Energy Efficient High-Performance Computing Working Group: Power Measurement Methodology

About the document

You can only improve what you can measure, but that can be easier said than done. The Green500, Top500, Green Grid and Energy Efficient HPC Working Group are collaborating on specifying workloads, methodologies and metrics for measuring the energy efficiency of supercomputing systems for architecture design and procurement decision-making processes. A current focus on this collaboration is to improve the methodology for measuring energy in order to get an ‘apples to apples’ comparison between system architectures.

About the EEHPC WG

Demand for High Performance Computing (HPC) is growing in both the public and private sectors. It is also highly energy-intensive. The Federal government is required by the Energy Independence and Security Act of 2007 (EISA) to reduce energy intensity in all facilities, including laboratories and industrial buildings, by 30% by 2015. The increasing need for HPC and the attendant energy intensity threatens to derail the progress toward this and other goals. Through meeting mandated energy reductions, the Federal government is poised to lead by example in energy efficiency.

The HPC industry is responding to the demand for more powerful equipment, and consequently, creating increasingly energy intensive products. However, as profit-maximizing entities, businesses have a clear need for energy efficient computing due to the uncertainties in energy markets. The Energy Efficient HPC Working Group (EE HPC WG) will target both public and private HPC owners, operators and users to increase collective knowledge and stimulate demand for energy efficient HPC.
