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…

Learning With the Flow

The bigger the swirl, the bigger the problem — and the bigger the computing power needed to solve it. Computational fluid dynamics researchers have spent decades studying how liquids and gases flow in and around such machinery as airplane wings, propeller blades and jet engines in search of faster speeds…

Putting Quantum Circuits to the Test

Researchers used Oak Ridge National Laboratory’s Quantum Computing User Program, or QCUP, to perform the first independent comparison test of leading quantum computers. The study surveyed 24 quantum processors and ranked results from each against performance numbers touted by such vendors as IBM, Rigetti and Quantinuum (formerly Honeywell). The research…

Autocoding Cancer

An algorithm developed by the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL) in partnership with the National Cancer Institute (NCI) is speeding up classification, or coding, of cancer pathology reports. The early results from the Cancer Moonshot program show that the algorithm dramatically reduces the time it…

The Climate in a Container

Successfully running a simulation program on a supercomputer requires more than just writing code. An application such as a climate model requires libraries, network support, and the correct operating environment. Because of these complex and multilayered requirements, applications are typically customized and built natively on a computing system, making them…

Exascale Acceleration

Just how fast can the world’s fastest supercomputer go? Maybe even faster than imagined. Researchers studying plasma physics for particle accelerators recently used the Oak Ridge Leadership Computing Facility’s Frontier supercomputer to achieve a speedup by as much as eightfold in their code’s performance – more than double the improvement…

Distilling How Water Turns into Ice

Among the mysteries of science that continue to elude researchers, one stands apart in its vexing simplicity: ice. Yes, frozen water. Water’s transformation from liquid to solid is actually a complex process of nature that scientists have named—nucleation—yet do not fully understand. However, Princeton University researchers have taken trailblazing steps…

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…
