Parent article: Memory part 2: CPU caches
"The text doesn't touch on memory consistency at all"
Sorry, not true. It describes how caches of different x86 CPUs interact, but doesn't say it only describes x86, falsely suggesting that is how every other machine does it too. It leaves the reasonable reader under the impression that programmers don't need to know anything about memory consistency. That's not entirely true even on x86, but is just false on most non-x86 platforms. If Ulrich is writing for people programming only x86, the article should say so without quibbling. If not, it should call out places where it is describing x86-specific behavior.
