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 […]

Building an Exascale-Class Data Center for ORNL’s Incoming Frontier Supercomputer

Oak Ridge National Laboratory issued the following today, an update by staff science writer Coury Turczyn, on progress made in the construction of a data center capable of supporting ORNL’s Frontier exascale system, scheduled for installation next year. When the US Department of Energy’s (DOE’s) new exascale supercomputer, Frontier, completes installation at Oak Ridge National Laboratory […]

OpenACC Names ORNL’s Jack Wells President, Updates OpenACC API

Jack Wells, director of strategic planning and performance management at Oak Ridge National Laboratory, has been named president of OpenACC, a nonprofit dedicated to advancing scientists’ parallel computing skills. OpenACC also announced updates to Version 3.1 of OpenACC API for writing parallel programs in C, C++, and Fortran, and it announced the 2021 schedule of […]

Quantum Science: ORNL Researchers Talk about Exploring ‘Subatomic Weirdness’

Check out Oak Ridge National Lab’s latest Sounds of Science podcast in which ORNL researchers discuss what they hope to accomplish with quantum computing. As ORNL states in its introduction to this episode: “Quantum mechanics. Does the term alone make your brain hurt a little? If so, you’re not alone. It’s a very complex branch […]

DOE Under Secretary for Science Dabbar’s Exascale Update: Frontier to Be First, Aurora to Be Monitored

As Exascale Day (October 18) approaches, U.S. Department of Energy Under Secretary for Science Paul Dabbar has commented on the hottest exascale question of the day: which of the country’s first three systems will be stood up first? In a recent, far-reaching interview with us, Dabbar confirmed what has been expected for more than two months, that the first U.S. exascale system will not, as planned, be the Intel-powered Aurora system at Argonne National Laboratory. It will instead be HPE-Cray’s Frontier, powered by AMD CPUs and GPUs and designated for Oak Ridge National Laboratory.

The Hyperion-insideHPC Interviews: ORNL Distinguished Scientist Travis Humble on Coupling Classical and Quantum Computing

Oak Ridge National Lab’s Travis Humble has worked at the headwaters of quantum computing research for years. In this interview, he talks about his particular areas of interest, including integration of quantum computing with classical HPC systems.  “We’ve already recognized that we can accelerate solving scientific applications using quantum computers,” he says. “These demonstrations are just early examples of how we expect quantum computers can take us to the most challenging problems for scientific discovery.”

Let’s Talk Exascale Podcast – ECP Leadership Discuss Project Highlights, Challenges, Impact

The U.S. Department of Energy’s  Exascale Computing Project (ECP) is tasked with guiding the U.S. effort to build a “capable exascale ecosystem” by the early to mid-2020s and is part of the Exascale Computing Initiative, a partnership between DOE’s Office of Science and the National Nuclear Security Administration. In this podcast, members of ECP’s leadership […]
