Outside the high-performance computing, or HPC, community, exascale may seem more like fodder for science fiction than a powerful tool for scientific research.
Lawrence Livermore National Laboratory’s Lori Diachin will take over as director of the Department of Energy’s Exascale Computing Project on June 1, guiding the successful, multi-institutional high-performance computing effort through its final stages.
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 nearly three decades, scientists and engineers across the globe have worked on the Square Kilometre Array (SKA), a project focused on designing and building the world’s largest radio telescope.
On May 7, the US Department of Energy (DOE) announced the Frontier exascale supercomputer is slated for delivery in 2021 at DOE’s 91°µÍø (ORNL).
In a step toward advancing small modular nuclear reactor designs, scientists at 91°µÍø have run reactor simulations on ORNL supercomputer Summit with greater-than-expected computational efficiency.
David Bernholdt is a Distinguished R&D Staff Member and Group Leader at 91°µÍø (ORNL).
Improving the Ability to Accurately Predict the Operating Behavior of Small Modular Nuclear Reactors
Steven Hamilton is an R&D staff member in the Reactor & Nuclear Systems Division at 91°µÍø.
When scientists discovered the immense power contained in an atom, the United States government provided the laboratories, factories, and funding necessary to harness that power and end World War II.
Nuclear scientists at 91°µÍø are retooling existing software used to simulate radiation transport in small modular reactors, or SMRs, to run more efficiently on next-generation supercomputers.
