摘 要：Technology scaling trends have enabled the exponential growth of computing power. How-ever, the performance of communication subsystems scales less aggressively. This means thatan application constrained by memory/interconnect performance will not be able to use theavailable computing power e?ciently—in fact, technology scaling will make this e?ciency even worse.
