Frontier and the Oak Ridge Team are Celebrating Exascale Day
October 18, 2023 by
Exascale computing is transforming our ability to solve some of the world’s most difficult and important problems. On October 18, the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL) is celebrating the fifth National Exascale Day. The holiday was created in 2019 as an initiative of DOE’s Exascale Computing Project (ECP) and Cray, […]
Exascale Day 2023: The Exascale Computing Era Is Here.
October 18, 2023 by
With the delivery of the U.S. Department of Energy’s (DOE’s) first exascale system, Frontier, in 2022, and the upcoming deployment of Aurora and El Capitan systems by next year, researchers will have the most sophisticated computational tools at their disposal to conduct groundbreaking research. Exascale machines can perform more than a billion billion calculations per […]
Building a Capable Computing Ecosystem for Exascale
September 18, 2023 by
With ECP, working together was a prerequisite for participation. “From the beginning, the teams had this so-called ‘shared fate,’” says Siegel. When incorporating new capabilities, applications teams had to consider relevant software tools developed by others that could help meet their performance targets, and if they didn’t choose to use them….
EXAALT-ing Molecular Dynamics to the Power of Exascale
June 21, 2023 by
As part of the Exascale Computing Project (ECP), a collaborative team of scientists, software developers, and hardware integration specialists from across the Department of Energy (DOE) has developed the Exascale Atomistics for Accuracy, Length, and Time (EXAALT) application to bring molecular dynamics (MD) into the exascale era. Danny Perez, a physicist within the Theoretical Division at Los Alamos National Laboratory and the project’s principal investigator says, “We’ve implemented new scalable methods that allow us to access as much of the accuracy, length and time space as possible on exascale machines by rethinking our methods and developing algorithms that go around some of the bottlenecks that limited scaling previously.” Such a capability has potential to revolutionize MD.
