Ostep Homework

This project is a collection of operating systems courseware and educational programming exercises designed for studying operating system design and implementation. It provides a set of concept simulators for modeling CPU scheduling, memory virtualization, and concurrency mechanisms.

The project includes specialized tools such as a concurrency simulation lab for experimenting with synchronization, a file system modeling suite for studying disk persistence and RAID configurations, and a process tree visualizer for displaying parent-child relationship hierarchies.

The software covers broader capability areas including process management through code generation and visualization, resource management for simulating memory and CPU abstractions, and persistence system simulation for data storage and recovery.

Features

Operating System Concepts - Provides educational material and simulations covering core operating system internals and architecture.

Operating System Curricula - Provides structured educational sequences and exercises covering low-level computer architecture and operating system implementation.

C System Simulations - Implements low-level system primitives and hardware constraints using the C programming language for educational modeling.

Fork and Exit Operations - Implements fundamental process creation and termination using the system fork and exit calls.

Virtualization Simulations - Simulates how CPU scheduling and memory management abstract physical hardware into process and address space abstractions.

Persistence Simulations - Provides models of non-volatile data storage and file system architectures for educational purposes.

Resource Coordination Simulations - Simulates process abstraction, CPU scheduling, and memory management to demonstrate system resource coordination.

Simulated Address Translators - Simulates page table walks and virtual-to-physical address translation within a controlled educational environment.

Block Storage - Models architectural patterns for managing data storage at the block level to emulate file systems and RAID.

File System Simulators - Simulates file system structures and verifies on-disk data integrity for studying persistence and RAID.

Concurrency Labs - Ships a practical environment for experimenting with threads, locks, semaphores, and condition variables.

Synchronization Simulations - Provides a simulation environment for practicing parallel execution synchronization using threads, locks, and semaphores.

Process Hierarchy Visualizations - Creates visual representations of system processes organized by their parent-child relationship lineages.

Condition Variables - Provides synchronization primitives that allow threads to wait for specific state changes via condition variables.

Trace-Based Flow Visualizers - Generates visual directed graphs reconstructed from process execution traces to map parent-child relationships.
