Benchmarking and Designing for Energy Efficiency: How to Break a World Record in 30 Days
Energy efficiency is a key concern in contexts ranging from large-scale data centers to mobile devices. This talk discusses our work on benchmarking and designing data-
intensive systems for energy efficiency. After mentioning the pitfalls surrounding the creation of JouleSort, a whole-system, energy-based benchmark, the talk will describe the
100GB JouleSort system that can sort 11,300 records for a Joule --- the 2007 world record. Also discussed will be the results and insights from measuring the efficiency of a
variety of systems from desktops to embedded devices. Going beyond JouleSort, there are preliminary results characterizing the efficiency of audit-class TPC-H systems,
which suggest that in the future software optimizations will play an important role in reducing energy-use. It is to be hoped that the audience will be armed with the tools and
know-how to break an energy-efficiency world record in fewer than 30 days.
