I would suggest checking out SMS:

It is a system aimed at the weather community. You add HPF-like
directives, and the system does the rest. We have seen O(100) speedup
on O(100) nodes... for a real code used for production air travel
weather prediction in the US.

It only does some kinds of stencils and some kinds of spectral codes,
and it only does F77, but if it does what your code uses...
