Computer Architecture for CPUs. Compilers for... well... compilers.

Yea, computer architecture is what you'll want to learn if you want to learn how CPU's work under-the-hood. The gist of the topic is how instruction sets work.

So I don't keep bringing this post off topic, I'll PM you from now on. LOL

ISA = Instruction Set Architecture. If you want to learn how they work under the hood, study microarchitecture.

BTW, under-the-hood knowledge helps a LOT for high-performance coding.

Or at very least it lets you understand WHY some "tricks" Don't speed things up at all 🙂. It is definitely needed to know how to get optimum performance though.

Yeah, I'm getting that impression the deeper I get into HPC. Strangely most of the people around me haven't had any formal training in "under the hood" knowledge, and it hadn't even really been suggested to me yet. Doh guess I should rethink my course plan.

Sorry to rain on the parade, but to understand whats going on, at least from classes, you'll need to take graduate level courses in architecture. Thats probably not worth your time. You can get a vague idea of the kind of tradeoffs involved in an intro course. I'd recommend auditing the intro course if you're curious.
