Exascale’s New Frontier: LatticeQCD

PI: Andreas Kronfeld, Distinguished Scientist, Fermilab 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 leap meant rethinking, reinventing, and optimizing dozens of scientific applications and…

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…

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…

Where Worlds Collide

Lawrence Berkeley National Laboratory physicists Christian Bauer, Marat Freytsis, and Benjamin Nachman have leveraged an IBM Q quantum computer through the Oak Ridge Leadership Computing Facility’s (OLCF's) Quantum Computing User Program (QCUP) to capture part of a calculation of two protons colliding. The calculation can show the probability that an…

Getting a Big Look at Tiny Particles

At the turn of the 20th century, scientists discovered that atoms were composed of smaller particles. They found that inside each atom, negatively charged electrons orbit a nucleus made of positively charged protons and neutral particles called neutrons. This discovery led to research into atomic nuclei and subatomic particles. An…

With Supercomputing Power and an Unconventional Strategy, Scientists Solve a Next-Generation Physics Problem

Using the Titan supercomputer at the Oak Ridge Leadership Computing Facility (OLCF), a team of researchers has calculated a fundamental property of protons and neutrons, known as the nucleon axial coupling, with groundbreaking precision. Led by André Walker-Loud of the US Department of Energy’s (DOE’s) Lawrence Berkeley National Laboratory, the…
