Thanks, Ralph!
Adding MAC parameter '
plm_rsh_no_tree_spawn' solves the problem.
If I understand correctly, the first layer of daemons are three nodes, and
when there are more than three nodes the second layer of daemons are spawn.
So my problem is happened when MPI processes are launched by the
The problem is with the tree-spawn nature of the rsh/ssh launcher. For
scalability, mpirun only launches a first "layer" of daemons. Each of those
daemons then launches another layer in a tree-like fanout. The default pattern
is such that you first notice it when you have four nodes in your allo
Hello everyone,
I am running a simple helloworld program on several nodes using OpenMPI
1.8. Running commands on single node or small number of nodes are
successful, but when I tried to run the same binary on four different
nodes, problems occurred.
I am using 'mpirun' command line like the follo
I suppose one initial question is: what version of Open MPI are you
running? OMPI 1.3 should not be attempting to ssh a daemon on a local
job like this - OMPI 1.2 -will-, so it is important to know which one

It's generally useful to include that information in your report - I

Anyway, I would guess that the problem you ar
