In this episode of the Let’s Talk Exascale podcast, produced by DOE’s Exascale Computing Project, the topic is an ECP subproject called QMCPACK, which aims to find, predict, and control materials from first principles with predictive accuracy. This episode offers a conversation with QMCPACK’s principle investigator, Paul Kent, a distinguished R&D staff member at Oak Ridge National Laboratory. The discussion
ORNL Director Zacharia to Retire
July 14, 2022 by
Dr. Thomas Zacharia announced his retiremnt as director of Oak Ridge National Laboratory at the end of 2022, the culmination of a 35-year career at the science and energy laboratory. The news follows another significant upper management change at the lab last month — the retirement of Dr. Jeff A. Nichols as associate laboratory director […]
Exascale Computing Project Supports Atmospheric Convection Modeling
July 5, 2022 by
July 5, 2022 – Researchers supported by the US Department of Energy’s (DOE’s) Exascale Computing Project (ECP) have integrated the super-parameterization technique for modeling moist convection into the Energy Exascale Earth System Model (E3SM), which is a global climate modeling, simulation, and prediction project being developed by DOE. This method is designed to enable E3SM to improve […]

Lawrence Berkeley’s Marques to Run Exascale Computing Project’s Training & Productivity Effort
April 26, 2022 by
April 26, 2022 — Osni Marques, a staff scientist in the Applied Math and Computational Research Division at Lawrence Berkeley National Laboratory (Berkeley Lab), has been tapped to lead the Training & Productivity (T&P) effort within the US Department of Energy’s Exascale Computing Project. He takes over for Ashley Barker of Oak Ridge National Laboratory. Marques has been […]
ExaIO: Access and Manage Storage of Data Efficiently and at Scale on Exascale Systems
April 19, 2022 by
As the word exascale implies, the forthcoming generation exascale supercomputer systems will deliver 1018 flop/s of scalable computing capability. All that computing capability will be for naught if the storage hardware and I/O software stack cannot meet the storage needs of applications running at scale—leaving applications either to drown in data when attempting to write to storage or starve while waiting to read data from storage. Suren Byna, PI of the ExaIO project in the Exascale Computing Project (ECP) and computer staff scientist at Lawrence Berkeley National Laboratory, highlights the need for preparation to address the I/O needs of exascale supercomputers by noting that storage is typically the last subsystem available for testing on these systems.
Exascale Computing Project Releases New Version of Extreme-Scale HPC Scientific Software Stack
March 31, 2022 by
The Extreme-scale Scientific Software Stack (E4S) high-performance computing (HPC) software ecosystem—an ongoing broad collection of software capabilities continually developed to address emerging scientific needs for the US Department of Energy community—recently released version 22.02. E4S, which began in the fall of 2018, is aimed at accelerating the development, deployment, and use of HPC software, thereby […]
Oak Ridge: Frontier Exascale to Deliver ‘Full User Operations’ on Jan. 1, 2023; ‘Crusher’ Test System Now Running Code
March 28, 2022 by
“Crusher,” a partial form of the planned 100+-cabinet Frontier supercomputer at the U.S. Department of Energy’s Oak Ridge National Laboratory, is now running principal scientific codes at the Oak Ridge Leadership Computing Facility. The Crusher test system is comprised of 1.5 cabinets powered by 3rd Gen AMD EPYC CPUs and AMD Instinct MI250x GPU accelerators. […]
Exascale: Preparing PETSc/TAO Software for Scientific Applications
March 10, 2022 by
In this episode of the Let’s Talk Exascale podcast, produced by DOE’s Exascale Computing Project, the topic is PETSc—the Portable, Extensible Toolkit for Scientific Computation. It’s a suite of data structures and routines for the scalable (parallel) solution of scientific applications modeled by partial differential equations. A team within ECP is preparing PETSc/TAO for exascale […]
