Big Flex for Big Science

Researchers used the world’s first exascale supercomputer to run one of the largest simulations of an alloy ever and achieve near-quantum accuracy. The study led by the University of Michigan’s Vikram Gavini employed Frontier, the 1.14-exaflop HPE Cray EX supercomputer at the Department of Energy’s Oak Ridge National Laboratory, to…

ORNL Researchers Develop Open-Source Mixed-Precision Benchmark Tool

As Frontier, the world’s first exascale supercomputer, was being assembled at the Oak Ridge Leadership Computing Facility in 2021, understanding its performance on mixed-precision calculations remained a difficult prospect. That gap in understanding wasn’t an oversight but rather a sign of just how novel supercomputer systems that excel at mixed…

Exascale Drives Industry Innovation for a Better Future

By Caryn Meissner, ECP contributing writer   Outside the high-performance computing, or HPC, community, exascale may seem more like fodder for science fiction than a powerful tool for scientific research. Yet, when seen through the lens of real-world applications, exascale computing goes from ethereal concept to tangible reality with exceptional…

Exascale’s New Frontier: WDMApp

PI: Amitava Bhattacharjee Princeton Plasma Physics Laboratory In 2016, the US Department of Energy’s (DOE’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 meant rethinking, reinventing, and optimizing dozens of scientific…

Predicting the Future of Fission Power

As renewable sources of energy such as wind and sun power are being increasingly added to the country’s electrical grid, old-fashioned nuclear energy is also being primed for a resurgence. For the past 20 years, fission reactors have produced a nearly unchanging portion of the nation’s electricity: around 20%. But…
