Podcast: SCR Scalable Checkpoint/Restart Paves the Way for Exascale

A software product called the Scalable Checkpoint/Restart (SCR) Framework 2.0 recently won an R&D 100 Award. In this episode, Elsa Gonsiorowski and Kathryn Mohror of LLNL discuss what SCR does, the challenges involved in creating it, and the impact it is expected to have in HPC. “SCR enables HPC simulations to take advantage of hierarchical storage systems, without complex code modifications. With SCR, the input/output (I/O) performance of scientific simulations can be improved by orders of magnitude.”

Radio Free HPC Recaps the SC19 Student Cluster Competition

In this podcast, the Radio Free HPC team recaps the SC19 Student Cluster Competition. “We talk about the student configurations, kicked around the pros and cons of the “small is beautiful” movement in the student cluster competition world. “Does the trend towards fewer-bigger nodes mean a re-emergence and eventual re-victory of SMP over MPP?” wonders Shahin! No records in HPL or HPCG, but some good scores regardless.”

Podcast: Digital Trust in the Age of Deepfakes

In this podcast, the Radio Free HPC team catches up with Dave Maher, CTO of internet security company Intertrust, to share with us his deep knowledge of digital communication, identity management, data rights management, cryptography and digital certificates, blockchain, and much more.

Radio Free HPC Breaks Down the TOP500

In this podcast, the Radio Free HPC teams looks at the newly released TOP500 list. “We talk about the changes in this version of the list (100 new systems, but none in the top 24), how the major countries stack up against each other, and vendor system share. We also discuss why this list is so, well, kind of not as exciting as we’ve got used to, and what we expect to see on future lists. There are some big things coming, but, like your birthday, they’re not here yet.”

Slidecast: Dell EMC Using Neural Networks to “Read Minds”

In this slidecast, Luke Wilson from Dell EMC describes a case study with McGill University using neural networks to read minds. “If you want to build a better neural network, there is no better model than the human brain. In this project, McGill University was running into bottlenecks using neural networks to reverse-map fMRI images. The team from the Dell EMC HPC & AI Innovation Lab was able to tune the code to run solely on Intel Xeon Scalable processors, rather than porting to the university’s scarce GPU accelerators.”

Podcast: SC19 Student Cluster Competition Preview

In this podcast, the Radio Free HPC team catches up with Jessi Lanum, a veteran of the SC19 Student Cluster Competition, for an insider peek on what it’s like to compete for cluster competition glory. “For the few of you who are not already fans of these events, here’s the lowdown: 16 student teams representing universities from around the world have been working their brains out designing, building, and tuning clusters provided by their sponsors. They can use as much hardware as they want, the only limitation is that their systems can’t use more than 3,000 watts during the competition.”

Podcast: Full Rundown of SC19 Events in Denver

In this podcast, the Radio Free HPC team reviews the full list of events leading up to SC19 in Denver. “There’s a lot that happens before the exhibit floor opens on Monday night. Our old pal Rich Brueckner from insideHPC joins us to give us the full rundown. We even have a few parties to tell you about.”

Radio Free HPC Celebrates 251st Episode

In this podcast, the Radio Free HPC team celebrates their 251st episode. “Not enamored with round numbers, the team notes that 251 is a prime number and round enough for celebration. This is not quite a “highlights” show, but a look back at how RadioFreeHPC came about, who came up with the name RadioFreeHPC, how the show has evolved, a bit of “remember when”, a few notable episodes, and the meteoric rise of its listenership!”

Podcast: Inventing the Future with AI for Science

In this Sound of Science podcast, researchers from ORNL dispel some of those myths and discuss how AI is transforming cancer research, manufacturing and plant biology. “Artificial intelligence is no longer just a subject of science fiction. From personal assistants to self-driving cars, AI is revolutionizing everyday life. While AI may be more prevalent these days, there are still a lot of misconceptions about what it is and what it isn’t.”

Podcast: RISC-V CEO Sees Bright Global Future for Open Source CPUs

In this podcast, the Radio Free HPC team catches up with Calista Redmond, CEO of RISC-V. “RISC-V can be used for light weight tasks such as embedded processing but, on the other hand, is also going to be utilized as the system accelerator for the European Exascale initiative boxes. That’s some serious flexibility.”
