Hi Ralph, this is just for your information.
I tried to restore previous orte_rmaps_rr_byobj. Then I gets the result
below with this command line:
mpirun -np 8 -host node05,node06 -report-bindings -map-by socket:pe=2
-display-map -bind-to core:overload-allowed ~/mis/openmpi/demos/myprog

Then I add "-hostfile pbs_hosts" and the result is:
[mishima@manage work]$cat pbs_hosts
node05 slots=8
node06 slots=8
[mishima@manage work]$ mpirun -np 8 -hostfile ~/work/pbs_hosts

I think previous version's behavior would be close to what I expect.
