I've actually had a lot of luck on our cluster with putting the parallel
parts of the code outside of itk.  I had a huge amount of trouble when I
thought of all my slices as one multi gigabyte image. When I started to
think of it as slices that could be processed independently I was able
to process all the images with only a bash script and programs from the
itk example directory. 

The bad part is there's no way that code will just run 20 times faster
just because it's on a cluster.  You really have to think about what
will be parallel and what will not.
