HELP setup on>>charmrun/mpirun & NAMD via torque

Hello All
I am trying to perform namd runs using Torque/maui and Ihave several
questions regaring the charmrun/mpirun portion especially.
 
When I submit the script below>
 
qsub script.txt
 
I see this in this running inthe queue
[nm67371@bwdl01-m001 Test06Proc]$ qstat -n
 
bwdl01-m001.brw.pharma.aventis.com:

[nm67371@bwdl01-m001 Test06Proc]$

But, when I do a ps on both nodes 14 and 13 I only can find my PID on
node 14 and not node 13.
So any ideas on how I can properly parrellize my jobs?
What is the relationship between mpirun and charmrun?
Thanks for any advice!
Dan
PS..
The two different scripts below have the same type of behaviour
