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: 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.”

Podcast: When a Different OS Gets Different Results

In this podcast, the Radio Free HPC team looks at problems in the scientific software world. “There’s a bug in Python scripts that caused different results in identical routines run on different operating systems. As the guys discuss, it’s not a Python thing but a problem with the order in which files got read according to the operating system’s protocols. This impacts the sort order and thus the end results. The gang speculates on other causes of these types of problems and the fixes that should be employed.”

Podcast: The Turing Machine is Sequential, so how about a Parallel Machine?

The @RadioFreeHPC team is joined by the folks at MemComputing, a San Diego startup that’s built a new parallel foundation for computing. It calls it the universal memcomputing machine, and a realization of self-organizing circuits. “We analytically prove that the memory properties of UMMs endow them with universal computing power—they are Turing-complete.”

Podcast: Quantum Supremacy? Yes and No!

In this podcast, the RadioFreeHPC team discusses the Google/NASA paper, titled “Quantum Supremacy Using a Programmable Superconducting Processor”, that was published and then unpublished. “The tantalizing promise of quantum computers is that certain computational tasks might be executed exponentially faster on a quantum processor than on a classical processor. A fundamental challenge is to build a high-fidelity processor capable of running quantum algorithms in an exponentially large computational space.”

Podcast: FinTech and HPC-AI

In this podcast, the Radio Free HPC team looks back at the HPC-AI on Wall Street conference. “We discuss the well-received Cryptocurrency panel that he moderated, the challenges of using of AI in financial services, the emerging computational storage, and advanced HPC-class modeling that helps venture capital investors decide whether to invest in a startup.”

Podcast: Extreme Power and Cooling Efficiency at DownUnder GeoSolutions

In this podcast, the Radio Free HPC team looks at an interesting presentation on Power and Cooling by Stuart Midgley from DownUnder Geosolutions. Their 250 Petaflop “Bubba” supercomputer uses immersive cooling for extreme density and power efficiency.

Podcast: IO500 Benchmark Gains Traction

In this podcast, Radio Free HPC hosts the IO500 Steering Committee. “Storage is complicated and benchmarking it has too many complexities for the traditional kernel-like or application-specific approaches. Thanks to a few experienced and tenacious researchers, and the community that supports them, the IO500 has managed to put a credible stake in the ground, and is getting traction, with 101 entries on the current list and expecting many more by SC19.”

Radio Free HPC Recaps the Hot Chips Conference

In this podcast, the Radio Free HPC team is joined by Glenn Heinle to review the highlights of the Hot Chips conference. “Since it started in 1989, HOT CHIPS has been known as one of the semiconductor industry’s leading conferences on high-performance microprocessors and related integrated circuits. The conference is held once a year in August in the center of the world’s capital of electronics activity, Silicon Valley.”

Podcast: Cray Pulls an Exascale Hat Trick

In this podcast, the Radio Free HPC looks at Cray’s series of big wins for DOE Exascale systems. “Guess who’s having a great year? Think Aurora, Frontier, and El Capitan. Cray has put some nice numbers on the accounts receivable ledger, and these are not ordinary numbers. The Exascale era is being defined substantially by the DOE Coral program and the commercial markets are watching as their computing needs start looking like those of the national labs.”
