The Whole World Is Watching: ORNL’s Bernholdt & Programming Environment Team Prepare for Frontier and Exascale

The world’s fastest supercomputer comes with some assembly required. Frontier, the nation’s first exascale computing system, won’t come together as a whole until all pieces arrive at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory to be installed—with the eyes of the world watching—on the data center floor inside the Oak Ridge Leadership Computing Facility (OLCF). Once those components operate in harmony as advertised, David Bernholdt and his team can take time for a quick bow—and then get back to work.

How DOE Scientists Disrupted COVID-19

In early 2020, when the novel coronavirus was gaining momentum but had not yet been named a pandemic, computational chemist Marti Head of Oak Ridge National Laboratory – along with scientists and researchers around the globe – abruptly switched her focus to the fight against COVID-19. The world was struggling to understand this new virus known as severe acute […]

ORNL Names Innovation Crossroads Cohort of Manufacturing, Building and Clean Energy Technology Entrepreneurs

Six science and technology innovators from across the United States will join the fifth cohort of Oak Ridge National Laboratory’s Innovation Crossroads program in June. The southeast’s only research and development program for entrepreneurs based at a U.S. Department of Energy national laboratory, Innovation Crossroads provides support to science-based startups to help advance game-changing technologies […]

ORNL’s Gina Accawi: Designing Software for Manufacturing Cybersecurity

May 27, 2021 — As a computer engineer at Oak Ridge National Laboratory, Gina Accawi has long been the quiet and steady force behind some of the Department of Energy’s most widely used online tools and applications. She has written the code that industry throughout the United States relies on – from MEASUR, the platform […]

OLCF Releases Storage Specs for Frontier Exascale

A newly enhanced I/O subsystem will support the nation’s first exascale supercomputer, the HPE Cray Frontier system, and the Oak Ridge Leadership Computing Facility (OLCF). The computational might of exascale computing, expected to have top speeds of 1 quintillion — that’s 1018, or a billion billion — calculations per second, promises to enable breakthrough discoveries across the scientific spectrum when Frontier, set to power up by year’s end, opens to full user operations in 2022, from the basics of building better nuclear reactors to insights into the origins of the universe. The I/O subsystem will consist of two major components: an in-system storage layer and a center-wide file system. The center-wide file system, called Orion, will use open-source Lustre and ZFS technologies.

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 […]

HPE Supercomputer Installed at Oak Ridge for U.S. Air Force

HPE has delivered a two-systems-in-one supercomputer to support weather modeling and forecasting for the U.S. Air force and Army. The HPC system, powered by two HPE Cray EX supercomputers, is now operational at Oak Ridge National Laboratory, where it is managed by ORNL. HPE said that at 7.2 petaflops peak performance, the combined systems are […]

ORNL Now Accepting Abstracts for SMC 2021

The Department of Energy’s Oak Ridge National Laboratory is now accepting abstracts for the 2021 Smoky Mountains Computational Sciences and Engineering Conference (SMC 2021), a premier event for discussing the latest developments in computational sciences and engineering for high-performance computing (HPC) and integrated instruments for science. Specifically, ORNL is seeking revolutionary and visionary ideas in […]

Exascale Computing Project: Researchers Accelerate I/O with Novel Processing Method

January 25, 2021 — Researchers funded by the Exascale Computing Project (ECP) have delivered a novel method that addresses overloaded communication processes that use MPI-IO by adding a second I/O request aggregation layer, according to ECP. Their method, called TAM for two-phase aggregation method, combines data on a node prior to performing additional internode optimizations […]

Update from the Frontier of Exascale Software Development

In advance of the scheduled shipment this year of the U.S.’s first exascale supercomputer, Frontier, at Oak Ridge National Laboratory, an international team of software developers led by a University of Delaware professor is working on a plasma physics application. An article published yesterday in the university’s UDaily by Tracey Bryant details the work underway […]
