Radio Free HPC Discusses the IO500 Benchmark Suite with John Bent

In this podcast, the Radio Free HPC team talks to John Bent from the IO500 committee about why he and a team of I/O professionals created the IO500 benchmark suite. The second IO500 list was revealed at ISC 2018 in Frankfurt, Germany. “The current list includes results from BeeGFS, DataWarp, IME, Lustre, and Spectrum Scale. We hope that the next list has even more.”

Radio Free HPC Reviews Lincoln Labs Paper on Spectre/Meltdown Performance Hits

In this podcast, the Radio Free HPC team looks at a new whitepaper from Lincoln Labs focused on the performance hits Spectre/Meltdown mitigations. The news is not good. After that, Shahin point us to the story about how DARPA just allocated $75 Million in awards for thinking-outside-the-box computing innovation. They call it the Electronics Resurgence Initiative and the list of projects funded includes something called Software Defined Hardware.

Podcast: Bill Dally from NVIDIA on What’s Next for AI

“NVIDIA researchers are gearing up to present 19 accepted papers and posters, seven of them during speaking sessions, at the annual Computer Vision and Pattern Recognition conference next week in Salt Lake City, Utah. Joining us to discuss some of what’s being presented at CVPR, and to share his perspective on the world of deep learning and AI in general is one of the pillars of the computer science world, Bill Dally, chief scientist at NVIDIA.”

Podcast: Supporting Multiphysics Application Development

In this episode of Let’s Talk Exascale, Computational scientist Ben Bergen of Los Alamos National Laboratory describes the Advanced Technology Development and Mitigation (ATDM) subprogram‘s Flexible Computational Science Infrastructure (FleCSI) project.

Radio Free HPC Looks at China’s Three-Pronged Plan for Exascale

In this podcast, the Radio Free HPC team goes through a fascinating presentation that provides details on China’s Three-Pronged Plan for Exascale. “China may not be the first to Exascale, but they are building three divergent architectural prototypes that pave the way forward. We’ve got the details in this not-to-miss podcast.”

Penguin Computing to Deploy Supercomputer at ICHEC in Ireland

Today Penguin Computing (a subsidiary of SMART Global Holdings) announced that it will deliver the new national supercomputer to the Irish Centre for High-End Computing (ICHEC) at the National University of Ireland (NUI) Galway. “With 11 supercomputers in the Top500 list and a bare-metal HPC Cloud service since 2009, we knew we could rely on Penguin Computing’s HPC expertise to address our needs in an innovative way.”

Podcast: Deep Learning for Scientific Data Analysis

In this NERSC News Podcast, Debbie Bard from NERSC describes how Deep Learning can help scientists accelerate their research. “Deep learning is enjoying unprecedented success in a variety of commercial applications, but it is also beginning to find its footing in science. Just a decade ago, few practitioners could have predicted that deep learning-powered systems would surpass human-level performance in computer vision and speech recognition tasks.”

Podcast: Evolving MPI for Exascale Applications

In this episode of Let’s Talk Exascale, Pavan Balaji and Ken Raffenetti describe their efforts to help MPI, the de facto programming model for parallel computing, run as efficiently as possible on exascale systems. “We need to look at a lot of key technical challenges, like performance and scalability, when we go up to this scale of machines. Performance is one of the biggest things that people look at. Aspects with respect to heterogeneity become important.”

Radio Free HPC Trip Report from ISC 2018

In this podcast, the Radio Free HPC team offers up a Trip Report from ISC 2018 in Frankfurt. It was a whirlwind week for news with a new USA machine on the TOP500, but the other big news centered around the convergence of HPC & AI. This common theme was all over the show floor, with use cases on display in dozens of exhibits. 

Podcast: Supercomputing New Enzymes for Breaking Down Plastics

In this TACC podcast, Gregg Beckham from NREL and Lee Woodcock from the University of South Florida describe how they are using supercomputers to engineer an enzyme that breaks down plastic. “We used computer simulations to understand how a polymeric ligand like PET would be able to bind to the enzyme,” said study co-author Gregg Beckham, a Senior Research Fellow and Group Leader at the US National Renewable Energy Laboratory (NREL). “We also conducted experimental work to show that indeed, the PETase can break down water or soda bottles, industrially relevant PET films, and another plastic, polyethylene furanoate.”
