On October 26, 2018, the Department of Energy’s National Nuclear Security Administration (NNSA), Lawrence Livermore National Laboratory (LLNL) and its industry partners officially unveiled Sierra, one of the world’s fastest supercomputers, at a dedication ceremony to celebrate the system’s completion.
Sierra will serve the NNSA’s three nuclear security laboratories, LLNL, Sandia National Laboratories and Los Alamos National Laboratory, providing high-fidelity simulations in support of NNSA’s core mission of ensuring the safety, security and effectiveness of the nation’s nuclear stockpile. Its arrival represents years of procurement, design, code development and installation, requiring the efforts of hundreds of computer scientists, developers and operations personnel working in close partnership with IBM, NVIDIA and Mellanox.
