Hi Ralph,
I found the reason. I attached the main part of output with 32
core node(node03) and 8 core node(node05) at the bottom.
>From this information, socket of node03 includes numa-node.
On the other hand, numa-node of node05 includes socket.
The direction of object tree is opposite.
Since "-map-by socket" may be assumed as default,
for node05, "-bind-to numa and -map-by socket" means
upward search. For node03, this should be downward.
I guess that openmpi-1.7.4rc1 will always assume numa-node
includes socket. Is it right? Then, upward search is assumed
in orte_rmaps_base_compute_bindings even for node03 when I
put "-bind-to numa and -map-by socket" option.

[node03.cluster:15508] mca:rmaps: compute bindings for job [38286,1] with
policy NUMA
[node03.cluster:15508] mca:rmaps: bind upwards for job [38286,1] with
bindings NUMA
[node03.cluster:15508] [[38286,0],0] bind:upward target NUMANode type
Machine
That's the reason of this trouble. Therefore, adding "-map-by core" works.
(mapping pattern seems to be strange ...)
