Top-Ranked Supercomputers at Livermore Computing Center

Sierra

Sierra, Livermore’s latest advanced technology high performance computing system, joined LLNL’s lineup of supercomputers in 2018. The new system provides computational resources that are essential for nuclear weapon scientists to fulfill the National Nuclear Security Administration’s stockpile stewardship mission through simulation in lieu of underground testing. Advanced Simulation and Computing (ASC) Program scientists and engineers use Sierra to assess the performance of nuclear weapon systems as well as nuclear weapon science and engineering calculations. These calculations are necessary to understand key issues of physics, the knowledge of which later makes its way into the integrated design codes. This work on Sierra has important implications for other global and national challenges such as nonproliferation and counterterrorism.

Lassen

Lassen, an unclassified, heterogeneous IBM/NVIDIA system with the same architecture as Sierra but smaller, placed No. 10 on the June 2019 Top500 list with a High Performance Linpack (HPL) benchmark score of 18.2 petaFLOPS (18.2 quadrillion point operations per second) boosting its original 15.4 petaFLOP performance from the previous November.

Magma

Magma is a Penguin Computing “Relion” system comprised of 752 nodes with Intel Xeon Platinum 9242 (Cascade Lake-AP) processors. The cluster has 293 terabytes of memory, liquid cooling provided by CoolIT Systems and an Intel Omni-Path interconnect. Its 3.24 Linpack petaflops placed it 69th on the latest Top500 list of the world’s most powerful supercomputers out of a theoretical peak of 5.31 petaflops. On a per-node basis, the Cascade Lake processors deliver about three to three and a half times the performance compared to Broadwell processors deployed earlier in the CTS program.

More about Magma

A flagship facility in the Advanced Simulation and Computing Program, Livermore Computing houses some of the world's fastest supercomputers accessible to ~3000 researchers.

Computing advances the frontiers of computational science and delivers game-changing solutions to society’s biggest challenges in energy, environment, and national and global security. Our research and development activities are applications driven and are focused on LLNL programmatic objectives.
