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…

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…

Charting the New Frontier

The Frontier supercomputer at the U.S. Department of Energy’s Oak Ridge National Laboratory logged a new benchmark this week that further illustrates its world-changing potential and held onto its top ranking as the world’s fastest on the 60th TOP500 list. Frontier set a new speed record for the mixed-precision calculations often used by artificial…

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…

WarpX Named Gordon Bell Prize Finalist

The development of plasma-based particle accelerators—experimental technology that promises several advantages over conventional accelerators—may soon be accelerated itself by a new, advanced simulation code: WarpX. Produced primarily by a team of researchers at Lawrence Berkeley National Laboratory (Berkeley Lab), Lawrence Livermore National Laboratory, and the French Alternative Energies and Atomic…
