Well, you have to setup nearly identical PEs like openmpi2, openmpi4  
with a fixed allocation rule of 2 or 4 respectively.

OTOH: Once I looked into Torque and found, that with "nodes=2:ppn=2"  
I got just one node with 4 slots in total of course. I don't know,  
whether it can still happen to get such a distribution.
