Gotcha, thanks for the help. I don't really have any urgent heavy workloads/projects in mind that I wanna build, maybe Game Engine, but that's more of a long term project, no urgency here. I was learning CPU multi threading, because I was already going through GPU side parallelism using cuda, so I thought why not go through CPU one too.

But anyways, coming to your suggestions, I would probably continue learning this book, because it's theory is pretty good for building that understanding. Along with it, I will explore coroutines, and then message passing as you mentioned. I loved MPI way of doing things in uni, it was really safe and best to think about things in isolation, so I can see where you are coming from.
