Using IMB to test multiple host p2p communications simultaneously

I was wondering if we can use the -multi option in IMB to test multiple p2p MPI connections.

In a cluster of 2M nodes can we instruct IMB to create M p2p MPI communications simultaneously, with each end-point pair being a distinct oair of nodes.

thanks
