| ||Ask HN: Some examples of parallel but not concurrent processing|

|Lately I've been studying the different async workflows and the most confusing bit (so far) is the difference between concurrent execution and parallel execution.|
I have examples for concurrent-not-parallel, like single threaded processes or a multi-threaded program on a single thread processor.
What I cannot find are examples of scenarios where the execution is parallel, but not concurrent. TBH, it seems impossible (so far).
Wikipedia did give me one - Bit-level parallelism. But that topic is a bit out of reach for me (again, so far).
Can anyone give me a more simple parallel-not-concurrent execution scenario?
