Subject: Re: [OMPI users] openmpi configuration error?

Hi Ben

My guess is that your sys admins may have built NetCDF
with parallel support, pnetcdf, and the latter with OpenMPI,
which could explain the dependency.
Ideally, they should have built it again with the latest default OpenMPI
(1.6.5?)

Check if there is a NetCDF module that either doesn't have any
dependence on MPI, or depends on the current Open MPI that
you are using (1.6.5 I think).
A 'module show netcdf/bla/bla'
on the available netcdf modules will tell.

If the application code is old as you said, it probably doesn't use
any pnetcdf. In addition, it should work even with NetCDF 3.X.Y,
which probably doesn't have any pnetcdf built in.
Newer netcdf (4.Z.W > 4.1.3) should also work, and in this case
pick one that requires the default OpenMPI, if available.

Just out of curiosity, besides netcdf/4.1.3, did you load openmpi/1.6.5?
Somehow the openmpi/1.6.5 should have been marked
to conflict with 1.4.4.
Is it?
Anyway, you may want to do a 'which mpiexec' to see which one is
taking precedence in your environment (1.6.5 or 1.4.4)
Probably 1.6.5.

Does the code work now, or does it continue to fail?

I hope this helps,
Gus Correa
