Expanded BlueGene/L supercomputer sets new mark and retains rank as world’s fastest machine

The National Nuclear Security Administration’s BlueGene/L retained its number one ranking on the new Top500 list of the world’s fastest supercomputers, released today at the international Supercomputing 2007 conference in Reno, Nevada.

Housed in Lawrence Livermore National Laboratory’s Terascale Simulation Facility, BlueGene/L (BGL) clocked 478.2 trillion floating operations per second (teraFLOPS) on LINPACK, the industry standard of measure for high-performance computing. Built by IBM, BGL is a workhorse supercomputer used to make possible science simulation of unprecedented detail for NNSA’s tri-lab Advanced Simulation and Computing (ASC) Program, which leverages the computing expertise and resources of Sandia, Los Alamos and Lawrence Livermore national laboratories.
