‘Unify’ Delivers Fast I/O Performance over Distributed Storage

LNL’s Center for Applied Scientific Computing (CASC) and Livermore Computing divisions recently joined forces to tackle performance drag caused by input/output (I/O) workloads.

DOE Machines Dominate Record-Breaking SC18

At SC18, it was announced that for the first time in five years, the U.S. captured the top two spots on the TOP500 List of the world’s fastest supercomputers: LLNL's Sierra and ORNL's Summit.

Call for HPC for Energy Innovation proposals

DOE issued its first joint solicitation for the High Performance Computing for Manufacturing Program (HPC4Mfg) and the High Performance Computing for Materials Program (HPC4Mtls).

Top-Ranked Supercomputers at Livermore Computing Center

  • Sequoia
  • Catalyst
  • Vulcan
  • Sierra

Sequoia

Ranked among the world’s most powerful supercomputers, Sequoia supports two missions: quantify the uncertainties in numerical simulations of nuclear weapons performance and perform the advanced weapons science calculations needed to develop the accurate physics-based models for weapons codes. Sequoia is primarily water-cooled and significantly more energy efficient than comparable systems, which is essential to control operating costs.

Sequoia has been ranked in the top four on the Graph500 list since November 2012, indicating that it is one of the most efficient systems in the world for processing extremely vast (petabyte and exabyte-size) data sets. The Graph500 benchmark measures how quickly a system can search through a large data set—an important indicator of a system’s usefulness as computer scientists increasingly use supercomputers to analyze massive data-intensive workloads in addition to executing traditional modeling and simulation tasks.

Catalyst

The 150 teraFLOP/s Catalyst, a unique high-performance computing (HPC) cluster, serves as a proving ground for new HPC and big data technologies, architectures, and applications. Developed by a partnership of Cray, Intel, and Lawrence Livermore, this Cray CS300 system is available for collaborative projects with industry through Livermore’s HPC Innovation Center. Catalyst also supports the LLNL’s Advanced Simulation and Computing program.

Catalyst features include 128 gigabytes of dynamic random access memory (DRAM) per node and 800 gigabytes of non-volatile memory (NVRAM) per compute node. The increased storage capacity of the system represents a major departure from classic simulation-based computing architectures common at Department of Energy laboratories and enables researchers to explore the potential of combining floating point-focused capability with data analysis in one environment.

Vulcan

A unique resources available through the High Performance Computing Innovation Center, Vulcan was part of the contract that brought Sequoia to Livermore. Industrial collaborators can access Vulcan's 1.5 of its 5 petaFLOPS as part of NNSA’s mission to enhance U.S. economic competitiveness.

Sierra

Our newest supercomputer, Sierra, is nearing completion and projected to provide four to six times the sustained performance and five to seven times the workload performance of Sequoia, with ~125 petaFLOP/s peak. The Collaboration of Oak Ridge, Argonne and Lawrence Livermore, also known as CORAL, represents an innovative procurement strategy to accelerate the development of high performance computing. Sierra is the Livermore system acquired as a result of the CORAL procurements, which will influence the modernization of future generations of computing throughout the NNSA complex.
