M5 models ethernet connections between machines, so if you want to model a cluster-type system you're in good shape (though we just have point-to-point links, so you'd need to write an ethernet switch model, but that shouldn't be too hard).
My previous email was referring to on-chip networks, where you're presumably connecting CPUs and caches within a single system.
