Energy efficiency of supercomputers has become a major challenge over the past years. For over 6 years, the Green500 ranks the world's fastest supercomputers by their energy efficiency. "Measuring energy efficiency means measuring supercomputer performance and power consumption at the same time. While the benchmarks for measuring performance are well established and performance results in FLOPs (Floating Point Operations Per Second) are easy to compare among different machines, the methodology for measuring power consumption was missing a commonly accepted standard in recent years", comments Prof. Arndt Bode, managing director of the Leibniz Supercomputing Centre of the Bavarian Academy of Sciences jlo Uuaxudmzmr.
