I was wrong about this being a problem with OpenMPI's version of
ROMIO. The OpenMPI guys have synced up fairly recently with the
OpenMPI in MPICH2.
ROMIO, even the very latest in CVS version, doesn't support resized
Looks like you'll have to take George's alternate idea of MPI_UB and
We'll let the OpenMPI guys know when resized support is in place.
Sorry for the confusion.
