A research collaboration between the Department of Energy’s Oak Ridge National Laboratory and several partner institutions was honored with the Best Event Report award at the 2024 International Conference on Game Jams, Hackathons and Game Creation Events. The eighth annual conference for researchers, educators, professionals and event organizers in high-performance…

New Data Transfer Tool Developed at ORNL to Be Made Available for Public Use
Jake Wynne, an HPC storage systems engineer at ORNL, created the hsi_xfer tool to simplify the process of transferring large quantities of data. A new data transfer tool created at the Oak Ridge Leadership Computing Facility could be available to facilities nationwide after making its debut at the Department of…

Bigger, Faster, Smarter Genetics Research
A team of researchers used the Frontier supercomputer at the Department of Energy’s Oak Ridge National Laboratory and a new methodology for conducting a genome-wide association study, or GWAS, to earn a finalist nomination for the Association for Computing Machinery’s 2024 Gordon Bell Prize for outstanding achievement in high-performance computing,…

Goodbye HPSS, Hello Kronos
Users of the Oak Ridge Leadership Computing Facility are experiencing big changes with how their data is stored — in a good way. As the OLCF’s High Performance Storage System is to be decommissioned in early 2025 after decades of service, users are becoming familiar with Kronos, which is already proving its ease of use and…

Standing up the Nation’s Supercomputing Pipeline for Streaming Big Data in Real Time
Big science generates big data. But what happens when researchers produce more data than they can process? It’s actually becoming a problem for research facilities that generate so much data that only supercomputers can tackle the volume. To bridge the gap between experimental facilities and supercomputers, experts from SLAC National…

Exascale’s New Frontier: CANDLE
PI: Rick Stevens Associate Laboratory Director, Computing, Environment and Life Sciences, Argonne National Laboratory In 2016, the Department of Energy’s Exascale Computing Project (ECP) set out to develop advanced software for the arrival of exascale-class supercomputers capable of a quintillion (1018) or more calculations per second. That leap meant rethinking,…

Exascale’s New Frontier: ExaWind
PI: Michael Sprague, National Renewable Energy Laboratory In 2016, the Department of Energy’s (DOE’s) Exascale Computing Project (ECP) set out to prepare advanced software for the arrival of exascale-class supercomputers capable of 1 quintillion or more calculations per second. That meant rethinking, reinventing and optimizing dozens of scientific applications and…

Exascale’s New Frontier: ADIOS
PI: Scott Klasky, Oak Ridge National Laboratory In 2016, the Department of Energy’s Exascale Computing Project (ECP) set out to develop advanced software for the arrival of exascale-class supercomputers capable of a quintillion (1018) or more calculations per second. That leap meant rethinking, reinventing, and optimizing dozens of scientific applications…

Going Big: World’s Fastest Computer Takes On Large Language Modeling
A team led by researchers at the Department of Energy’s Oak Ridge National Laboratory explored training strategies for one of the largest artificial intelligence models to date with help from the world’s fastest supercomputer. The findings could help guide training for a new generation of AI models for scientific research.…

Breaking Benchmarks: Frontier Supercomputer Sets New Standard in Molecular Simulation
When scientists pushed the world’s fastest supercomputer to its limits, they found those limits stretched beyond even their biggest expectations. The Frontier supercomputer at the Department of Energy’s Oak Ridge National Laboratory set a new ceiling in performance when it debuted in 2022 as the first exascale system in history…

Something in the Water Does Not Compute
Computational scientists at the Department of Energy’s Oak Ridge National Laboratory have published a study in the Journal of Chemical Theory and Computation that questions a long-accepted factor in simulating the molecular dynamics of water: the 2 femtosecond (one quadrillionth of a second) time step. The femtosecond is a timescale…

ORNL and SLAC Team Up for Breakthrough Biology Projects
Plans to unite the capabilities of two cutting-edge technological facilities funded by the Department of Energy’s Office of Science promise to usher in a new era of dynamic structural biology. Through DOE’s Integrated Research Infrastructure, or IRI, initiative, the facilities will complement each other’s technologies in the pursuit of science…

Adaptable IO System Delivers the Data
Amid the challenges that the Department of Energy’s Oak Ridge Leadership Computing Facility faced in assembling and launching the world’s first exascale-class (more than a quintillion calculations per second) supercomputer, Frontier, one key component was hitch-free. Integral to Frontier’s functionality is its ability to store the vast amounts of data…

Steering Toward Quantum Simulation at Scale
Researchers simulated a key quantum state at one of the largest scales reported, with support from the Quantum Computing User Program, or QCUP, at the Department of Energy’s Oak Ridge National Laboratory. The techniques used by the team could help develop quantum simulation capabilities for the next generation of quantum…
