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 :-)))
