Yes - I suspect default integer size differences, and a difference in the
builds of mpi and amber too, and I would expect the potential for havoc (so
you have an mpi call that is expecting 8 byte integers, and you give it 4
byte integers...). But I don't know. I have seen wierd things before of
this sort, and they sourced from details about how the mpi libraries were
built.
