Thx to you and others for the suggestions (I upvoted everyone and appreciate it). Good point that CUDA is its own world and won't really give me that pure software feel. Part of it might be me getting old and missing the days of my youth where I could code non-stop for a week. Just want to get back into the flow. I found one of my old File Systems text books the other day .. maybe I'll brush up on that with C++. Defn excited by async io in general, and totally unclear on how that works with modern C++. I guess boost:asio is a good starting point. Appreciate the pointer! In the old days, I'd spawn a bunch of threads but that is definitely old school (gotta checkout coroutines in C++!). I also fell in love with Systems programming in my youth writing socket software. So that is also a nice suggestion.
