Frontier Simulations Could Help Build a Better Diamond

The world’s fastest supercomputer helped researchers simulate synthesizing a material harder and tougher than diamond — or any other substance on Earth. The study used Frontier, the HPE Cray EX supercomputing system at the Department of Energy’s Oak Ridge National Laboratory, to predict the likeliest strategy to synthesize such a…

Untangling the Entangled

Researchers used quantum simulations to obtain new insights into the nature of neutrinos — the mysterious subatomic particles that abound throughout the universe — and their role in the deaths of massive stars. The study relied on support from the Quantum Computing User Program, or QCUP, and the Quantum Science Center, a national Quantum Information…

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…

Oxygen-28 Unbound

Isotopes — atoms of a particular element that have different numbers of neutrons — can be used for a variety of tasks, from tracking climate change to conducting medical research. Investigating rare isotopes, which have extreme neutron-to-proton imbalances and are often created in accelerator facilities, provides scientists with opportunities to…

Peering into the Universe’s Dark Matter

A research team from the University of California, Santa Cruz, have used the Oak Ridge Leadership Computing Facility’s Summit supercomputer to run one of the most complete cosmological models yet to probe the properties of dark matter — the hypothetical cosmic web of the universe that largely remains a mystery…

Reaching a New Summit for Supernova Simulations

As a result of largescale 3D supernova simulations conducted on the Oak Ridge Leadership Computing Facility’s Summit supercomputer by researchers from the University of Tennessee and Oak Ridge National Laboratory, astrophysicists now have the most complete picture yet of what gravitational waves from exploding stars look like. This is critical…

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…

New Geometric Model Improves Predictions of Fluid Flow in Rock

Deep beneath the Earth’s surface, oil and groundwater percolate through gaps in rock and other geologic material. Hidden from sight, these critical resources pose a significant challenge for scientists seeking to evaluate the state of such two-phase fluid flows. Fortunately, the combination of supercomputing and synchrotron-based imaging techniques enables more…

Summit Speeds Calculations in the Search for Exotic Particles

In pursuit of numerical predictions for exotic particles, researchers are simulating atom-building quark and gluon particles over 70 times faster on Summit, the world’s most powerful scientific supercomputer, than on its predecessor Titan at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL). The interactions of quarks and…
