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.

We start off with an update from our crew. Jessie is at Purdue putting her belongings into storage in order to clear out her current abode. Shahin is doing fine, all quarantined up down in Silicon Valley. Henry has big news: he’s completed his north-south journey and is now staying in a hotel very close to his newly constructed survivalist bunker near scenic Los Cruces, NM. What’s great for the workers finishing up the house is that Henry will now be there EVERY DAY to help them expedite construction and offer pro tips. That must be a dream come true for them.
Henry also announced that he’s going to host us RadioFreeHPC hosts for a live broadcast from his compound sometime in August. He’ll have his home pizza oven fired up and we’ll have a veritable feast while taking copious video of his new bunker and putting together a couple of shows. It should be a lot of fun.
Getting to our main topic, we discuss how the server business has been very healthy in the first quarter – growing more than 30% – which is astounding given these virus laden times. Henry links these results to his research that shows that Akami’s bandwidth use has grown a similar 30% during the first quarter. We speculate (and argue a little) over whether the bump in server sales can be attributed to folks buying pre-emptively to handle anticipated demand or whether they’re meeting current demand. Shahin and Dan feel that there was already excess capacity, since there haven’t been any reports of internet speed/capacity problems during the quarantine.
Our discussion continues on with speculation about just when the supply chain kink caused by the virus impacting component makers will hit the market. The lost production can’t be made up instantly and we also believe that there is probably going to be a demand shock at least with enterprise and, to a lesser extent HPC customers, because they simply don’t have the will to launch new IT projects in this environment. We’re not entirely sure we buy these numbers, since it’s from an analyst firm we’re not familiar with.
Reasons Why No One Should Ever Be Online. Ever.
Henry dug up a very timely hack this week, with an article detailing how hackers have built a Trojan Horse version of the widely-used Zoom video conferencing software. If you download Zoom from the wrong place, it will install Zoom – but with added ‘features’ that will allow hackers to pown your box – definitely not fun. So be sure you get your Zoom from either the company itself or from a reputable source.
Catch of the Week
Jessi: Her topic is how spending on cyber security lobbying has more than tripled in the last few years. The cybersec folks are, thankfully, lobbying in favor of more security and privacy, often in direct opposition to industry giants Facebook and Google.
Henry: The above referenced Akami article is Henry’s catch. He discusses how Akami is pumping out 167 terabits of data per second, but warns that this won’t be nearly enough when you consider the potential additional traffic due to the conversion to 5G. He puts forward a compelling argument that web infrastructure isn’t ready for the data deluge that is 5G. Nicely done, Henry.
Shahin: Brings up our recent “Charles Babbage: His Life & Times” dramatic presentation (it was awesome) to discuss how Baidu is now able to clone voices with just 3.7 seconds of samples. With more samples, it can change accents and even genders. He suggests that this could be good for our next drama foray.
Dan: Starts a group discussion about how some college students are now suing their host institutions over Covid19 disruptions in order to get a portion of their tuition and fees returned or reduced. Jessi, as our resident undergrad, weighs in with several powerful points while the others chip in with their old man knowledge.
