[Mauiusers] MPI / IB setup

we have here a setup of Infiniband nodes, grouped around IB switches.
I wonder if it's possible to have MPI jobs run on a set of nodes that
are connected on the *same* IB switch.
I thought about special attributes for the nodes, but it is by no way
Let me be more precise :
- we have 64 nodes, connected by groups of 4 nodes per chassis.
- we have 4 "leaves" IB switches, all receiving 16 nodes (4 chassis) IB
... and 2 more spine IB switches.
We want the jobs fitting on 16 nodes to run on a set of nodes all
connected to the same leaf switch.
Does anyone have already configured such a setup ?
