Re:Ask HN: Some examples of parallel but not concurrent proc... by jjaredsimpson on Friday December 01, 2017 @12:22PM (#15825387)
Vector addition in floating point registers is parallel but not concurrent.

Parallel means division of a task into separate parts which execute at the same instant in time.

Concurrent means separate task with overlapping lifetimes.

Parallel is contrasted with single threads of execution. And concurrent should be contrasted with serialization of task lifetimes.
