Hi Ralph, this is an additional information.
Here is the main part of output by adding "-mca rmaps_base_verbose 50".

So I added "-oversubscribe" and rerun, then it worked well as show below:

[node08.cluster:27019] [[56774,0],0] Filtering thru apps

[node08.cluster:27019] mca:rmaps:base: assigning rank 7 to node node08
I think something is wrong with treatment of oversubscription, which might
be
related to "#3893: LAMA mapper has problems"
