I have some experience with PP and it is an excellent piece of software,
very simple and usefull.
Nevertheless, it may give some problems importing modules in the
submit() method. If you have problems try to import the modules inside
your PP function, it will be less efficient but it will work!!!!! (you
will have nProcesses importing the same module at the same time)
I did some PP for interpolations were I created the total grid and
semi-variogram and them split everything into sub grids and interpolated
each sub-grid in different processors.
Also look at the callback example of the PP page it may give you an
ideia of the final class that will assemble the final output
