RadioFreeHPC Podcast: New Top on the TOP500

We have a new #1 on the TOP500 list of most powerful supercomputers. Big gets bigger by a factor of 2.8x as Fujitsu’s “Supercomputer Fugaku” tops the list at 415 PFlops.  There are also an additional three new entries in the top 10. We break down the top of the list in this fascinating episode […]

Let’s Talk Exascale: Forecasting Water Resources and Severe Weather with Greater Confidence

In this episode of Let’s Talk Exascale, Mark Taylor of Sandia National Laboratories talks about using exascale supercomputers for severe weather and water resource forecasting. A sub-project within the US Department of Energy’s (DOE’s) Exascale Computing Project (ECP) called E3SM-MMF is working to improve the ability to simulate the water cycle and the processes around precipitation. Our guest on the latest episode of ECP’s podcast, Let’s Talk Exascale, is Mark Taylor of Sandia National Laboratories, principal investigator of the E3SM-MMF project.

Radio Free HPC Episodes ….In Case You Missed It

There are fresh episodes of Radio Free HPC out in the wild and, in case you missed them, here’s what’s new: ColdQuanta Serves Up Some Bose-Einstein Condensate May 7, 2020 The show starts with Dan, Jessi and Shahin in attendance. Henry is traveling from his old home base in Minnesota to his new command bunker […]

ExaAM Project Aims to Transform Additive Manufacturing through Exascale Simulation

In the latest episode of the Let’s Talk Exascale podcast, we are joined by John Turner of Oak Ridge National Laboratory. He is principal investigator of the ExaAM project within the US Department of Energy’s (DOE’s) Exascale Computing Project (ECP). ExaAM plans to transform AM through exascale computer simulations.

Podcast: Streamlined Data Science through Jupyter Lab and Jupyter Enterprise Gateway

“Jupyter is a free, open-source, interactive web tool known as a computational notebook, which researchers can use to combine software code, computational output, explanatory text and multimedia resources in a single document. This podcast looks at how the Bright Jupyter integration makes it easy for customers to use Bright for Data Science through JupyterLab notebooks, and allows users to run their notebooks through a supported HPC scheduler, Kubernetes, or on the server running JupyterHub.”

Podcast: A Shift to Modern C++ Programming Models

In this Code Together podcast, Alice Chan from Intel and Hal Finkel from Argonne National Lab discuss how the industry is uniting to address the need for programming portability and performance across diverse architectures, particularly important with the rise of data-intensive workloads like artificial intelligence and machine learning. “We discuss the important shift to modern C++ programming models, and how the cross-industry oneAPI initiative, and DPC++, bring much-needed portable performance to today’s developers.”

Slidecast: The Sad State of Affairs in HPC Storage (But there is light at the end of the tunnel)

In this video, Robert Murphy from Panasas describes the current state of the HPC storage market and how Panasas is stepping up with high performance products that deliver economical performance without risk. “According to a recent study published by Hyperion Research, total cost of ownership (TCO) now rivals performance as a top criterion for purchasing HPC storage systems. Newly retooled with COTS hardware and a unique architecture, Panasas delivers surprising performance at a lower TCO than competitive solutions.”

Podcast: ColdQuanta Serves Up Some Bose-Einstein Condensate

“ColdQuanta is headed by an old pal of ours Bo Ewald and has just come out of stealth mode into the glaring spotlight of RadioFreeHPC. When you freeze a gas of Bosons at low density to near zero you start to get macroscopic access to microscopic quantum mechanical effects, which is a pretty big deal. With the quantum mechanics start, you can control it, change it, and get computations out of it. The secret sauce for ColdQuanta is served cold, all the way down into the micro-kelvins and kept very locally, which makes it easier to get your condensate.”

Podcast: David Barkai book to chronicle the History of HPC

In this podcast, the Radio Free HPC team catches up with special guest today, David Barkai, a 50-year veteran of HPC. David has worked in a wide variety of positions at NASA, Intel, Cray, SGI and others. His current project is writing a book to chronicle the last 50 years in HPC told from the perspective of those who were there. “The main emphasis in the book is examining the good that HPC has done in the world, which is quite the story.”

Podcast: Spack Helps Automate Deployment of Supercomputer Software

In this Let’s Talk Exascale podcast, Todd Gamblin from LLNL describes how the Spack flexible package manager helps automate the deployment of software on supercomputer systems. “After many hours building software on Lawrence Livermore’s supercomputers, in 2013 Todd Gamblin created the first prototype of a package manager he named Spack (Supercomputer PACKage manager). The tool caught on, and development became a grassroots effort as colleagues began to use the tool.”
