Topics including (but not limited to)....
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.
- They are computationally intense
- Time to solution and quality of solution are critical
- 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.

For RadioFreeHPC aficionados, it’s a typical opening for this episode. Henry is counting down the days until he moves to sunny Los Cruces and we have a lull in the conversation right after the introductions. We recover quickly and move onto the main course of today’s show:
Intel’s OneAPI project
The OneAPI project is a highly ambitious initiative; trying to design a single API to handle CPUs, GPUs, FPGAs, and other types of processors. In the discussion, we look under the hood and see how this might work. One thing working in Intel’s favor is that they’re using data parallel C++, which is highly compatible with CUDA – and which is probably Intel’s target with this new initiative. Henry points out that porting codes is a pain and that no one wants to port to another API if it can possibly be avoided, so he predicts that most customers will not want to use it and if they consider it, before they move any code, they need to be sure that this new API is going to stick around for many years.
Shahin is generally positive on the project. Henry and Dan to have a rare moment of agreement in disputing Shahin’s thoughts about several things! Let's start with his view that Java has provided portability in exchange for performance – and then improved its performance. Henry and Dan take issue with this, with Henry saying that Java provides little real performance and Dan saying that programs have changed to provide Java performance rather than Java changing to provide performance. Shahin believes that OneAPI is a good thing for the industry and will be successful. Dan believes it’s a good thing for Intel, but has doubts about whether it’s good for the industry. Henry doesn’t see big adoption for the foreseeable future saying, “It has a long way to go and it’s a significant risk.” Dan and Henry end up agreeing and agreeing to disagree with Shahin. Jessi is safely on the fence on this one.
It’s a very good conversation, well worth a listen.
Why Nobody Should Ever be Online. Ever.
This week, Henry shares a personal story about key fobs and a very troubling problem he found with his latest rental car. It has everything, thrills, chills and a shocking conclusion.
Catch of the Week
Jessi: The Department of Defense has built a supercomputer in a shipping container, for sending to wherever its computation is needed. The supercomputer itself is designed to work on AI-related problems, and falls under the classification of "AI on the edge," where data is processed in the same location it is collected. While it’s not news, it’s news to Jessi and it’s cool, so it’s her catch of the week.
Shahin: Tells the story of a reporter renting a shared car service, which is unlocked by a cell phone. The reporter ventures out into the hinterlands a little bit and finds that she can’t get the car to work anymore. Why? Because there wasn’t enough cell phone coverage to properly start the car – meaning that the reporter had to wait (and wait) for a person to be sent out to physically interact with the car and get it going again. Yikes – think out your products, people, ok?
Henry: Hackers made a home for themselves inside Citrix for five months, siphoning off personal and financial information. Yikes again. The company had to be alerted by the FBI to the hack and, assumedly, their internal tools didn’t pick up the penetration. That’s a long time to be exploited!
Dan: McAfee researchers show that just a few strips of tape on a road sign can prompt a Tesla car to accelerate by an astounding 50 miles per hour over the posted speed limit on that sign. According to Dan, this is a bad thing.
