A group of potential MPI-IO users that Jean-Pierre and I recently talked to in
the ASCI program want the ability for MPI-IO to be told the name of a
format for the data to be dumped in, precisely for this purpose
(visualization). The idea is that a program that dumps data in a format
expected by the vusualization program could then be portable. It would be
a generalization of the three options we currently have when the file is
opened.
