In cases where I've used OpenMPI it was spanning machines as well as being multiple processes on the same box. The goal was making that interchangeable (in my use case). I imagine google's compute engine isn't all on separate machines, but utilizes VMs heavily.. although it's probably a bad idea to put one customer's VM's on all the same box. That's a long way of saying "of course you're right, I guess my thought doesn't contribute as much as I thought" :)
