Thread-Safe Singleton: Atomics
Explore how to implement a thread-safe singleton pattern in C++ using atomic operations. Understand the differences between sequential consistency and acquire-release semantics in memory models, and optimize singleton initialization by applying double-checked locking with atomics. This lesson guides you through challenges and best practices for concurrency-safe singleton design.

With atomic variables, my implementation becomes a lot more challenging; I can even specify the memory model for my atomic operations. The following two implementations of the thread-safe singletons are based on the previously mentioned double-checked locking pattern.
