They are just as you say but while one run until the end (case 3
using --deamons-debug) the other hangs (Case 1)
in the case 1 even if is only in one node with plm_rsh_no_tree_spawn 1
flag (that as you say shouldn't do anything), the process hangs,
while in the case 2 without this flags in the
Forgive me, but I am now fully confused - case 1 and case 3 appear identical to
me, except for the debug-daemons flag on case 3.

What I mean with "another mpi process".
I have 4 nodes where there is process that use mpi and where initiated
using mpirun from the control node already running when I run the command
against any of those nodes it execute but when I do it against any other
node it fails if no_tree_spawn flag
I'm afraid I don't understand your comment about "another mpi process". Looking
at your output, it would appear that there is something going on with host
nexus17. In both cases, mpirun is launching a single daemon onto only one other
node - the only difference was in the node being used. The "n
I have try if another mpi process is running in the node already the

Hmmm...no, it worked just fine for me. It sounds like something else is going
on.
Try configuring OMPI with --enable-debug, and then add -mca plm_base_verbose 10
to get a better sense of what is going on.

I confess I haven't tested no_tree_spawn in ages, so it is quite possible it
has suffered bit rot. I can try to take a look at it in a bit

During the 1.7 series and for all follow-on series, OMPI changed to a mode
where it launches a daemon on all allocated nodes at the startup of mpirun.
This allows us to determine the hardware topology of the nodes and take that
into account when mapping. You can override that behavior by either
