Radio Free HPC (RFHPC) started in 2012 and, after a short break of 193 months, has returned to the airwaves (cyber waves?) with co-hosts Dan Olds, Henry Newman, and Shahin Khan.

The podcast covers a wide range of topics but is particularly focused on data center technology and challenges. These include high performance computing, power and cooling, new technology, and, really, whatever the hell they want to talk about.

 

Quick FAQ


"Why are you just covering HPC? There's this new thing called AI, have you heard of it?"

Yeah, we've heard of it and we do cover it. To us, HPC is a broad term used to refer to a very broad group of apps/workloads that have common characteristics.

  1. They are computationally intense
  2. Time to solution and quality of solution are critical
  3. The output is important enough to justify investment in high-end clusters and associated hardware/software

AI meets all of the criteria above just like bioscience, aerospace, weather prediction, and several other domains. In fact, AI is or will soon be folded into the workflows of nearly every 'traditional' HPC and enterprise application over time. This is going to put a lot of pressure on data centers and we'll be talking about how to deal with it.

 

"Was the old version of Radio Free HPC popular? I've never heard of it..."

Yes, it rose from obscurity to being mildly popular and, at times, entertaining. At our peak, we had as many as 16 sustained listeners and as many as 19 theoretical max listeners.

 

"I listened to the old show a couple of times and liked the arguing. Will there be more of that in this reboot?"

Yes, in fact we expect as much as 29% more arguing and a significant increase in the number of personal insults per episode.

 

"How often will this thing come out and how do I find out about it?"

We used to try to do weekly shows but failed due to other commitments, travel, etc. And there were just weeks when nothing important happened. But to answer your question, could be every couple of weeks, could be once a month, or we could record a marathon 8-10 hour single episode. Depends on what's happening and our mood.

We're getting together our RSS feeds and such but in the short term we'll be publicizing the episodes through the RFHPC X account and our individual social media accounts.

 

Ok, enough questions. If you want to learn more about the show and hosts, check out the "About" page.

Here are our most recent episodes along with the 345 or so previous editions, enjoy!

 

 

 

Latest Episode

  • Episode 272: What Good Did It Do? Quite a Lot, and Quite the Story

    By admin | May 2, 2020 |

    A typical show opening, but we’re missing Henry – he was away packing for his big move from his long-time home base in Minnesota to his new bunker in Las Cruces. He’s packing up all of his memorabilia, like his first punch card sets, his core memory collection and his home terminal, lovingly wrapping them up for the long trip south.

    News Alert

    NEWS ALERT:  we interrupt this show blog for a special announcement. We’re having a contest! This is the digital version of the "18th caller" contest. The 18th emailer to RFHPC, starting now, will receive what Dan might describe as a fantastic prize from us at Radio Free HPC. Send in your email entries now, and listen to the show for details. This might take a couple of weeks, it might take a couple of years, but we're nothing if not good with small numbers and large units. And that 18th lucky emailer deserves a prize.

    A Cool New Book Project

    We have a special guest today, David Barkai, a 50-year veteran of HPC. David has worked in a wide variety of positions at NASA, Intel, Cray, SGI and others. His project now is writing a book to chronicle the last 50 years in HPC told from the perspective of those who were there.

    The main emphasis in the book is examining the good that HPC has done in the world, which is quite the story. He’s looking at the applications that have changed the world, from weather forecasting to safer and quieter cars and so on, and the system architectures that have made them possible in a decade-by-decade tour of HPC development.

    • 1970s:  Vector Processors
    • 1980s:  Multiprocessors
    • 1990s:  Massive Parallelism
    • 2000s:  Clusters and Accelerators
    • 2010s and beyond:  HPC and AI/Cloud

    As David says in our interview, the top HPC systems have advanced 10-15 times faster than Moore’s Law, which is astounding. In the book he goes into detail about how the industry drove performance at such a dizzying pace. He’s still writing away and is interested in hearing about your HPC journey to help fill out the book. You can reach him here.

    Reasons Why No One Should Ever Be Online. Ever.

    Henry is practicing what he preaches and is not online right now as he waits to the internet company to get him connected again.

    Catch of the Week:

    Jessi:  Google’s head of Quantum computing hardware resigns. John Martinis resigned after being assigned to an advisory role in the company.

    Shahin:  Discusses a paper on Coarse Grain Reconfigurable Architecture (CGRA) as a way of having performance and programmability closer to the metal. Its survey of what's been going on in this area with FPGAs is great and may also point to what we can expect in future supercomputers.

    Dan:  Subs for Henry with a horrible impression for a first catch. But his real catch is a plug for the Radio Free HPC Studio Products production of “Charles Babbage, his life and times.”  It’s an impressive production with chills, thrills and plenty of action. Don’t put it off, listen now. All those reviews are great for a reason!
