WASHINGTON, D.C. –National Nuclear Security Administration (NNSA) Administrator Thomas D'Agostino congratulates the Advanced Simulation and Computing program for two supercomputers ranked in the TOP Green500's top 10 most energy-efficient supercomputers in the world as of November 2009.
The two computers in the top 10 are housed at Los Alamos National Laboratory: Cerrillos (#4) and Roadrunner (#9). Six other supercomputers housed at NNSA sites were also ranked in the TOP Green500 list.
Additionally, three of the top six supercomputers on the list are based on NNSA's Roadrunner system. Fifteen of the top 23 supercomputers on the list are based on NNSA and Department of Energy's Office of Science co-investments in Blue Gene/P technology.
"Energy efficiency is one of NNSA's top priorities as we transform from a Cold War nuclear weapons complex into a 21st century nuclear security enterprise," said NNSA Administrator Thomas D'Agostino. "I am proud of the work done by our supercomputer engineers and scientists. I applaud our enterprise-wide commitment to being effective stewards of taxpayer dollars while promoting energy awareness."
The purpose of the Green500 is to provide a ranking of the most energy-efficient supercomputers in the world. For decades, the notion of performance has been synonymous with speed. This particular focus has led to the emergence of supercomputers that consume large amounts of electrical power and produce heat that requires extravagant cooling facilities to ensure proper operation. The Green500 list encourages supercomputing stakeholders to create systems that are both cutting-edge and energy efficient.
Roadrunner currently runs open science and engineering simulations including a simulation aiding HIV vaccine design. Cerrillos is a Roadrunner-like system with 162TF which recently has been installed at LANL to allow unclassified research.
Last week NNSA congratulated its national laboratories and supercomputing program for earning three of the top 10 spots on the latest TOP500 supercomputer list. The top 10 included Roadrunner (#2, Los Alamos National Laboratory); BlueGene/L (#7, Lawrence Livermore National Laboratory); and Red Sky (#10, Sandia National Laboratories/National Renewable Energy Laboratory). In addition, the Dawn platform at Livermore was ranked as the 11th fastest in the world. A total of eight supercomputers housed at NNSA labs made the TOP500 list.
Recently, President Barack Obama presented the National Medal of Technology and Innovation, the nation's most prestigious honor for innovators in technological achievement, to the Blue Gene series of computers, an IBM product line brought to market through investments by the NNSA and the Department of Energy.

Established by Congress in 2000, NNSA is a semi-autonomous agency within the U.S. Department of Energy responsible for enhancing national security through the military application of nuclear science in the nation's national security enterprise. NNSA maintains and enhances the safety, security, reliability, and performance of the U.S. nuclear weapons stockpile without nuclear testing; reduces the global danger from weapons of mass destruction; provides the U.S. Navy with safe and effective nuclear propulsion; and responds to nuclear and radiological emergencies in the U.S. and abroad.
