• flip-flopping between parallel and single-thread code

    in geophysical processing, you have both single-threaded and parallel-safe modules. Data flow may go like this:


    Now the single-threaded module may be defined so simply because it is so trivial and the programmer thought the message passing overhead was not
    worth it. But then does this not mean that the data is merged going into
    it, and then sprayed out again to multiple cores?
    So would it not be better to remain in parallel mode, by enabling the
    single threader to run parallel?
