Hi,
I've run into the same problem as discussed in the thread Lev Gelb: "Re:
[OMPI users] Recursive use of "orterun" (Ralph H
Castain)"<http://www.open-mpi.org/community/lists/users/2007/07/3655.php>
I am running a parallel python code, then from python I launch a
riding oversubscription

Also, there is absolutely no output from the second orterun-launched
program (even the first line does not execute.)
Cheers,
Lev

I'm unaware of any issues that would cause it to fail just because it is
being run via that interface.
The error message is telling us that the procs got launched, but then
orterun went away unexpectedly. Are you seeing your procs complete? We do
sometimes see that message due to a race condition
Hi -
I'm trying to port an application to use OpenMPI, and running
into a problem. The program (written in Python, parallelized
using either of "pypar" or "pyMPI") itself invokes "mpirun"
in order to manage external, parallel processes, via something like:
orterun -np 2 python myapp.py
