@HPCpodcast: An Analysis of the New Top500 List

In this episode of @HPCpodcast, sponsored by Lenovo, Shahin and Doug discuss the big news on the Monday of each annual ISC conference in Germany, the release of the new Top500 ranking of the world’s most powerful supercomputers. At ISC 2024 here in Hamburg, we learned that the U.S. now has two exascale-class systems, , the AMD/HPE-Cray Frontier system at Oak Ridge National Laboratory and ….

INCITE Call for Proposals for Access to Leadership-Class Supercomputers Open through June 14

The U.S. Department of Energy’s Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program is now accepting proposals for high-impact, computationally intensive research projects in a broad array of science, engineering and computer science domains. Proposals must be submitted between April 10 and June 14, 2024. Open to researchers from academia, industry and […]

@HPCpodcast: Matt Sieger of OLCF-6 on the Post-Exascale ‘Discovery’ Vision

What does a supercomputer center do when it’s operating two systems among the TOP-10 most powerful in the world — one of them the first system to cross the exascale milestone? It starts planning its successor.  The center is Oak Ridge National Lab, a U.S. Department….

Exascale’s New Software Frontier: ExaSGD

“Exascale’s New Frontier,” a project from the Oak Ridge Leadership Computing Facility, explores the new applications and software technology for driving scientific discoveries in the exascale era. The Scientific Challenge As more renewable sources of energy are added to the national power grid, it becomes more complex to manage. That’s because renewables such as wind […]

HPC News Bytes Podcast 20230807: PCIe over Optical, Quantum at Oak Ridge, Domain-Specific Architectures, Intel Expands Oregon Fabs

Kicking off the week with a fast (4:17) review of the latest HPC news: McKinsey reported on the rise of domain-specific architectures that quantifies the slowdown of Moore’s Law and lists five DSA-boosting trends; Intel’s plans for a massive, billions-dollars-plus expansion of chip fabs in Oregon; PCI-SIG’s new workgroup to deliver PCIe technology over optical connections; Oak Ridge National Lab scientists used a Quantinuum quantum computer to produce “an intriguing scientific result” in solar cell research.

Oak Ridge Scientists Use Quantum Computer for Solar Cell Research

Oak Ridge National Laboratory has announced that researchers at the lab used the Quantinuum H1-1 quantum computer to not only demonstrated best practices for scientific computing on current quantum systems but also produced what the lab said is an intriguing scientific result. The project was funded by DOE’s Office of Basic Energy Sciences. Access to […]

OLCF and Stony Brook: Using HPC Simulations to Learn How Cicada Wings Kill Bacteria

Over the past decade, teams of engineers, chemists and biologists have analyzed the physical and chemical properties of cicada wings, hoping to unlock the secret of their ability to kill microbes on contact. If this function of nature can be replicated by science, it may lead to products with inherently antibacterial surfaces that are more […]

LLNL’s Lori Diachin Named Director of Exascale Computing Project

Lawrence Livermore National Laboratory’s Lori Diachin will take over as director of the Department of Energy’s Exascale Computing Project on June 1, “guiding the successful, multi-institutional high-performance computing effort through its final stages,” ECP said in its announcement. Diachin, who is currently the principal deputy associate director for LLNL’s Computing Directorate, has served as ECP’s […]

@HPCpodcast: For Lower Costs and Carbon, Liquid Cooling’s Growing HPC Presence

Gone are the days when liquid cooling for HPC-class servers (and, for that matter, other types of servers and PCs) is thought of as risky. In fact, liquid cooling has been under development for decades — it goes back much farther than you might think. And now that the power required to cool HPC clusters and data centers has become so expensive and carbon-intensive, liquid cooling has become increasingly prevalent. Some HPC centers report liquid cooling has cut their electrical spending by more than 30 percent. These and related topics are the focus of this @HPCpodcast episode, sponsored by Lenovo. Shahin and Doug discuss liquid cooling as part of decarbonization and sustainability strategies. We cover everything from chilled doors to direct-to-chip, immersion cooling, vapor chambers, under-water data centers

OLCF’s Paul Abston Named Data Center Manager of the Year

Paul Abston, leader of the HPC Infrastructure Operations Group of the National Center for Computational Sciences and manager of the Oak Ridge Leadership Computing Facility’s data center, has been named Data Center Manager of the Year for 2023. The award, sponsored by Data Center World, the global conference for data center facilities and IT professionals, recognizes […]
