Interesting, but depressing, presentation. At HotInterconnects in 2011, Intel gave a presentation about the reductions in power per flop over time. The corresponding communication power consumption per bit was flat (no improvement). Projecting the trends forward and with a 20 Mw power budget, an exascale machine's network would consume all the power leaving nothing for computation.
