Sorry I didn't offer additional clarity. Parallelism generally implies a task that can be split into smaller chunks, which are then processed more or less simultaneously. Concurrency, by contrast, refers to a situation in which multiple executions of the same task can occur concurrently. I think it's important to get that right when talking about dist. systems simply to avoid potential confusion.
