Early science runs prepare Sequoia for national security missions

NNSA’s Sequoia supercomputer, housed at Lawrence Livermore National Laboratory, is ready to shake out and fully develop its capabilities required to fulfill its national security missions, starting early next year.
Researchers from NNSA's three nuclear weapons laboratories are testing Sequoia's power and versatility by running unclassified science codes relevant to NNSA missions. Science being explored by Lawrence Livermore researchers includes high energy density plasmas and the electronic structure of heavy metals.
The early science runs are part of the "shakeout" of the 20-petaflop peak IBM BlueGene/Q system, which will transition in March 2013 to classified work for NNSA's Advanced Simulation and Computing program, a cornerstone of the effort to ensure the safety, security and effectiveness of the nation's nuclear deterrent without underground testing. Sequoia's mammoth computational power will be used to assess physical weapons systems and provide a more accurate atomic-level understanding of the behavior of materials in the extreme conditions present in a nuclear weapon.
