Cannot get correct rank and size

[MINAMI Akihiko]

Hi
I am using patched Torque 1.1.0 and mpiexec with mpich2 on Dual Opteron machines. 
Configure option to compile mpiexec is --with-pbs=/usr/lib/torque. 
As I tried to run runtests.pl after the installation, I got following stdout.  
--------------------
hello from 0/1 hostname node02.cluster pid 2542 with 0 args:
hello from 0/1 hostname node01.cluster pid 4496 with 0 args:
hello from 0/1 hostname node01.cluster pid 4495 with 0 args:
hello from 0/1 hostname node02.cluster pid 2543 with 0 args:
--------------------
It seems that correct rank and size are not obtained. 
Is there any installation problem or wrong usage?
Any help would be appreciated.
