BlueGene/L Supercomputer, LLNL, 2000s


BlueGene/L on the TOP500 list of supercomputers with a sustained world-record speed of teraFLOPS - is a revolutionary, low-cost machine delivering extraordinary computing power for the nation's Stockpile Stewardship Program. Located in the Terascale Simulation Facility at Lawrence Livermore National Laboratory, BlueGene/L is used by scientists at Livermore, Los Alamos, and Sandia National Laboratories. The 596-teraFLOPS machine handles many challenging scientific simulations, including ab initio molecular dynamics; three-dimensional (3D) dislocation dynamics; and turbulence, shock, and instability phenomena in hydrodynamics. It is also a computational science research machine for evaluating advanced computer architectures. From 2004 through 2007 the Blue Gene/L installation at LLNL gradually expanded to 104 racks, achieving 478 TFLOPS Linpack and 596 TFLOPS peak. The LLNL BlueGene/L installation held the first position in the TOP500 list for years, until in June 2008 it was overtaken by IBM's Cell-based Roadrunner system at Los Alamos National Laboratory, which was the first system to surpass the 1 PetaFLOPS mark.
