As cloud and utility computing spreads, computer architects must ensure continued capability growth for the data centers that comprise the cloud. Given megawatt scale power budgets, increasing data center capability requires increasing computing hardware energy efficiency. To increase the data center's capability for work, the work done per Joule must increase. The authors pursue this efficiency even as the nature of data center applications evolves. Unlike traditional enterprise workloads, which are typically memory or I/O bound, big data computation and analytics exhibit greater compute intensity.
