Exascale’s New Frontier: Combustion-Pele

PI: Jacqueline Chen, Sandia National Laboratories 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 meant rethinking, reinventing, and optimizing dozens of scientific applications and software…

Watch: ‘The Journey to Frontier’ Mini-Doc

The job of designing and building the world's first supercomputer capable of exascale speed — running at least a quintillion calculations per second — was no simple task. It took over 10 years of planning and advances in chip technology to culminate in the construction of the Frontier supercomputer at…

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…

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…

Solving the Protein Puzzle

A simple scoop of soil or water can hold an entire ecosystem–potentially millions or more microscopic organisms and the countless proteins they rely on to survive. Computations performed at the U.S. Department of Energy’s Oak Ridge National Laboratory could help count, sort and catalog each of those proteins in record…
