Sudden Changes at Ultra-High Pressure
Livermore physicist Jon Belof and a team of physicists, engineers, and computational scientists are subjecting matter to extreme conditions and simulating experiments with high-performance computers to study phase transitions at ultrahigh pressures.
Exascale in motion on earthquake risks
Assessing large magnitude (greater than 6 on the Richter scale) earthquake hazards on a regional (up to 100 kilometers) scale takes big machines. To resolve the frequencies important to engineering analysis of the built environment (up to 10 Hz or higher), numerical simulations of earthquake motions must be done on today's most powerful computers.
A quicker picker upper? Lab researchers eye papermaking improvements through HPC
Paper-making research, performed for an HPC4Manufacturing (HPC4Mfg) project with the papermaking giant, Proctor and Gamble, resulted in the largest multi-scale model of paper products to date, simulating thousands of fibers in ParaDyn with resolution down to the micron scale.
Transforming electrical grid resiliency with distributed energy resources
Normally, in a large-scale emergency, distributed energy resources (DERs) -- such as the energy produced by solar panels at customers' homes -- are shut off to protect the greater electrical grid. But a new project headed by Lawrence Livermore National Laboratory (LLNL) aims to utilize these resources for restoration and recovery operations, boosting the grid's ability to bounce back from a blackout or cascading outage, and potentially reducing customer reconnection time to a matter of hours.
Metamaterials: Using Supercomputers to Mold Electromagnetics
Sandia researchers modeled the electromagnetics of complex systems on two DOE supercomputers that can solve tens of millions of problems in hours: Trinity (LANL) and Sequoia (LLNL). This research has led to impressive advances in metamaterials research that will boost the substances’ flexibility, efficiency, adaptability and other properties.
DOE's HPC4Mfg seeks industry proposals to advance energy tech
The U.S. Department of Energy's High Performance Computing for Manufacturing Program, designed to spur the use of national lab supercomputing resources and expertise to advance innovation in energy efficient manufacturing, is seeking a new round of proposals from industry to compete for $3 million.
Accelerating Simulation Software with Graphics Processing Units
To address the challenges of transitioning to the next generation of high performance computing (HPC), Livermore is bringing together designers of hardware, software, and applications to rethink and redesign their HPC elements and interactions for the exascale era (i.e., systems capable of a billion billion floating point operations per second or 1018 flops).
Preparing for Sierra, LLNL's next state-of-the-art supercomputer
In late 2017, IBM will begin delivery of Sierra, the latest in a series of leading-edge Advanced Simulation and Computing (ASC) Program supercomputers. Delivering peak speeds of up to 150 petaflops (1015 floating-point operations per second), Sierra is projected to provide at least four to six times the performance of Sequoia, Livermore’s current flagship supercomputer. To run efficiently on Sierra, applications must be modified to achieve a level of task division and coordination well beyond what previous systems demanded.
Computational innovation boosts manufacturing
The DOE's High Performance Computing for Manufacturing (HPC4Mfg) Program aims to advance clean-energy technologies, increase the efficiency of manufacturing processes, accelerate innovation, reduce the time it takes to bring new technologies to market, and improve the quality of products. The program unites the world-class high-performance computing (HPC) resources and expertise of Lawrence Livermore and other national laboratories with U.S. manufacturers to deliver solutions that could revolutionize the manufacturing industry.
Two LLNL CTS-1 cluster systems named to TOP100 supercomputer list
Two Penguin Computing systems installed at Lawrence Livermore National Laboratory, Quartz and Jade, were ranked 41st and 42nd on the TOP100 list of the world's fastest supercomputers. The announcement came during the SC16 supercomputing conference, held November 13–18, 2016, in Salt Lake City, Utah. The systems were procured under NNSA’s Tri-Laboratory Commodity Technology Systems program, or CTS-1, to bolster computing for national security at Los Alamos, Sandia, and Lawrence Livermore national laboratories.
High-Performance Computing Takes Aim at Cancer
A historic partnership between the Department of Energy (DOE) and the National Cancer Institute (NCI) is applying the formidable computing resources at Livermore and other DOE national laboratories to advance cancer research and treatment. The effort will help researchers and physicians better understand the complexity of cancer, choose the best treatment options for every patient, and reveal possible patterns hidden in vast patient and experimental data sets.
LLNL team’s molecular dynamics code among Gordon Bell Prize finalists
A Lawrence Livermore team's dramatically improved first-principles molecular dynamics code that promises to enable new computer simulation applications was one of the finalists for the 2016 Gordon Bell Prize. The team presented its ground-breaking project at the 2016 supercomputing conference (SC16) held in Salt Lake City, Utah, November 12-18, 2016. "Modeling Dilute Solutions using First-Principles Molecular Dynamics: Computing more than a Million Atoms with over a Million Cores," was the title of the Livermore team's submission for the competition. Using a robust new algorithm, the Livermore team has developed an O(N)complexity solver for electronic structure problems with fully controllable numerical error.
Lawrence Livermore to lead "co-design" center for exascale computing ecosystem
Lawrence Livermore National Laboratory (LLNL) was one of four national labs selected to lead a "co-design" center by the Department of Energy's Exascale Computing Project (link is external) (ECP) as part of a four-year, $48 million funding award. Each co-design center will receive $3 million annually. LLNL's Tzanio Kolev is the director of the newly established ECP co-design Center for Efficient Exascale Discretizations (CEED). "Co-design" refers to the collaborative and interdisciplinary engineering process for developing capable exascale systems.
Scientists selected to lead Exascale Computing Project software development
Lawrence Livermore scientists are among those who have been awarded funding to develop software for the Department of Energy's Exascale Computing Project (link is external) (ECP). The ECP selected 35 software development proposals representing 25 research and academic organizations; Livermore computer scientists will lead six of the projects and are collaborators on another seven. The awards, totaling $34 million for the first year of funding, cover many components of the software stack for exascale systems.
DOE HPC4Mfg Program to help jumpstart clean energy technologies
A U.S. Department of Energy (DOE) program designed to spur the use of high performance supercomputers to advance U.S. manufacturing has funded 13 new industry projects for a total of $3.8 million. Experts at Lawrence Livermore and other DOE national laboratories will work directly with manufacturing industry members to teach them how to adopt or advance their use of high performance computing (HPC) to address manufacturing challenges with a goal of increasing energy efficiency, reducing environmental impacts, and advancing clean energy technologies.
