This review seems to equate parallelism and concurrency as the same thing and they are not.
As I understand it, the parallelism is about task execution and concurrency is about task structure. Or, as Rob Pike said:
"Concurrency is about dealing with lots of things at once. Parallelism is about doing lots of things at once."
He said that in his Concurrency is not Parallelism talk.

  in the English vernacular when you deal with something you do something.
