Well, then, is there really such a thing that extracts threads from those
horrible C codes and generates MPI code? Not that I believe it is impossible
(since I work for a company that does a similar thing) but I would like to know
which autoparallel MPI code the posters had in mind. Is there a market for
that kind of a compiler?
