Energy-efficient computing and the announcement of the Green500 list were at the center of attention yesterday, 20 November, at the SC13 conference in Denver.
Since 2007 the HPC community has not only been interested in raw performance of supercomputers but also in energy efficiency, contributing their part to the overarching and politically important discussion on reducing energy consumption. Precise definition and measurement of energy efficiency is still a controversial topic, but the data presented in the Top500 list on Monday already indicated that Piz Daint, the Cray XC30 system installed at CSCS, would be among the “greenest” petaflop supercomputers in the world.
This was confirmed yesterday when Piz Daint was named the 4th most energy efficient supercomputer and ranked #1 among all petaflop supercomputers.
CSCS Director Thomas Schulthess participated in the birds-of-a-feather meeting on power and efficiency measurement and there received a certificate acknowledging that Piz Daint was the most energy efficient petaflop supercomputers worldwide.
