Despite the move away from very high-frequency, high-ILP cores to multiple, more modest cores ("multicore"), power is still a huge, unsolved problem for the microprocessor industry. The emphasis is no longer power-aware processor microarchitecture but power-aware systems architecture. The "system" extends from the multicore system-on-chip to the external memory, disks, indeed to the entire enterprise. The data center has arisen as a major target of power-related computer architecture research. The greater question is, in our attempts to make the world's information available to all in the blink of an eye, what is the environmental cost, and how can we as a research community address this problem?
