No, that's not the thing I'm talking about. Those are the different ordering modes you can specify on atomic operations. Rather, there's a panoply of definitions like "inter-thread happens-before" and "synchronizes-with" and "happens-before", and those are the ones I don't follow closely. It gets even more confusing when you're reading academic papers on weak memory models.
