Rlaph,
Thanks for the reply. I should be able to build my own.

Hmmm...well, there -used- to be a tool that was distributed with the
1.2 series for doing just that, but I don't see it in the 1.2.7
release. Not sure when or how that got dropped - probably fell through
a crack.
Unfortunately, minus that tool, there is no clean way to shut this
down. However, you can re-use the universe name if you simply go to
your tmp directory, find the session directory for you, and just rm
-rf the directory with that universe name.
So you want to look for something like
"/tmp/openmpi-sessions-username@hostname_0/univ3" per your example
below, and blow the "univ3" directory tree away.
Sorry it isn't simpler - trying to re-release with that tool is
probably more trouble than it is worth now, especially given that the
"seed" operation isn't used anymore beginning with the upcoming 1.3
release.

Greetings,
I have a manager/worker application. The
manager is called "t2a" and the workers "w2d"
I launch the manager and each worker with
its own mpiexec with n=1. They connect using
various calls including MPI_Open_port,
MPI_Comm_accept, MPI_Comm_connect and
MPI_Intercomm_merge.
It works fine.
I am using the command:
orted --persistent --seed --scope public --universe univ3 --set-sid
to set up the universe and the mpiexec commands are:
mpiexec -np 1 --universe univ3 t2a
mpiexec -np 1 --universe univ3 w2d
mpiexec -np 1 --universe univ3 w2d
mpiexec -np 1 --universe univ3 w2d
Question:
What is the proper way to shutdown orted?
I have found that if I just kill orted then
I can't reuse the universe name.
Platforms and OpenMPI versions:
OS X openmpi-1.2.7 or openmpi-1.2.6 (ethernet)
Rocks openmpi-1.2.6 (Infiniband)
Thanks!
Tim
