Dominic,
at first, you might try to add
call MPI_Barrier(comm,ierr)
between
if (file_is_there .and. irank.eq.iroot) call
MPI_FILE_DELETE(file,MPI_INFO_NULL,ierr)
and
call
MPI_FILE_OPEN(comm,file,IOR(MPI_MODE_WRONLY,MPI_MODE_CREATE),MPI_INFO_NULL,iunit,ierr)
/* there might me a race condition, i am not sure about that */
fwiw, the
STOP A configuration file is required
error message is not coming from OpenMPI.
it might be indirectly triggered by an ompio bug/limitation, or even a
bug in your application.
did you get your application work with an other flavor of OpenMPI ?
e.g. are you reporting an OpenMPI bug ?
or are you asking some help with your application (the bug could either
be in your code or in OpenMPI, and you do not know for sure)
i am a bit surprised you are using the same fileview_node type with both
MPI_INTEGER and MPI_REAL_SP, but since they should be the same size,
that might not be an issue.
the subroutine depends on too many external parameters
(nnodes_, fileview_node, ncells_hexa, ncells_hexa_, unstr2str, ...)
so writing a simple reproducer might not be trivial.
i recommend you first write a self contained program that can be
evidenced to reproduce the issue,
and then i will investigate that. for that, you might want to dump the
array sizes and the description of fileview_node in your application,
and then hard code them into your self contained program.
also how many nodes/tasks are you running and what filesystem are you
running on ?
Cheers,
Gilles

Gilles,
I do not have the latest mpich available. I tested using openmpi
version 1.8.7 as well as mvapich2 version 1.9. both produced similar
errors. I tried the mca flag that you had provided and it is telling
me that a configuration file is needed.
all processes return:
STOP A configuration file is required
I am attaching the subroutine of the code that I believe is where the
problem is occuring.

Dominic,
this is a ROMIO error message, and ROMIO is from MPICH project.
at first, I recommend you try the same test with the latest mpich,
in order to check
whether the bug is indeed from romio, and has been fixed in the
latest release.
(ompi is a few version behind the latest romio)
would you be able to post a trimmed version of your application
that evidences the test ?
that will be helpful to understand what is going on.
you might also want to give a try to
mpirun --mca io ompio ...
and see whether this helps.
that being said, I think ompio is not considered as production
ready on the v1.10 series of ompi
Cheers,
Gilles

It is an error coming from openmpi.
