We have a spectrum of work going on in this area at ICASE,
we are both designing distributed compilers (Kali Fortran)
and designing tools to be used directly by programmers (PARTI).
All of this work is designed to provide the illusion of
shared memory on distributed machines, at least when using
parallel loop constructs (of course efficiency is a whole
other story ... but if data is well mapped it sometimes
works out well).
Our favorite applications areas are in unstructured meshes,
sparse matrices and adaptive problems although the compiler
effort also addresses regular problems.

Here are a few references: (we can supply preprints)
