Modern C++ Concurrency: The Complete Guide (From C++11 to C++26)
For decades, writing safe, high-performance concurrent C++ required navigating a minefield of platform-specific APIs and undefined behavior. This article provides an exhaustive examination of the standard's solution, tracing the language's evolution from C++11's foundational thread-and-mutex primitives to the composable, zero-overhead asynchronous execution models of C++26. Dive into a rigorous taxonomy detailing the theoretical underpinnings of thread-level parallelism, stackless coroutines, portable SIMD, and the forthcoming sender-receiver framework for modern systems programming.
