Introduction to C++ Concurrency for High-Performance Coding

Writing fast software requires taking full advantage of modern multi-core processors, but concurrent programming in C++ can feel daunting due to the risk of bugs like data races and deadlocks. This text-based course guides you step-by-step through the core concepts of multithreading so you can write high-performance code with confidence. By the end of this course, you will transition from writing single-threaded programs to designing safe, efficient concurrent applications. You will learn to manage multiple threads of execution, synchronize shared data, and apply modern C++ concurrency models to avoid common performance bottlenecks. What you'll learn: Understand the fundamental terminology of threads, processes, and shared memory; Create and manage threads using modern C++ standards, including lifecycle management with std::jthread; Protect shared data and prevent data races using mutexes, locks, and RAII principles; Apply atomic operations and understand lock-free programming basics for high-performance scenarios; Diagnose and avoid common concurrency pitfalls such as deadlocks, livelocks, and thread starvation; Practice writing thread-safe code through structured, written exercises and code analysis. The course begins with foundational definitions of multi-core processing before moving into practical code examples, synchronization patterns, and modern performance guidelines. This course is designed for C++ developers who are new to multithreading and concurrency, requiring no prior experience with concurrent programming.
