The parallelize mechanism in 7, works by starting extra kernels, that 
can each do any calculation they want, but I can't quite see how that 
will help you with your calculation.

It might be an idea to post the problem, because if there is a way round 
your difficulty, someone here will suggest it!

Memory problems can be greatly eased by moving to a 64-bit architecture. 
  Many modern computers are already 64-bit capable, and in that case, 
all that is needed is to change to a 64-bit operating system and 
re-install Mathematica. However, I'd start by posting your actual 
problem if possible.
