Acquire and Release Fences
Explore the role of acquire and release fences in C++ concurrency to establish synchronization and ordering constraints between threads. Understand how these fences differ from atomic operations and how they prevent operation reordering, enhancing safe multithreading practices.

The most obvious difference between acquire and release fences and atomics with acquire-release semantics is that fences need no atomics. There is also a more subtle difference: the acquire and release fences are more heavyweight.
Atomic Operations vs Fences
For the sake of simplicity, I will now refer to acquire operations when I use fences or atomic operations with ...
