FWIW, I think these kinds of things usually fall in the scope of
concurrency rather than parallelism.
I have no idea what the difference is supposed to be; as far as I’m
concerned, they’re synonyms.
Think of a single lock-free algorithm, say a queue, that is servicing multiple threads. Well, that takes away from an embarrassingly parallel algorithm, vs one queue per thread. Even if after a thread obtains work from said queue and can operate in parallel on it independently, that single queue causes the overall operation to not be embarrassingly parallel anymore. Not sure if that helps with your question, but it's just my view...
