Lawrence Livermore National Laboratory (LLNL) and artificial intelligence computer company Cerebras Systems have integrated the world’s largest computer chip into the National Nuclear Security Administration’s (NNSA’s) Lassen system, upgrading the top-tier supercomputer with cutting-edge AI technology.
Hadrons are elusive superstars of the subatomic world, making up almost all visible matter, and British theoretical physicist Antoni Woss has worked diligently with colleagues at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility to get to know them better. Now, Woss’ doctoral thesis on spinning hadrons has earned him the 2019 Jefferson Science Associates Thesis Prize.
A series of simulations using multiple supercomputers, including Comet at the San Diego Supercomputer Center (SDSC) at UC San Diego, suggests that when the neutron stars’ masses are different enough, the result is far noisier. The models predicted an electromagnetic ‘bang,’ which isn't present when the merging stars' masses are similar, according to researchers.
Researchers at the University of Delaware have gained new understanding of the virus that causes hepatitis B and the “spiky ball” that encloses the virus’s genetic blueprint. They examined how the capsid—a protein shell that protects the blueprint and also drives the delivery of it to infect a host cell—assembles itself. Scientists believe that the capsid is an important target in developing drugs to treat hepatitis B, a life-threatening and incurable infection that afflicts more than 250 million people worldwide.
A Lawrence Livermore National Laboratory (LLNL) team has published new supercomputer simulations of a magnitude 7.0 earthquake on the Hayward Fault. This work represents the highest ever resolution ground motion simulations from such an event on this scale.
Virginia Institute of Marine Science (VIMS) researchers used supercomputer simulations to examine impacts of both regional and global changes affecting the Chesapeake Bay. They discovered that historical increases in fertilizers and atmospheric carbon dioxide concentrations have forced the bay to behave increasingly like a small sea on a continental shelf rather than a traditional estuary.
Researchers at the McKelvey School of Engineering at Washington University in St. Louis have developed a new algorithm for solving a common class of problem -- known as linear inverse problems -- by breaking them down into smaller tasks, each of which can be solved in parallel on standard computers.
Computational scientific research is no longer one-size-fits-all. The massive datasets created by today’s cutting-edge instruments and experiments — telescopes, particle accelerators, sensor networks and molecular simulations — aren’t best processed and analyzed by a single type of machine.
A team led by Dan Jacobson of the Department of Energy’s Oak Ridge National Laboratory used the Summit supercomputer at ORNL to analyze genes from cells in the lung fluid of nine COVID-19 patients compared with 40 control patients.
Groundbreaking simulation provides data that could help manufacturers create greener engines.
Scientists at the Department of Energy’s Oak Ridge National Laboratory used neutron scattering and supercomputing to better understand how an organic solvent and water work together to break down plant biomass, creating a pathway to significantly improve the production of renewable biofuels and bioproducts.
Researchers at the University of New Hampshire used SDSC's Comet supercomputer to validate a model using a machine learning technique called Dynamic Time Lag Regression (DTLR) to help predict the solar wind arrival near the Earth’s orbit from physical parameters of the Sun.
Geoscientists at The University of Texas at Dallas recently used supercomputers to analyze massive amounts of earthquake data to generate high-resolution, 3D images of the dynamic geological processes taking place far below the Earth’s surface.
A team used the Summit supercomputer to simulate transition metal systems—such as copper bound to molecules of nitrogen, dihydrogen, or water—and correctly predicted the amount of energy required to break apart dozens of molecular systems, paving the way for a greater understanding of these materials.
The NSF has awarded the San Diego Supercomputer Center (SDSC) at UC San Diego a $5 million grant to develop a high-performance resource for conducting artificial intelligence (AI) research across a wide swath of science and engineering domains.
Researchers have performed the first room temperature X-ray measurements on the SARS-CoV-2 main protease—the enzyme that enables the virus to reproduce. It marks an important first step in the ultimate goal of building a comprehensive 3D model of the enzymatic protein that will be used to advance supercomputing simulations aimed at finding drug inhibitors to block the virus’s replication mechanism and help end the COVID-19 pandemic.
Researchers from Harvard University and the University of Texas Medical Branch at Galveston recently used the Comet supercomputer at the San Diego Supercomputer Center (SDSC) at the University of California San Diego to uncover the novel ways in which DNA prepares itself for repair.
Researchers have demonstrated that an advanced computer code could help design stellarators confine the essential heat from plasma fusion more effectively.
The Sherlock Division of the San Diego Supercomputer Center (SDSC) at the University of California San Diego has broadened its secure Cloud solutions portfolio to offer Skylab, an innovative customer-owned Cloud platform solution that provides a self-standing, compliant environment for secure workloads in the Amazon Web Services (AWS) Cloud.
To meet the needs of tomorrow’s supercomputers, the National Nuclear Security Administration’s (NNSA’s) Lawrence Livermore National Laboratory (LLNL) has broken ground on its Exascale Computing Facility Modernization (ECFM) project, which will substantially upgrade the mechanical and electrical capabilities of the Livermore Computing Center.
