C++20 Thread Safety with std::atomic_ref

Writing multithreaded applications in C++ requires precise control over shared memory to prevent catastrophic data races. With the introduction of std::atomic_ref in C++20, developers gained a powerful tool to perform atomic operations on non-atomic objects temporarily, optimizing both performance and safety. This text-based course guides you through the mechanics of concurrent memory access, ensuring your parallel code is robust and standard-compliant. By the end of this course, you will confidently apply atomic operations to existing data structures, manage memory orderings, and write thread-safe C++ code without relying on heavy synchronization primitives. What you'll learn: Understand the foundational concepts of data races, thread safety, and memory consistency models; Apply std::atomic_ref to existing non-atomic variables for safe, temporary concurrent access; Configure atomic operations using modern memory ordering constraints for optimal hardware performance; Avoid common concurrency pitfalls like torn reads, undefined behavior, and lock contention; Practice implementing thread-safe algorithms using modern C++ design patterns. The course begins with essential concurrency terminology and core memory concepts before guiding you step-by-step through practical implementation patterns and real-world multithreaded scenarios. This course is designed for intermediate C++ developers who want to transition into modern concurrency, with no prior experience in C++20 standard library atomic utilities required.
