., syscore.cpu.info, syscore.algos.rr).
• Self-Documenting: Built-in help and API discovery via the syscore command.

CPU Scheduler Visualizer

• Algorithms: Round Robin (RR), Shortest Job First (SJF), First-Come First-Serve (FCFS), Shortest Remaining Time First (SRTF), Priority Scheduling.
• Real-Time Visualization: Dynamic Gantt chart rendering with process state tracking.
• Customizable: Adjust time quantum, add custom processes, and toggle algorithms on the fly.

Modern Architecture

• Tech Stack: React 18, TypeScript, Vite, TailwindCSS.
• Design System: Glassmorphism + Retro-Futuristic Terminal aesthetic (detailed in THEME.md).
• Routing: Namespace-based navigation (/dev/*).
