This Is Why They Call It a Weakly-Ordered CPU: "On this blog, I’ve been rambling on about lock-free programming subjects such as acquire and release semantics and weakly-ordered CPUs. I’ve tried to make these subjects approachable and understandable, but at the end of the day, talk is cheap! Nothing drives the point home better than a concrete example.
If there’s one thing that characterizes a weakly-ordered CPU, it’s that one CPU core can read values from shared memory in a different order than another core wrote them. That’s what I’d like to demonstrate in this post using pure C++11."
