In this post, our tour through the c++ memory model goes one step deeper. Until now, the posts were only…
Atomics
In addition to booleans, there is atomics for pointers, integrals, and user-defined types. The rules…

Sequential Consistency
The atomics are the base of the C++ memory model. Per default, sequential consistency is applied.
The…

The Atomic Flag
Atomics guarantee two characteristics. On the one hand, they are atomic, on the other, they provide synchronization…
