Yanpei Chen & Laura Keys: Energy Efficient Hadoop

There are compelling economic reasons to run datacenters with energy efficient software, as UC Berkeley researchers Laura Keys and Yanpei Chen describe in this talk. Typically, datacenters are measured using a Power Utilization Efficiency (PUE) metric-- but until now the role of software in the equation has been neglected.

The speakers include energy use as a dimension of software performance alongside productivity and resource consumption metrics, and describe their experiments and findings on changing Hadoop software parameters to improve energy efficiency.
