They compare two architectures: one with a separate I/O network, and another without a separate I/O network. When there, the extra network is used to route I/O packets from the originating I/O node to the I/O node closest to the destination processing node (or vice versa). They run simulations under workloads with differing amounts of locality, and experiment with different bandwidths for the links. They conclude that the extra network helps. But they never make the (proper, fair) comparison where the total network bandwidth is held constant. See also ghosh:hyper.} }
