Concurrency in C++: Parallel and Asynchronous Programming

Modern applications demand maximum performance, and multi-core processors have become the standard. The book "Concurrency in C++" is a comprehensive guide to writing efficient, safe, and scalable parallel code in C++. You will learn to use all the features of the C++ standard library for working with threads, synchronization, and asynchronous operations.

The book is structured from simple to complex and is suitable for developers already familiar with the basics of C++ (syntax, classes, STL). You will start with basic concepts: creating threads (std::thread), protecting data with mutexes (std::mutex), condition variables (std::condition_variable). Then you will move on to advanced topics: atomic operations, the C++ memory model, lock-free data structures, design patterns for concurrent systems.

Special attention is paid to practical aspects:

• Asynchronous tasks — using std::async, std::future, and std::promise to organize non-blocking calls;
• Parallel algorithms — applying std::parallel and std::execution to speed up data processing;
• Debugging and profiling — tools for finding data races, deadlocks, and performance bottlenecks;
• Lock-free programming — creating high-performance lock-free structures (queues, stacks, hash tables).

Each chapter contains real code examples ready to compile and exercises to reinforce the material. You will learn how to avoid common mistakes: deadlocks, data races, caching issues. A separate section is dedicated to integrating concurrency with existing projects and refactoring single-threaded code.

Who is this book for?

• C++ developers looking to improve the performance of their applications;
• Systems programmers working with high-load services;
• Students and teachers studying parallel computing;
• Anyone who wants to understand the intricacies of the C++ memory model and atomic operations.

After reading this book, you will be able to confidently design concurrent systems, efficiently use multi-core processors, and write code that scales without losing performance. Become an expert in concurrent programming in C++!
