I'm also a computer scientist(y) person, and the separation of parallelism and concurrency has never been quite clear; indeed, the meanings seem artifically separated. Nonetheless - I understand concurrency to be a notion such as coroutines, and parallelism to mean, you know, things happening at the same time.
