Me, too. Users are asking me for ppn=x functionality like Torque/PBS
has, and I'm finding pretty complicated to implement on SGE.
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.
