Exascale’s New Frontier: SuperLU/STRUMPACK

PI: Sherry Li, Lawrence Berkeley National Laboratory  In 2016, the Department of Energy’s Exascale Computing Project (ECP) set out to develop advanced software for the arrival of exascale-class supercomputers capable of a quintillion (1018) or more calculations per second. That leap meant rethinking, reinventing, and optimizing dozens of scientific applications…

New Clues to Improving Fusion Confinement

Nuclear fusion — when two nuclei combine to form a new nucleus, thereby releasing energy — may be the clean, reliable, limitless power source of the future. But first, scientists must learn how to control its production. Building on decades of prior research, scientists have developed sophisticated techniques to improve…

Closing In on Fusion

The same process that fuels stars could one day be used to generate massive amounts of power here on Earth. Nuclear fusion—in which atomic nuclei fuse to form heavier nuclei and release energy in the process—promises to be a long-term, sustainable, and safe form of energy. But scientists are still trying to fine-tune the process of…

Team Earns Gordon Bell Prize Finalist Nomination for Simulating Carbon at Extreme Pressures and Temperatures

Are diamonds even stronger than we’ve ever imagined? Can other post-diamond phases appear when diamond is subjected to extreme pressures? A team used machine-learned descriptions of interatomic interactions on the 200-petaflop Summit supercomputer at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL) to model more than a…

Weighing up Plasma Particles

The sun’s energy is the result of a continuous series of nuclear fusion reactions in which ionized hydrogen in the form of plasma collides at high speeds and releases helium and energetic neutrons—producing enormous bursts of energy in the process. For years, researchers have sought a way to harness this…

Speeding Toward the Future of Fusion

In 1934, physicist Ernest Rutherford and his colleagues produced the first fusion reaction—the fusing of light nuclei to release energy—in a laboratory by converting deuterium, a heavy hydrogen isotope, to helium. Since then, scientists have built increasingly efficient fusion energy devices with a goal to achieve net fusion energy, or…

How Hot Is Too Hot in Fusion?

Fusion, the energy that powers the stars, might one day provide abundant energy here on Earth. In a nuclear fusion reactor, the hot, charged gas known as plasma reaches out of this world temperatures at 150 million degrees Celsius, or 10 times hotter than the center of the sun. The…

Experts Converge on ORNL for US-Japan Fusion Workshop

For nearly 40 years the United States and Japan have collaborated on making the dream of limitless clean energy a reality. In 1980 the two countries created the US-Japan Joint Institute for Fusion Theory (JIFT) to formalize this collaboration. Since that time researchers from both countries have organized workshops to…
