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...

February 1, 2012 — LLNL: Scientists help define structure of exoplanets

Exoplanets
The planet GJ 1214b, shown here in an artist's conception with two hypothetical moons, orbits a "red dwarf" star 40 light-years away from Earth.

LIVERMORE, Calif. -- Using models similar to those used in weapons research, scientists may soon know more about exoplanets, those objects beyond the realm of our solar system.

In a new study, Lawrence Livermore National Laboratory scientists and collaborators came up with new methods for deriving and testing the equation of state (EOS) of matter in exoplanets and figured out the mass-radius and mass-pressure relations for materials relevant to planetary interiors...more
