Lab breaks ground for exascale facility upgrades

To meet the needs of tomorrow’s supercomputers, NNSA's LLNL has broken ground on its ECFM project, which will substantially upgrade the mechanical and electrical capabilities of the Livermore Computing Center.

Cooling Magma is a Challenge that LLNL Can Take On

With 5.4 petaflops of peak performance crammed into 760 compute nodes, that is a lot of computing capability in a small space generating a considerable amount of heat.

Sierra

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 supercomputer

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.

Quartz supercomputer

Jade and Quartz

Jade and Quartz are identically configured Penguin Computing systems. They each have 2,688 nodes and 343 TB of memory and a peak speed of 3.2 pflops. Each system is a 14 Scalable Unit multiprocessor cluster with Intel Broadwell processors. Jade and Quartz are 97 and 98 on the November 2019 Top500 list.

Magma supercomputer

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.
