Podcast: Honeywell Traps, Zaps Ions for Science

In this podcast, the Radio Free HPC team looks at Honeywell’s Trapped Ion Quantum computing initiative. Quantum computing initiative. “Shahin gives us a good overview of digital vs. analog and classical vs. quantum science. The Honeywell system is in the ‘quantum-gate’ quadrant of Shahin’s model, suspending ions in space through magnetics and then hitting them with lasers to produce entanglement. The Honeywell system is interesting because it is scoring well on the emerging Quantum Volume metric – showing very high fidelity for its qubit count. This system is the culmination of over 10 years of R&D and should be on the market later on this year.”

Podcast: AI for Science

In this podcast, the Radio Free HPC team looks at the AI for Science program coming out of Argonne National Laboratory. “This is one of the biggest potential changes in our industry and well worth the investigation. But figuring out where AI fits into the traditional world of research and simulation is a difficult problem. Henry points out that nearly every grant proposal needs to include ‘AI’ in order to get serious consideration.”

Podcast: Supercomputers Battle Coronavirus

In this podcast, the Radio Free HPC team looks at how supercomputers are being used to battle the coronavirus. “We discuss how the supercomputing community has joined the fight and the impact on the battle against the virus. We do our best to keep the conversation light, knowing that everyone out there is suffering from the virus – it’s the one thing we all have in common these days.”

Podcast: A Look inside the El Capitan Supercomputer coming to LLNL

In this podcast, the Radio Free HPC team looks at some of the more interesting configuration aspects of the pending El Capitan exascale supercomputer coming to LLNL in 2023. “Dan talks about the briefing he received on the new Lawrence Livermore El Capitan system to be built by HPE/Cray. This new $600 million system will be fueled by the AMD Genoa processor coupled with AMD’s Instinct GPUs. Performance should come in at TWO 64-bit exaflops peak, which is very, very sporty.”

Podcast: One Big Debate over OneAPI

In this podcast, the Radio Free HPC team looks at Intel’s oneAPI project. “The OneAPI project is a highly ambitious initiative; trying to design a single API to handle CPUs, GPUs, FPGAs, and other types of processors. In the discussion, we look under the hood and see how this might work. One thing working in Intel’s favor is that they’re using data parallel C++, which is highly compatible with CUDA – and which is probably Intel’s target with this new initiative.”

Podcast: Applying Deep Learning to Extreme Weather

“A research team from Rice University utilized three supercomputers (TACC’s Stampede 2, Wrangler, and Pittsburg Supercomputing Center’s Bridges system) to see if data on heat waves and cold spells could be predicted by analysis of atmospheric circulation and prior surface temperature. The results of these tests indicated that this deep learning approach is more accurate at predicting extreme weather.”

Podcast: Slingshotting to Exascale

In this podcast, the Radio Free HPC team looks at the Cray Slingshot interconnect that will power all three of the first Exascale supercomputers in the US. “At the heart of this new interconnect is their innovative 64 port switch that provides a maximum of 200 Gb/s per port and can support Cray’s enhanced Ethernet along with standard Ethernet message passing. It also has advanced congestion control and quality of service modes that ensure that each job gets their right amount of bandwidth.”

Podcast: Tracking the Coronavirus with HPC

In this podcast, the Radio Free HPC team looks at how supercomputing can help predict and track the progress of the Covid-19 virus. “Shahin also wonders about the economic effect on the tech business as inventories dry up while producers are sidelined by the virus.”

Podcast: AMD to Power New ECMWF Supercomputer for Weather Forecasting

In this podcast, the Radio Free HPC looks at the new ECMWF supercomputer. “This new system will give them roughly 5x more compute power than their current system. The new box is an Atos BullSequana XH2000 fueled by high-end AMD 7742 Epyc processors, which will be the most powerful weather computer in the world. During the conversation we look at the history of ECMWF vendors, discuss the implications on weather forecasts given the power of this new system and the computational difficulties inherent in weather prediction.”

Podcast: The Trouble with ZFS

In this podcast, the Radio Free HPC team discuss whether ZFS is ever going to meet its potential. “Henry weighs in on the evolution of ZFS and how his opinion of ZFS has changed over the last decade or so. Both Shahin and Henry feel ZFS is unique and highly useful and that maybe Linus isn’t up on current ZFS capabilities.”
