Dear OpenMPI users,
Regarding to this previous post
<http://www.open-mpi.org/community/lists/users/2009/06/9560.php> from 2009,
I wonder if the reply
from Ralph Castain is still valid. My need is similar but quite simpler:
to make a system call from an openmpi fortran application to run a
third party openmpi application. I don't need to exchange mpi messages
with the application. I just need to read the resulting output file
generated
by it. I have tried to do the following system call from my fortran openmpi
code:
call system("sh -c 'mpirun -n 2 app_name")
but I get
**********************************************************
Open MPI does not support recursive calls of mpirun

Is there a way to make this work?
Best regards,
Alex
