Sierra or ATS-2 is a supercomputer built for the Lawrence Livermore National Laboratory for use by the National Nuclear Security Administration as the second Advanced Technology System.

The IBM-built Sierra supercomputer is providing over six times the sustained throughput performance and over five times the sustained scalable science performance of Sequoia, with a 125 petaflops peak.

Built by IBM in partnership with NVIDIA Corporation and Mellanox Technologies, Sierra is a heterogeneous supercomputer that uses IBM Power9 central processing units (CPUs) and NVIDIA Tesla V100 Tensor Core graphics processing units (GPUs).

Lawrence Livermore National Laboratory’s (LLNL) next-generation supercomputer, Sierra, is the third-fastest computing system in the world, according to the TOP500 list announced today at the International Supercomputing Conference in Frankfurt, Germany.

The Department of Energy’s National Nuclear Security Administration (NNSA), Lawrence Livermore National Laboratory (LLNL) and its industry partners today officially unveiled Sierra, one of the world’s fastest supercomputers, at a dedication ceremony to celebrate the …

Sierra is a classified, 125 petaflop, IBM Power Systems AC922 hybrid architecture system comprised of IBM POWER9 nodes with NVIDIA Volta GPUs. Sierra is a Tri-lab resource sited at Lawrence Livermore National Laboratory.

2017年11月20日 · Through the Sierra Center of Excellence, Livermore Lab code developers and computer scientists have been collaborating with on-site IBM and NVIDIA employees to port applications. The LLNL team also is working closely with IBM to install the system at the same time IBM and Oak Ridge National Laboratory are installing the Summit system there.

Sierra’s advanced heterogeneous, or hybrid, architecture uses more than one type of processor or core. It combines 17,280 NVIDIA Tesla V100 (volta) graphics processing units (GPUs), which increase parallel processing power, and 8,640 IBM Power9 central processing units (CPUs).
