A supermassive black hole called Sagittarius A* (yes, the asterisk is part of it!) sits at the center of the Milky Way. Now, for the first time, we can see it. The resulting direct image of Sagittarius A*, revealed this week, was made possible by the Event Horizon Telescope (EHT) array and the Frontera supercomputer […]

The federal government is uniquely positioned to leverage massive amounts of data to transform everything from how it operates to supporting mission-critical services and advancing vital research. Artificial Intelligence (AI) is key to that transformation, helping to drive new developments in cybersecurity, healthcare, life sciences, platform sustainment, humanitarian response, and disaster relief. Today, government agencies […]

Berkeley Lab Researchers Synthesize New Ultrathin Capacitor

October 24th, 2022 |
Electron microscope images show the precise atom-by-atom structure of a barium titanate (BaTiO3) thin film sandwiched between layers of strontium ruthenate (SrRuO3) metal to make a tiny capacitor.

The silicon-based computer chips that power our modern devices require vast amounts of energy to operate. Despite ever-improving computing efficiency, information technology is projected to consume around 25% of all primary energy produced by 2030. Researchers in the microelectronics and materials sciences communities are seeking ways to sustainably manage the global need for computing power. […]

University of Chicago physicists have invented a “quantum flute” that, like the Pied Piper, can coerce particles of light to move together in a way that’s never been seen before. The post UChicago Scientists Invent ‘Quantum Flute’ appeared first on HPCwire.

The Final Frontier: US Has Its First Exascale Supercomputer

October 14th, 2022 |

In April 2018, the U.S. Department of Energy announced plans to procure a trio of exascale supercomputers at a total cost of up to $1.8 billion dollars. Over the ensuing four years, many announcements were made, many deadlines were missed, and a pandemic threw the world into disarray. Now, at long last, HPE and Oak […]

Streaming HPC: An Emerging Model for Delivering HPC Capability?

high-performance-computing jobs

The HPC sector is on the cusp of yet another change in the way it does business, except this time the pendulum is swinging away from HPC vendors having the upper hand in choosing the products they deliver towards HPC users who define their workloads and then assemble the vendor-agnostic hardware and software they need […]

What’s So Great About Quantum Computing? A Q&A with NIST Theorist Alexey Gorshkov

October 11th, 2022 |
Alexey Gorshkov

National Institute of Standards and Technology (NIST) public affairs specialist Chad Boutin interviewed Alexey Gorshkov, a NIST theorist at NIST/University of Maryland’s Joint Center for Quantum Information and Computer Science (QuICS) and Joint Quantum Institute, who works at the intersection of physics and computer science research. His efforts are helping in the design of quantum […]

TACC Supercomputer Tackles El Niño Variability

October 4th, 2022 |
earth weather patterns from space

The El Niño climate pattern, when it occurs, presents as warmer-than-usual water in the equatorial region of the Pacific Ocean. The changes in temperature and rainfall that ensue from this warmer water can affect natural disasters, crop yields and even the proliferation of disease — but El Niño’s variations can be hard to predict. Recently, […]

Physicists Work To Shrink Microchips with First One-Dimensional Helium Model System

October 3rd, 2022 |

Microchips are everywhere, running computers and cars, and even helping people find lost pets. As microchips grow smaller, faster and capable of doing more things, the wires that conduct electricity to them must follow suit. But there’s a physical limit to how small they can become—unless they are designed differently. The post Physicists Work To […]
