NNSA's Sequoia supercomputer ranked as world's fastest

Supercomputer at Lawrence Livermore National Lab passes 16 petaflops

WASHINGTON, D.C. - The National Nuclear Security Administration (NNSA) today announced that a supercomputer called Sequoia at Lawrence Livermore National Laboratory (LLNL) was ranked the world's most powerful computing system. Clocking in at 16.32 sustained petaflops (quadrillion floating point operations per second), Sequoia earned the No. 1 ranking on the industry standard Top500 list of the world's fastest supercomputers released Monday, June 18, at the International Supercomputing Conference (ISC12) in Hamburg, Germany. Sequoia was built for NNSA by IBM.

A 96-rack IBM Blue Gene/Q system, Sequoia will enable simulations that explore phenomena at a level of detail never before possible. Sequoia is dedicated to NNSA's Advanced Simulation and Computing (ASC) program for stewardship of the nation's nuclear weapons stockpile, a joint effort from LLNL, Los Alamos National Laboratory and Sandia National Laboratories.

"Computing platforms like Sequoia help the United States keep its nuclear stockpile safe, secure and effective without the need for underground testing," NNSA Administrator Thomas D'Agostino said. "While Sequoia may be the fastest, the underlying computing capabilities it provides give us increased confidence in the nation's nuclear deterrent as the weapons stockpile changes under treaty agreements, a critical part of President Obama's nuclear security agenda. Sequoia also represents continued American leadership in high performance computing, key to the technology innovation that drives high-quality jobs and economic prosperity."
