Podcast: Advancing Deep Learning with Custom-Built Accelerators

In this Chip Chat podcast, Carey Kloss from Intel outlines the architecture and potential of the Intel Nervana NNP-T. He gets into major issues like memory and how the architecture was designed to avoid problems like becoming memory-locked, how the accelerator supports existing software frameworks like PaddlePaddle and TensorFlow, and what the NNP-T means for customers who want to keep on eye on power usage and lower TCO.

Donald Knuth on Algorithms, Complexity, and The Art of Computer Programming

In this Artificial Intelligence podcast with Lex Fridman, computer scientist Donald Knuth discusses Alan Turing, Neural networks, machine learning and other AI topics from ant colonies and human cognition.

Radio Free HPC Rings in the New Year

“It’s become a tradition at Radio Free HPC to celebrate the holidays with a video of the holiday episode. The new logo launches the video: celebrating a truly family style dinner and dreaming big (maybe too creatively, however) as the team exchanges “if-only” gifts!”

Mapping Disasters with Artificial Intelligence

In this Chip Chat podcast, Intel’s Alexei Bastidas describes the technology behind making maps from satellite images. “Good maps rely on good data. The Red Cross’ Missing Maps Project leverages AI to provide governments and aid workers with the tools they need to navigate disasters like hurricanes and floods. Using a wealth of satellite imagery and machine learning, the Missing Maps Project is working to make villages, roads, and bridges more accessible in the wake of devastation.”

Podcast: The Evolution of Neuromorphic Computing

Intel’s Mike Davies describes Intel’s Loihi, a neuromorphic research chip that contains over 130,000 “neurons.” “To be sure, neuromorphic computing isn’t biomimicry or about reconstructing the brain in silicon. Rather, it’s about understanding the processes and structures of neuroscience and using those insights to inform research, engineering, and technology.”

An Alternative to OpenMP and an On-Ramp to Future C++ Standards

In this edition of Let’s Talk Exascale, Christian Trott of Sandia National Laboratories shares insights about Kokkos, a programming model for numerous Exascale Computing Project applications. “Kokkos is a programming model being developed to deliver a widely usable alternative to programming in OpenMP. It is expected to be easier to use and provide a higher degree of performance portability, while integrating better into C++ codes.”

XSEDE Supercomputers Advance Skin Cancer Research

In this TACC podcast, UC Berkeley scientists describe how they are using powerful supercomputers to uncover the mechanism that activates cell mutations found in about 50 percent of melanomas. “The study’s computational challenges involved molecular dynamics simulations that modeled the protein at the atomic level, determining the forces of every atom on every other atom for a system of about 200,000 atoms at time steps of two femtoseconds.”

CHPC Student Cluster Winners Get Ready to take ISC by Storm

In this podcast, the Radio Free HPC recaps the recent CHPC National Conference in South Africa. “Now a 5-day conference with two days of workshops as book-ends, multiple tracks and many speakers, and yes, a very exciting Student Cluster Competition, the CHPC National Conference has developed into a very important event in the HPC/AI world. Dan Olds takes us through what he saw, who won, and what we can expect at the competition at ISC in 2020, and just how impressive the whole thing was.”

Podcast: Developing Multiprecision Algorithms with the Ginkgo Library Project

In this episode of Let’s Talk Exascale, Hartwig Anzt from the University of Tennessee describes how the ECP Ginkgo Library Project is developing a vision for multiprecision algorithms. “Anything reducing the data transfer volume while still communicating the information can help make use of the software more efficient. Benefits are available even if the decreased data transfer volume comes at the cost of additional operations.”

Podcast: UnifyFS Software Project steps up to Exascale

In this Let’s Talk Exascale podcast, Kathryn Mohror LLNL and Sarp Oral of ORNL provide an update ECP’s ExaIO project and UnifyFS. “UnifyFS can provide ECP applications performance-portable I/O across changing storage system architectures, including the upcoming Aurora, Frontier, and El Capitan exascale machines. “It is critically important that we provide this portability so that application developers don’t need to spend their time changing their I/O code for every system.”
