My question is how fast is access to atomic variables in C++ by using the C++0x actomic<> class? What goes down at the cache level. Say if one thread is just reading it, would it need to go down to
GCC offers a nice set of built-in functions for atomic operations. And being on MacOS or iOS, even Apple offers a nice set of atomic functions. However, all these functions perform an operation, e.g.
