I'm trying to update to openMPI 1.8.1 thru ssh and Myrinet
running a command as
/opt/openmpi/bin/mpirun --verbose --mca mtl mx --mca pml cm -hostfile
hostfile -np 16
when the hostfile contain only two nodes as
host1 slots=8 max-slots=8
host2 slots=8 max-slots=8
it runs perfectly but when the
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

While that resolve my problem with cross ssh authentication a command as

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

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.
