Krell Institute Launches ‘Science in Parallel’ Podcast Focusing on Computational Science Innovators

AMES, IOWA – The Krell Institute is launching Science in Parallel, a podcast highlighting people and projects at the interface of science and computing. The first season features scientists who use computers to design alternative energy strategies, zero in on the chemistry of molecular surfaces, build quantum control algorithms and more. Along the way, listeners also will […]

Let’s Talk Exascale: Optimizing the North American Power Grid for Reliability and Decarbonization

In this episode of Let’s Talk Exascale from the Department of Energy’s Exascale Computing Project (ECP) the focus is on an ECP application development project called ExaSGD, shorthand for Optimizing Stochastic Grid Dynamics at Exascale. The word “stochastic” means results are given in terms of probabilities instead of exact predictions — weather forecasting may be […]

Let’s Talk Exascale Code Development: WDMAPP—XGC, GENE, GEM

This is episode 82 of the Let’s Talk Exascale podcast, provided by the Department of Energy’s Exascale Computing Project, exploring the expected impacts of exascale-class supercomputing. This is the third in a series on sharing best practices in preparing applications for the upcoming Aurora exascale supercomputer at the Argonne Leadership Computing Facility. The series highlights […]

Radio Free HPC:  Cerebras AI Computing at EPCC and HPE’s Chippewa Falls Remodel

We have a full crew for this wide-ranging episode of RFHPC. We start with a discussion of the new Cerebras and HPE-based supercomputer slated for the Edinburgh Parallel Computing Center in, well, Edinburgh. We talk some feeds-and-speeds for the new boxes, particularly about the 400,000-core wafer Cerebras box, along with some of the workloads that will be […]

Radio Free HPC – Big Changes at Intel: Gelsinger Takes the Helm

Our main topic today is Intel, with the bulk of the discussion surrounding the return of Pat Gelsinger as Intel’s new CEO. Pat was a 30-year veteran of Intel before he left to pursue other, well, pursuits – most notably as CEO of VMware. While at Intel, Pat spearheaded the development of the 486 architecture […]

Radio Free HPC: Digital D-Day – SolarWinds Hack

Our main topic for this episode is the SolarWinds hack. This is the worst digital hacking incident to date and will have repercussions for many years. As many as 18,000 SolarWinds’ customers may have downloaded the hacked update and opened themselves up to digital mayhem and thievery. This includes many government accounts, some of the […]

Radio Free HPC: High Performance Christmas Episode

After a late fall hiatus, Radio Free HPC is back, baby. This is our holiday episode and we start by pledging to be 29 percent more scintillating in the new year, which is a significant bonus for listeners if we can hit that mark. The theme of the show is HPC:  High Performance Christmas. We […]

‘Let’s Talk Exascale’: How Supercomputing Is Shaking Up Earthquake Science

Supercomputing is bringing seismic change to earthquake science. A field that historically has predicted by looking back now is moving forward with HPC and physics-based models to comprehensively simulate the earthquake process, end to end. In this episode of the “Let’s Talk Exascale” podcast series from the U.S. Department of Energy’s Exascale Computing Project (ECP), David McCallen, leader of ECP’s Earthquake Sim (EQSIM) subproject, discusses his team’s work to help improve the design of more quake-resilient buildings and bridges.

‘Let’s Talk Exascale’: Storing and Managing Exa-class Data Volumes

In this new edition of “Let’s Talk Exascale” from the Department of Energy’s Exascale Computing Project, the ECP’s Scott Gibson talks with Jim Ahrens of Los Alamos National Laboratory about the project’s data and visualization portfolio. As Ahrens said in this interview, “We can compute much faster than we can save and store data these […]

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 […]
