As someone who does large scale computational work for a living, stuff like this is close to my heart. I often run into serious memory and run time constraints due to poorly written codes that have rather dumb understanding of the real underlying machine implementation that modern processors actually have rather than this imaginary PDP-11 that we've been brought up to believe. I wonder how much I could save (and how many more sims I could run) if my codes were rewritten in a language that has an abstract system that is much more cleanly and simply translated to what the computer actually does in 2018.
