Oak Ridge Lab and Veterans Affairs Use Summit Supercomputer Security Framework for Health Research

Dec. 1, 2022 — A team from Oak Ridge National Laboratory (ORNL) and the US Department of Veterans Affairs (VA) used the CITADEL security framework to securely transfer and analyze veterans’ health records on ORNL’s Summit, an IBM AC922 supercomputer housed at the Oak Ridge Leadership Computing Facility, a US Department of Energy (DOE) Office […]

Scientists Using Frontier Supercomputer Win 2022 Gordon Bell Prize, Another Frontier Team Named Prize Finalist

[SPONSORED CONTENT]   How many researchers can say they’ve not only run their scientific job on the AMD-powered Frontier supercomputer, the world’s no. 1 ranked HPC system and the first exascale-class machine, but also on Fugaku, Summit and Perlmutter, the world’s second-, fifh- and eighth-ranked HPC systems in the world, respectively? But that’s the case with an interntional group of researchers working on particle-in-cell simulations who have developed code that won….

Research Team Uses Summit to Earn Gordon Bell Prize Nomination for Simulating Carbon in Extreme Conditions

A research team used machine-learned descriptions of interatomic interactions on the 200-petaflop Summit supercomputer at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL) to model more than a billion carbon atoms at quantum accuracy and observe how diamonds behave under some of the most extreme pressures and temperatures imaginable. The team was led by scientists […]

ORNL Study on COVID-19 Earns Gordon Bell Prize Nomination

As the coronavirus pandemic entered its second year, a team of scientists from the U.S. Department of Energy’s Oak Ridge National Laboratory used the nation’s fastest supercomputer to streamline the search for potential treatments. “The approach we used to search for promising molecules resembles natural selection in fast forward,” said Andrew Blanchard, one of the […]

Toolkit Delivers 4D Visualization, Addresses Data Volume Challenges in Exascale

The Exascale Computing Project (ECP) has announced that a team of researchers has developed the Feature Tracking Kit (FTK), which uses simplicial spacetime meshing to simplify, scale, and deliver novel feature-tracking algorithms for in situ data analysis and scientific visualization. FTK delivers feature-tracking tools, scales feature-tracking algorithms in distributed and parallel environments, and simplifies development […]

ORNL Researchers, Summit HPC Support IPCC Climate Change Report

As part of the Next-Generation Ecosystem Experiments Arctic project, scientists are gathering and incorporating new data about the Alaskan tundra into global models that predict the future of our planet.

Summit Supercomputer Helps Crack Code to Signature Superconductor ‘Kink’

May 19, 2021 — Scientists have long been trying to understand the behavior of superconductors, materials that have zero electrical resistance when they reach sufficiently low temperatures. Superconductors might be useful for technologies such as magnets for MRIs, fusion devices, and particle accelerators. To understand superconductors, one concept is pivotal: phonons, which are quantum waves […]

Summit and Theta Supercomputers Power ML Models for Fusion Energy Research

A team led by C.S. Chang at Princeton Plasma Physics Laboratory (PPPL) has used the Oak Ridge Leadership Computing Facility’s (OLCF’s) 200-petaflop Summit and Argonne Leadership Computing Facility’s (ALCF’s) 11.7-petaflop Theta supercomputers, together with a supervised machine learning program called Eureqa, to find….

ORNL Offers Virtual Tour of Summit’s Supercomputer Center

Oak Ridge National Lab has released a virtual tour of the facility that houses Summit, the world’s second most power supercomputer. The tour is offered by the National Center for Computational Sciences (NCCS) and the Oak Ridge Leadership Computing Facility (OLCF). They’re giving access to Building 5600 on the Oak Ridge campus where resides Summit, […]

Supercomputing the San Andreas Fault with CyberShake

With help from DOE supercomputers, a USC-led team expands models of the fault system beneath its feet, aiming to predict its outbursts. For their 2020 INCITE work, SCEC scientists and programmers will have access to 500,000 node hours on Argonne’s Theta supercomputer, delivering as much as 11.69 petaflops. “The team is using Theta “mostly for dynamic earthquake ruptures,” Goulet says. “That is using physics-based models to simulate and understand details of the earthquake as it ruptures along a fault, including how the rupture speed and the stress along the fault plane changes.”
