Ensuring the nation’s electrical power grid can function with limited disruptions in the event of a natural disaster, catastrophic weather or a manmade attack is a key national security challenge. Compounding the challenge of grid management is the increasing amount of renewable energy sources such as solar and wind that are continually added to the […]

OLCF and Stony Brook: Using HPC Simulations to Learn How Cicada Wings Kill Bacteria
July 14, 2023 by
Over the past decade, teams of engineers, chemists and biologists have analyzed the physical and chemical properties of cicada wings, hoping to unlock the secret of their ability to kill microbes on contact. If this function of nature can be replicated by science, it may lead to products with inherently antibacterial surfaces that are more […]
EXAALT-ing Molecular Dynamics to the Power of Exascale
June 21, 2023 by
As part of the Exascale Computing Project (ECP), a collaborative team of scientists, software developers, and hardware integration specialists from across the Department of Energy (DOE) has developed the Exascale Atomistics for Accuracy, Length, and Time (EXAALT) application to bring molecular dynamics (MD) into the exascale era. Danny Perez, a physicist within the Theoretical Division at Los Alamos National Laboratory and the project’s principal investigator says, “We’ve implemented new scalable methods that allow us to access as much of the accuracy, length and time space as possible on exascale machines by rethinking our methods and developing algorithms that go around some of the bottlenecks that limited scaling previously.” Such a capability has potential to revolutionize MD.
Outgoing Exascale Computing Project Director Doug Kothe Takes on New Role at Sandia Labs
June 16, 2023 by
Doug Kothe knows about transitions, including transitions on a grand scale. The outgoing director of the U.S. Department of Energy’s Exascale Computing Project helped transition the supercomputing industry into the exascale era. He took the ECP helm in October 2017, and in May 2022, the project reached a milestone with the certification of the Frontier […]
