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.

  • Episode 257: SC19: Our Visit to the State Fair

    By admin | December 13, 2019 |

    SC19 Postview

    Our show today is all about what we saw at the “State Fair for Nerds” that is SC19. Where there weren’t any livestock shows or supercomputers carved out of butter, there was a lot to see and hear.

    Shahin talks about the European Processor Initiative and conversations that he had with folks from the Barcelona Supercomputing Center, the quantum computing briefing by D-Wave, and a chat with Cold Quanta.

    We reiterate the bet between Henry and Dan, where Henry bets Dan that there will be a RISC-V based system on the TOP500 system by SC20. The stakes? The winner gets the dinner of his choice paid for by the loser.

    Jessi went to the keynote by Dr. Squires and notes that someone asked him “where did you use HPC systems in your project?” This prompts Jessi to ask us if it’s kosher to have keynotes which don’t necessarily hit directly on HPC. We discuss how there have been non-HPC centric keynote speakers at several SC events in the past….see Al Gore, Alan Alda, Bill Gates, Michael Dell, etc.

    Dan brings up the news from NVIDA about how they’ve gathered a consortium of big-time industry players who will be working on adapting ARM processors for accelerated computing. We speculate on whether Fujitsu will be contributing their very sporty new ARM chip to the group, with thoughts of licensing it for use by other vendors. In other NVIDIA news, Azure now has eight GPU instances connected by InfiniBand interconnects.

    Why Nobody Should Ever Be Online. Ever

    This week Henry has a reason why no one should ever go to a local doctor again. Ever. He cites an article about how a small doctor and dental office service provider suffered a ransomware attack, which meant that the doctors they were managing archiving for could no longer get access to their records. If this can happen to service providers, it can run these smaller providers out of business as HIPPA regulations and fine are onerous. Dan comments that he only goes to vets for medical services (just like Kramer on Seinfeld).

    Things You Think You Know, But Might Not

    In this installment, Jessi asks the panel about interconnects, why we need them, what they do, and what are your choices. Dan jumps in with discussing Ethernet and InfiniBand, while Henry jokingly brings up Token Ring. More helpfully, Henry discusses proprietary interconnects and things like RDMA and ROCE. Shahin believes he has the definitive answer, which is the start of his Computing 301 Lecture Series. This leads into a slight tangent where we discuss SMP vs. MPP and how coherency at scale is incredibly expensive.

    Catch of the Week

    Shahin: Talks about a young man who bought his own IBM z/890 mainframe for $350 and installed it in his parent’s basement. Amazing feat. He has it running and now has the only mainframe in his neighborhood. Congrats to Connor. IBM needs to hire this young man and harness his passion.

    Jessi:  Getting or giving an Alexa or Google Home device? Better think twice and then think again. Big time security flaws in both devices.

    Henry: Has no catch of the week. He’s looking at -14°F and has to go out and shovel snow.

    Dan: Biggest tech flops of 2019. Includes We Work, Samsung Fold, hacks of VPNs, Facebook Libre and other ignominious failures.

    Did you say logo?

    Most of you probably didn't know that RadioFreeHPC even has a logo, Dan thinks as he gives an update on a project to update the logo, in several colors. Getting closer to the sure-to-be-coveted RadioFreeHPC merch we all wanted!
