Meet OLCF’s Gina Tourassi, Director of National Center for Computational Sciences

Since Gina Tourassi began her career, computer science has come a long way. Tourassi learned programming in the 1980s starting with QBasic. It’s a programming environment that hasn’t been included with Microsoft operating systems for more than 20 years. When she first discovered her love of computational research, computer scientists were programming artificial intelligence (AI) […]

OLCF’S HPC Systems Engineer Bing Xie Wins IEEE Early Career Award

Bing Xie, a high-performance computing systems engineer for the Oak Ridge Leadership Computing Facility, has received the Institute of Electrical and Electronics Engineers Computer Society’s Early Career Researchers Award for excellence in high-performance computing, or HPC. The award recognizes outstanding, influential and potentially long-lasting HPC contributions. Xie received her Ph.D. in computer science from Duke University […]

A Look Inside the US’s 1st Exascale Supercomputer Facility

Preparing for the nation’s first exascale system, the upcoming HPE Cray EX Frontier “Frontier” system at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL), has been a colossal undertaking. Since the spring of 2020, ORNL staff members have made numerous modifications to the building and room that will house Frontier, a system that will […]

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 […]

DOE Resumes Webinar Series Aug. 4 on HPC Scientific Software Engineering Challenges and Best Practices

The IDEAS Productivity project, in partnership with the DOE Computing Facilities of the ALCF, OLCF, and NERSC and the DOE Exascale Computing Project (ECP) has resumed the webinar series on Best Practices for HPC Software Developers, which began in 2016. To register for the event, go here. As part of this series, one-hour webinars are offered on topics in scientific […]

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 […]

Annual OLCF User Meeting Set for June 22–24

The Oak Ridge Leadership Computing Facility (OLCF), a US Department of Energy Office of Science user facility at Oak Ridge National Laboratory, will hold its 17th annual user meeting June 22–24, 2021. The meeting will take place entirely online due to the COVID-19 pandemic. Registration and agenda can be found here. Attendees will be offered […]

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 […]
