Correction on this, this problem only occurs (with OpenMPI 1.2) when
I don't use mpirun to launch my process.
I know seems strange to most mpi users, it turns out that when using
OpenMPI and only needing one process (because I spawn everything else
I need), I had found it quicker just to la
I'm running OpenMPI 1.1 (v9704)and when a spawned processes exits the

We expect to have much better support for the entire comm_spawn process
in the next incarnation of the RTE. I don't expect that to be included
in a release, however, until 1.1 (Jeff may be able to give you an
estimate for when that will happen).
Jeff et al may be able to give you access to an
Open MPI currently does not fully support a proper disconnection of
parent and child processes. Thus, if a child dies/aborts, the parents
will abort as well, despite of calling MPI_Comm_disconnect. (The new RTE
will have better support for these operations, Ralph/Jeff can probably
give a better
Hi everybody,
I am trying to run a master/slave set.
Because of the nature of the problem I need to start and stop (kill)
some slaves.
The problem is that as soon as one of the slave dies, the master dies
also.
This is what I am doing:
MASTER:
MPI_Init(...)
MPI_Comm_spawn(sl
