>> Multiple threads on multiple CPUS in the same address space work fine, if you work in a language that supports it well. Go and Rust do; most other popular languages are terrible at it. I find OpenMP for C and C++ to be simple and effective. You do have to write functions that are safe to run in parallel, and Rust will help enforce that. But you can write pure function in C++ too and dropping a #pragma to use all your cores is trivial after that.
