The Green500: Trends for Energy-Efficient Supercomputing

Authors: Dr. Wu Feng (Virginia Polytechnic Institute and State University)

BP Abstract: With power a first-order design constraint on par with performance, it is important to measure and analyze trends for energy-efficient supercomputing. This BOF will discuss trends across the Green500 and highlights from the latest Green500 list. The Green500 and TOP500, in collaboration with the Energy-Efficient HPC WG, have a newly integrated submission process designed to streamline future submissions and to provide a consistent set of data for the historical record. It will also provide a forum for community review of the integrated submission process. The BOF will close with an awards presentation, recognizing the most energy-efficient supercomputers in the world.

Long Description: To raise the awareness of greenness as a first-order design constraint, the Green500 seeks to characterize the energy efficiency of supercomputers. Based on this characterization, it also provides a ranking of the most energy-efficient supercomputers in the world. The goals of this BoF are multi-fold: (1) analyze and announce the latest Green500 List, (2) present technical details and analysis on three of the most energy-efficient supercomputers, (3) describe the newly integrated submission process and solicit community feedback, and (4) present case studies on improving quality and accuracy aspects of the power measurement methodology. This joint BoF between the Green500, Top500, and the Energy Efficient HPC Working Group (EE HPC WG) has been held every year at SC since SC11. The participation has varied between 100 and 125 people. Feedback on the newly integrated submission process in particular as well as feedback on the power measurement methodology more generally will be captured and published in a report by the EE HPC WG. This information will be used to make submission process and methodology improvements. The Green500 List will be published on the Green500 website. All other presentations (technical details on the three most energy efficient supercomputers as well as case studies on power measurement methodology) will also be published on the Green500 website.
