Philosophers: A Multithreaded Concurrency Challenge

Project Overview

The Philosophers project is an advanced systems programming challenge that explores concurrent programming, thread synchronization, and resource management through a metaphorical dining scenario. By implementing a sophisticated simulation of philosophers sharing limited resources, the project provides a deep dive into the complexities of parallel computing.

Technical Concept

The Philosophical Dilemma

The project models a classic concurrent programming problem: philosophers seated around a table, each requiring two forks to eat. This scenario serves as a compelling framework for exploring critical synchronization challenges:

• Resource contention
• Deadlock prevention
• Fair resource allocation
• Real-time process management

Implementation Approaches

Mandatory Solution: Threaded Implementation

• Utilizes POSIX threads (pthreads)
• Implements mutex-based fork management
• Handles up to 200 philosophers simultaneously
• Precise timing control with millisecond-level accuracy

Bonus Solution: Process-Based Approach

• Implements philosophers as separate processes
• Manages resources using semaphores
• Demonstrates inter-process communication
• Provides an alternative synchronization strategy

Key Technical Challenges

Synchronization Mechanics

• Preventing deadlocks
• Ensuring fair fork distribution
• Avoiding philosopher starvation
• Implementing precise state tracking
