@pkce @sunfish Confusingly, what you call "concurrency" is what a bunch of people call "concurrency control": https://en.wikipedia.org/wiki/Concurrency_control That is, concurrency represents uncertainty about ordering of operations and concurrency control is how you keep it in check and ensure safety. Under that view, not every parallel program is concurrent. SIMD for example is parallelism but it does not involve uncertainty and therefore needs no concurrency control.
