Looking at the web page for POP (http://climate.lanl.gov/Models/POP/
index.shtml), it looks like POP 1.2 is pretty ancient. I gather from
your text that later versions work ok ("POP 2").

My first guess -- knowing nothing about the POP code itself -- is
that there is a bug in the POP 1.2 code such that it is passing a bad
parameter to MPI_CART_SHIFT, and that later versions (POP 2) fixed
the problem.

Do you know if this is the case?
