As a norm, you want to avoid inter node communication as much as
possible. This usually means each processing element has to be able to
process as much information as possible and as the problem allows. For
so called embarrassingly parallel problems you obtain much better
results if you invest in some fast PEs than in a larger ammount of not
so fast ones. You have to be careful here: if you go for the SMP
solution, don't forget to double the ammount of RAM at each node,
otherwise you might find yourself in a position where the problem size
you can solve hasn't increased much.
