Concurrency in C++: A Practical Guide to Multithreaded Programming

The book "Concurrency in C++: A Practical Guide to Multithreaded Programming" is a comprehensive guide for developers who want to master modern approaches to writing multithreaded and asynchronous applications in C++. The author, Alexey Ivanov, an experienced system engineer and teacher, systematically covers all key aspects of concurrent programming, starting from the basics and ending with complex synchronization patterns.

What is this book about?

The book covers a full range of topics necessary for effective work with concurrency in C++:

• Basics of Multithreading: creating and managing threads with std::thread, passing arguments, handling exceptions in threads.
• Data Synchronization: mutexes (std::mutex, std::shared_mutex), locks (std::lock_guard, std::unique_lock), condition variables (std::condition_variable).
• Atomic Operations: std::atomic, C++ memory models (memory ordering), lock-free programming and preventing data races.
• Asynchronous Tasks: std::async, std::future, std::promise, std::packaged_task — writing asynchronous code without explicit thread management.
• Parallel Algorithms: using std::execution::par to parallelize standard algorithms (C++17).
• Design Patterns: thread pool, producer-consumer, reader-writer lock, barriers and latches (std::barrier, std::latch in C++20).
• Debugging and Profiling: tools for finding deadlocks, data races, and bottlenecks in multithreaded code.

Who is this book for?

The book is intended for intermediate and advanced C++ developers who are already familiar with the basics of the language (pointers, templates, STL) and want to delve into concurrency topics. It will be useful for:

• Programmers of high-load servers and network applications.
• Developers of games and graphics engines where performance is critical.
• Engineers working on real-time systems or embedded systems.
• Anyone who wants to write safe and efficient multithreaded code in C++.

What will the reader learn?

After reading the book, you will be able to:

• Confidently use the C++ standard thread library (std::thread, mutexes, futures).
• Understand the C++ memory model and correctly choose the ordering of atomic operations.
• Avoid common mistakes: deadlock, livelock, data races.
• Design scalable concurrent systems using modern patterns.
• Apply parallel algorithms to speed up computations.
