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.
