Hi, it would *if* it take not time to distribute the data to the other CPU's *and* it would take not time to get the values back. Since the overhead of sending and getting data ist extrem high you need a really time consuming function to outweight it. In general I can't tell you if there is a speed up. But I can tell you that our students in the parallel processing laboratory never get a speed up for the example tasks :-))) Regards Jens Orestis Vantzos wrote: > > The single most common Mathematica operation I use is Map (and variations of > it, such as Table)...I don't see why it couldn't be made to run > concurrently.
