Thanks to both you and David Gunter. I disabled pty support and
it now works.
There is still the issue of the mpirun default being "-byslot", which
causes all kinds of trouble. Only by using "-bynode" do things work
properly.

There is a known issue on BProc 4 w.r.t. pty support. Open MPI by

pipes if ptys are not available.
You can "safely" ignore the pty warnings, or you may want to rerun
configure and add:
--disable-pty-support
I say "safely"
You can eliminate the "[n17:30019] odls_bproc: openpty failed, using
pipes instead" message by configuring OMPI with the --disable-pty-
support flag, as there is a bug in BProc that causes that to happen.

Hi
I have been testing OpenMPI 1.2, and now 1.2.1, on several BProc-
based clusters, and I have found some problems/issues. All my
clusters have standard ethernet interconnects, either 100Base/T or
Gigabit, on standard switches.
The clusters are all running Clustermatic 5 (BProc 4.x), and range
