That's a mistake. But probably non-trivial to fix.
Could you explain what you meant by that? There is no "fix"; Open

Hi,
MPI_COMM_WORLD is set to a large integer (1140850688) in MPICH2 so I
wonder if there is something in HDF5 and/or NetCDF4 that doesn't

Hi,
One question: you *are* using different HDF5/NetCDF4 installations for
Open MPI and MPICH2, right? I.e., all the software that uses MPI needs
to be separately compiled/installed against different MPI
implementations. Case in point: if you have HDF5 compiled against
MPICH2, it will not w

Hello,
I'm having a problem with MPI_COMM_WORLD in Fortran 90. I have tried
with OpenMPI versions 1.2.6, 1.2.8 and 1.3. Both versions are compiled
with the PGI 8.0-2 suite. I've run the program in a debugger and with
