Abstract :
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?
