HPC on the Edge

Edge Computing Book Makes Sense of It All

After our typical inane opening, which includes an update on Henry’s Las Cruces bunker with  21” rammed earth walls, we get quickly down to business and begin our interview with very special guest, Dr. Cody Bumgardner, Assistant Professor of Pathology & Laboratory Medicine at the University of Kentucky.

Our topic? Edge computing, what it is, what is isn’t, and why it’s important. Cody has just authored a book “Making Sense of Edge Computing.”

Dan starts us off with a question about the definition of edge computing, which as it turns out, covers a lot of ground. Henry comes in with a question about how 5G might impact edge computing and Shahin follows up by asking if 5G really has much to do with edge computing at all. There is some overlap, but 5G is a transmission mechanism rather than a computing mechanism, meaning that it’s the 5G device and what it is tasked to do that can make it either an edge device or not an edge device.

As the show goes on, we talk about the edge capacity in place and what still needs to be built, along with current and potential use cases. A good time is had by all.

Reasons Why No One Should Ever Be Online. Ever.

Henry shocks us yet again with news that people are being scammed by work-at-home deals that are actually ‘money mule’ schemes to help criminals launder their ill-gotten gains. Dan seems a little too curious about the mechanics and potential pay-offs of these deals. 

Catch of the Week

Jessi: Jessi is pointing out that she has now moved for the third time in one academic semester and that she has more books than anything else. Ouch.

Henry:  Henry is off yelling at his contractors when his turn comes up, so no catch from him this week.

Shahin:  Article about how to program Aurora, highly recommended by Shahin.

Dan:   Discusses how the ISC2020 Student Cluster Competition will be virtual this year. He’ll be covering it as usual, but with a LOT of Zoom. Every team is going to be using the same cluster, but sharing it. Stay tuned for more news.

Debate This: Server Sales Up 30% in Q1, Says Analyst Firm

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.

2020 Predictions, Get it?!

Shiny Crystal Ball

It’s our first episode of 2020, yay! The first that was recorded in 2020 anyway.  It's a predictable 20/20 joke (more of a meh comment really) but the topic today is... PREDICTIONS. More specifically, it's our predictions of what’s going to happen in the next year. We may not always be correct, but we think maybe we’re always certain. We look at compute, interconnects, security, and general innovations:

Compute

Dan says that we’re going to have more of it. Henry predicts that we’ll see a RISC-V based supercomputer on the TOP500 list by the end of 2020 – gutsy call on that.  This is a double down on a bet that Dan and Henry have, so he’s reinforcing his position. Dan also sees 2020 as the “Year of the FPGA” when we start to see more and more HPC boxes fueled by FPGA, which is something Shahin mostly agrees with while Henry disputes it. We also touch on liquid cooling and process size as part of this topic.

Interconnects

Dan thinks that InfiniBand will announce 400 GBs interconnect by the end of this year – a bold prediction. On a communications note, Henry says that 20% of the US user base will have access to 5G phone coverage by the end of the year. Shahin asserts that only 3% of the market will actually buy it, but Dan and Henry say not so fast – it’ll be closer to 10%. Shahin is looking for a 5G connection for servers. Not as an interconnect, but more as a WAN or a cluster that spans an entire county. On another note, Shahin believes that HPE will formally get into the interconnect business, selling the Slingshot interconnect.

Security Trends

Dan says we need more of it but doesn’t see anything that’s going to move the needle back towards the users. Jessi thinks that security education has improved things security-wise and that will continue in 2020. Henry and Dan disagree. Jessi is adamant.

Innovation/Trends

Dan pegs in-memory computing as a field that will blossom over the coming year(s). Shahin agrees that in-memory is very interesting and ripe for innovation as well. But he also sees a lot of developments in the AI processor space. Henry talks about a new application workflow that will go something like this:  Object > MemMap > Compute on the MemMap file/data > back to Object, with no POSIX in the way. Shahin also sees more quantum supremacy in the news in the coming year.

Letter(s) to the Editor!

We discuss our first letter to the editor, from a listener who wasn’t a fan of the episode where we answered Jessi’s question about why tape is still used. His term for that feature? “Poor.” This prompted Shahin to quip, “I’m surprised we don’t get more of these…..”  Please keep those comments (good, indifferent, or critical) coming, our email is podcast@radiofreehpc.com.

Why Nobody Should Ever be Online. Ever.

This week, Henry doesn’t have a “Reason Why No One Should Ever Be Online. Ever.” He was offline all week, so thus doesn’t have anything to scare us with.

Catch of the Week

Henry:  has no catch, his net came up empty.

Shahin:  was practicing Catch & Release this week, so his creel is fishless.

Jessi:  discusses her new phone. She lost her old one in a Czech toilet (nasty, yikes). This is her first phone upgrade since junior high school – probably 6-7 years – and she’s agog at how the phones have advanced. She can now take pictures and use apps. Yay Jessi!

Dan:   Encourages listeners to have a good year and to let us know what you think via email (podcast@radiofreehpc.com) and twitter (@radiofreehpc). He also highlights the new RadioFreeHPC logo along the way.

Quantum Apps Are Hybrid

"Quantum applications are always and only hybrid" is the quote that Shahin wants you to remember as he gives an update on recent news in Quantum Computing, and especially how to program them. If you're always going to have to mix classical code with quantum code then you need an environment that is built for that workflow, and thus we see a lot of attention given to that in the QIS (Quantum Information Science) area. This is reminiscent of OpenGL for graphics accelerators and OpenCL/CUDA for compute accelerators.

Henry talks about 5G and how people are starting to get serious bandwidth: 1.8 gbps has been seen on existing smart phones. Henry's super fast cable modem set-up is delivering 220 gbps and 16ms latency. And 5G is only going to get better with advertised peaks of 20 gbps and 4ms latency depending on frequency and handset and power, etc. Everyone then picks on an easy target: DSL.

Dan gives a heartfelt farewell to the retiring Titan supercomputer, complete with the matching sombre music in the background, which, discerning listeners will note, plays only when he's talking. Affection for Titan continues in its memory, and we imagine possibly also its DRAM.

Catch of the Week

Henry:

Another week another cyber-security breach! Henry has a few of them but it's all too depressing, so he decides to pass this week.

Shahin:

Shahin is looking forward to attending the Hot Chips conference to be held at Stanford August . Henry is envious, given the technology candy store that the conference represents. Shahin promises to take good notes and report back in a future episode. Let him know if you'll be there.

Dan:

Dan talks about cyber-attacks and ransomeware targeting small and mid-sized cities, the impact on insurance rates, and what a hard problem that is to solve.
