Concurrency in C++: Multithreading, Asynchrony, and Parallelism

Modern programs increasingly require efficient use of multi-core processors. The book "Concurrency in C++" is a practical guide that will help you master all aspects of parallel and asynchronous programming in C++. Whether you are writing a high-load server, a game engine, or simply want to speed up data processing, this book will be your reliable companion.

What is this book about?

The book covers a full range of topics related to concurrency in C++:

• Basics of Multithreading: creating and managing threads with std::thread, synchronization via mutexes, condition variables, and locks.
• Asynchronous Programming: working with std::async, std::future, and std::promise, as well as callback patterns and coroutines (C++20).
• Atomic Operations and Lock-Free Structures: using std::atomic, C++ memory models, and writing lock-free algorithms.
• Advanced Techniques: thread pools, parallel algorithms from STL (std::execution), working with shared data, and avoiding deadlocks.
• Testing and Debugging: tools for finding data races, profiling multithreaded code, and writing deterministic tests.

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 and want to delve deeper into concurrency. It will be useful for:

• Developers of server applications and high-load systems.
• Specialists in game engineering and real-time data processing.
• Engineers working with financial systems, robotics, or embedded systems.
• Anyone who wants to write fast and safe multithreaded code.

What will you learn?

After reading the book, you will be able to:

• Properly design the architecture of multithreaded applications.
• Avoid common mistakes: data races, deadlocks, and performance issues.
• Use modern C++11/14/17/20 features for concurrent programming.
• Choose between threads, tasks, and coroutines depending on the task.
• Optimize performance using profiling and lock-free algorithms.

Each chapter contains practical code examples that can be immediately applied in real projects. The book is written in a lively style, with an emphasis on practice and best global practices. Discover the world of concurrent C++ — and your programs will become faster, more reliable, and more scalable!
