Is it Time for Virtual GPUs?

VMware's Bitfusion and Dell

We start with team introductions, as usual, but drop a bombshell on listeners:  we’re going to be missing Jessi for the next couple of months as she goes off to Marine Officers Candidate School – or as she calls it “screamy summer camp.” It’s sort of like an all-inclusive Sandals Resort. You get your room, meals, drinks, plus many interesting activities and outings – plus thousands and thousands of push-ups. And to top it off, you’re nearly a Marine Corps officer when you’re done! We’re very proud of our Jessi and know she’s going to do great. In unrelated news, Henry reports in from Las Cruces, straight from his echoey bunker. He’d doing great in the new house.

AI Anywhere, Anyone?

Our main story this week concerns Dell’s integration of VMware and Bitfusion to provide “AI anywhere” type of infrastructure where any set of systems can get access to typically underutilized GPUs sitting anywhere on the network. This could mark the end of “GPU silos” in both enterprise and HPC data centers and lead to much better utilization of expensive GPU assets. The guys bat around the pros and cons of virtualization. Henry raises the point that not all applications will work right out of the box with this type of virtualization (or any virtualization, for that matter). The real key according to Henry is how much computation you need vs. how much data you need to move. So to justify the movement of data, the computational density of the job needs to be high. We kick these concepts back and forth and it’s a good and meaty discussion. Dan and Henry even violently agree a couple of times as we go through it. Amazing.

Reasons Why No One Should Ever be Online. Ever.

 Russian agents have been attacking a critical part of the Exim Email Transfer Agent – which is very bad. This could allow a ‘man in the middle’ style exploit of emails passing through these systems. Or highly targeted attacks on individual organizations. This is why I’m starting to convert back to fax.

Catch of the Week

Jessi:  Jessi’s catch of the week is, gasp, another podcast – and not ours! She heartily recommends that our listeners also listen to the Modern Figures podcast. Their motto:  A podcast elevating the voices of black women in computing. Radio Free HPC approved and certified, so you have our permission to listen.

Henry:  Several European academic supercomputers have been hijacked in order to run crypto mining. It is unknown how much crypto they mined or the value of it. The attackers were particularly sophisticated when it came to covering their tracks, making the systems look like there wasn’t anything running when they were, in fact, furiously running crypto routines. Crafty stuff.

Shahin:  Gives a shout out for Hot Chips, a virtual event this year that will be held later this August.  All of you who always wanted to attend and couldn't should take advantage of this. Either way, we'll probably do a post-show show to bring you the highlights of the event that's putting Silicon back into Silicon Valley.

Dan:  The US of A is back in space! Yay!

NSF, QIS Funding, But First...

18th Listener Awards!

Run-of-the-mill start as we introduce the team. Henry has quite a bit of echo since he’s now firmly ensconced in his rammed earth survival compound.

Big news this week! We finally received our 18th email in our first ever RadioFreeHPC email-to-win contest. First, let’s see what they win…

The first item in our Grand Prize bundle is a circa 1999 suede leather IBM S/390 laptop bag. It’s roomy at a generous 16”x14”, large enough to house the biggest 17” laptop or maybe 15 or 20 tablets. If that’s not enough room, it also expands an additional 4-5” on the bottom. There are compartments galore under the flaps and you’d better fill them up with soft foam since there’s really no padding around the laptop compartment.

The suede leather is a nice touch that adds weight to the bag, it’s not a lightweight in any sense of the word. We’d advise covering the bag if you’re going to be out in the weather, because the suede is sure to stain if it is exposed to water.

This bag is in brand new condition and has never been used. Ever.

The second piece of this cornucopia of delight is a IBM Mainframe 50th anniversary medallion. It’s a very light weight metal medallion housed in a stunningly clear plastic frame. Put it on your mantle at home and impress your friends and family with how important you must be to have such a keepsake.

The final gift is a cassette tape of an IBM Talk S/390 episode covering S/390 integrated solutions. If you still have a cassette player, this will provide minutes of mainframe tech talk, marketing tips and keys to closing that big deal.

So you want to know who won this amazing collection of swag? Listen to the show and find out, or follow us on Twitter and look a couple of weeks back!

Government Bills Aim to Up the Ante for Science

In the rest of the show we discuss some recent government news. First is that the US House is looking to devote an additional $1.25 billion over the next five years. But even bigger is the proposal to expand the US National Science Foundation by $100 beeelion – which is more than 4x the size of the existing organization. We discuss the implications of this and how this might change the game in terms of base research. There is also a bill to significantly dial up funding for Quantum Information Science. All good and the team s excited to see these moves and hopes they'll proceed swimmingly!

Reasons Why No One Should Ever be Online. Ever.

Brace yourselves, GitHub has been attacked! Developers and users alike unaware that they’re downloading malware when they’re getting their open source on. Ouch.

Catch of the Week

JessieCampaign Zero and Police Scorecard aim at reducing police violence.

HenryUK broadband performance is holding up in these virus-rampant times. Yay for the UK, great job.

DanSkinny gene discovered! Eat all you want and never gain weight. Is it true?

@HPC_Guru Speaketh! Kind of.

Our Guest Today is...

In this extraordinary episode of Radio Free HPC, the crew interviews the industry icon that is @HPC_Guru. This is the first time that anyone has been granted an interview with him and we’re proud to have been chosen for this honor.

We posed an even dozen questions and received very thoughtful responses, which we rendered out in a machine voice in order to fit our podcast format. In the interview, HPC_Guru tells us his top five cool things in HPC today, why he remains anonymous, where he thinks HPC hardware will be in 10 years and who he thinks will be the first to reach exascale. And that’s just four of our 12 questions!

We don’t have to tell you that @HPC_Guru is a legend in the industry, as is his Twitter account. He has more than 15,000 followers and has tweeted over 38,000 times. Just to put that in context, if his average tweet is 150 characters, then he’s tweeted 5.7 million characters. Or if you look at it as words, HPC Guru has beaten the hell out of Leon Tolstoy’s War & Peace. Tolstoy came up with a piddling 587,287 words in his novel while HPC Guru has written roughly 712,500 words – and HPC Guru has written about more difficult content. Supercomputing is much more complex than Napoleon’s invasion of Russia. While this is impressive, it’s not quite as many words/characters as Timothy Prickett Morgan writes in a typical year.

If you printed up HPC Guru’s tweets, the tome would come in at more than four pounds, and that’s single spaced. That’s as much as a high-end laptop, including the storage and maybe even the power brick. Looking for another metric? If @HPC_Guru printed out each of his tweets, two per sheet of 8.5 by 11 inch paper, and laid them end to end, it would stretch a little over 3.3 MILES.

Give this groundbreaking episode a listen, in fact, listen to it twice to get the full impact.

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.

A is for Ampere, Nvidia A100's Public Debut

NOTE:  The publication of this episode was delayed due to the untimely passing of our partner and pal Rich Brueckner. So what we’re announcing as "breaking news" isn’t so fresh today, but our takes on what NVIDIA’s new A100 processor brings to the table are still valid. 


Breaking News! This special edition of RadioFreeHPC takes a deep dive into NVIDIA’s spanking new A100 GPU – which is an impressive achievement in processor-dom. The new chip is built with a 7nm process and weighs in at a hefty 54 billion transistors and capped at 400 Watts. It sports 6,912 FP32 CUDA cores, 3,456 FP64 CUDA cores and 422 Tensor cores.
This 8th generation GPU, using what the company calls its Ampere technology, is a replacement for both their V100 GPU and Turing T4 processors, giving the company a single platform for both AI training and inferencing.
We talk about the specs of the A100, breaking down its game both in terms of typical HPC FP64 processing and FP32 (and lower precision) computing for AI workloads. On the HPC side, the new GPU seems to offer an across the board 25% speedup, which is substantial. But the A100 really shines when it comes to tensor core performance which the company reports at an average speed up of 10x on Tensor Core 32 bit vs. V100 FP32.
New features of the A100 include Sparsity (a mechanism that doubles sparse matrix performance), a much speedier NVLink (2x), and a hardware feature that allows the A100 to be partitioned into as many as 7 GPU instances to support individual workloads.
All in all, this is an amazing new processor, a behemoth large and hot, but so fast, chip that is heavily tilted towards new AI and Tensor workloads with a passing but welcome nod to 64-bit HPC apps.

Tribute to Rich Brueckner, 1962-2020

by Dan Olds



This is a tough blog to write for this RadioFreeHPC episode.

This is the episode where we say a final goodbye to our co-founder and comrade in arms Rich Brueckner. Rich passed away suddenly last week leaving us shocked and shaken. The whole genesis of RFHPC came out of Rich and I sitting around the press area of GTC 2012 and talking about what we could do to bring a little more life into the HPC community. We batted around several ideas but finally came up with the idea of a long-form podcast that would tackle every topic in tech – as long as it was big and fast. With that idea in mind, we recruited Henry Newman, started production, and the rest is history as they say.

We added Shahin Khan to our host lineup to add more technical heft and to give us increased flexibility to cover our travel schedules. But after nearly six years, Rich’s ultra-busy schedule didn’t allow him to continue working with us on RFHPC, but he remained a friend of the show, promoting it on his InsideHPC site. Our latest addition to our roster is rookie host Jessie Lanum, an outstanding university student who has added enthusiasm and a youthful viewpoint to our show.

In this episode, we pay tribute to Rich, sharing our own thoughts about him - plus the thoughts and memories from HPC community members. There are several funny stories in here, along with heartfelt  acknowledgement of the vital role Rich played in our HPC community. So please give a listen and share your thoughts and stories.

I’d also like to call your attention to the following links. These are shows that either feature Rich prominently or have us talking about Rich in depth. They really show his sense of humor, how highly we regarded him and his commitment to HPC. Take a look or listen, I think you’ll enjoy them….



RF-HPC Episode 18-1: This is our first holiday episode. In this show, Henry and I discuss the perfect Christmas gifts for Rich and make fun of his Apple addiction. Check out the videos on these picks, they’re funnier than the audio version.

RF-HPC Episode 18-2:  In this one, Rich and Dan talk about the perfect Christmas gifts for Henry. The picture of Henry as a Tibetan monk is one of Rich’s all-time favorites.

RF-HPC Episode 18-3:  To finish out this series, Rich and Henry talk about what they’d give me for Christmas.

Rich Brueckner


RF-HPC Episode 218:  A Hard Look at Santa’s Big Data Challenges

RF-HPC Episode 214:  Rich & Dan report on the CHPC South African conference, plus the CHPC cluster competition too!

Thank you for all the memories and all of your hard work, Rich. You did good for a lot of people.

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.

ColdQuanta Serves Up Some Bose-Einstein Condensate

The show starts with Dan, Jessi and Shahin in attendance. Henry is traveling from his old home base in Minnesota to his new command bunker in lovely Las Cruces, NM. Last we heard he was in Kansas City and making good time. We’re not sure how long we’re going to have to do without him as Comcast seems to be slow playing him on his internet installation timeline.

Why Freeze the Whole Room If you Just want a Frozen Atom?

Our big topic today is the quantum computing company ColdQuanta. It’s headed by an old pal of ours Bo Ewald and has just come out of stealth mode into the glaring spotlight of RadioFreeHPC. They have a unique approach to quantum computing, trapping atoms themselves to create Bose-Einstein Condensate. This is a fifth state of matter, which matters quite a bit. When you freeze a gas of Bosons at low density to near zero, you start to get macroscopic access to microscopic quantum mechanical effects, which is a pretty big deal. With the quantum mechanics start, you can control it, change it, and get computations out of it. The secret sauce for ColdQuanta is served cold, all the way down into the micro-kelvins and kept very locally, which makes it easier to get your condensate.

The company is focused on measurement and sensing but also mention straight computation, the latter like most of the other quantum competitors. They were the first company to put their quantum computer in space and the first to create Bose-Einstein Condensate while in orbit at the International Space Station.

Catch of the Week

Jessi:  Want to chill out and help NASA at the same time? Jessi has found a way with NeMO-Net, a game where users cruise through an animated ocean floor and classify coral structures. Your answers are then fed into NASA’s Pleiades supercomputer, which uses the data as fodder to improve it’s own identification prowess. It’s a great way to while away the hours during these Covid19 shut downs, right?

Shahin:  has two catches, the first is a celebration of IBM’s quant-iversary, marking the fourth anniversary of them having a quantum computer on the web – many happy returns to Big Blue. They’re also sponsoring a contest, see the web link for details.

In his second catch, Shahin shamelessly promotes his recent talk at the HPC AI Advisory Council virtual Stanford conference. He did a great job on covering just about every buzzword topic in the industry in only 30 minutes, well done.

Dan:  Dano likes fast things and seeing fast things get even faster. This is what attracted him to the story about ISV Risk Fuel and Microsoft’s Azure posting an article boasting a 20 million x speedup of derivative processing.  A 20 million times speedup of anything is pretty significant and they achieve this with a combination of 8 NVIDIA V100 GPUs (w/32GB memory each), InfiniBand and Risk Fuel’s amazing software. What’s great about this is that with this speed the model has complete fidelity with traditional calculations. In other words, you can speed all you like without any downside when it comes to accuracy – amazing stuff.

What Good Did It Do? Quite a Lot, and Quite the Story

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:

JessiGoogle’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!

Honeywell Traps, Zaps Ions for Science

Dan starts this episode with, as usual, an introduction of the cast. Henry reports that he’s only three weeks away from his epic move from Minnesota to Los Cruces, New Mexico.

Trapping Those Unruly Ions

We quickly move to our main topic:  Honeywell’s Trapped Ion Quantum computing initiative.  Shahin gives us a good overview of digital vs. analog and classical vs. quantum science (I recommend listeners white board out the quadrants he’s describing and their contents). The Honeywell system is in the ‘quantum-gate’ quadrant of Shahin’s model, suspending ions in space through magnetics and then hitting them with lasers to produce entanglement.

The Honeywell system is interesting because it is scoring well on the emerging Quantum Volume metric – showing very high fidelity for its qubit count. This system is the culmination of over 10 years of R&D and should be on the market later on this year.

Studying from Home

How does studying from home compare to working from home? Our second topic today is a dive into how universities are operating during the virus-related physical campus closings. Our own Jessi explains how her Purdue classes are now being conducted online with professors either video recording lectures or narrating slide decks. Some of her classes are truncated due to platform limits and tech problems. This is probably to be expected given the sudden move to online. There are practical considerations as well. Many students were on spring break when the lock downs went into place, so they don’t have their books or clothes with them. Jessi definitely does not think that online universities are the wave of the future. She strongly prefers the physical model where she can interact with students and professors. According to Jessi, nothing beats the physical model when it comes to higher ed.

Reasons Why No One Should Ever Be Online. Ever.

This week, Henry hips us to the fact that Chinese hackers may have been living in the guts of Linux since 2012. This is truly a chilling thought, as Linux runs a good portion of mission critical systems and almost all the cloud systems in the world. How big a threat is this? Listen to the pod to find out.

Catch of the Week

Jessi:  COBOL LIVES! The state of New Jersey is desperately looking for COBOL programmers to keep their creaky unemployment insurance system cranking along.

Henry:  hooked a big fish, but passed it over to Shahin who thinks it's pretty sublime.

Shahin:  landed Henry’s catch, which is a very rare film of the WW2 British code breakers hard at work at the legendary Bletchley Park site. Amazing stuff.

Dan:  a rare empty net week for Dano, sad, very sad.

AI in Science. When is it real?

We fire up the show with introductions and a little snippiness on Dan’s part. Henry reports that the weather in Minnesota is nearly human.

AI in Science

Jumping into our main topic, Shahin introduces an article from HPCwire interviewing Argonne’s Associate Laboratory Director Rick Stevens about how the DOE will be using AI in science. This is one of the biggest potential changes in our industry and well worth the investigation. But figuring out where AI fits into the traditional world of research and simulation is a difficult problem. Henry points out that nearly every grant proposal needs to include “AI” in order to get serious consideration.

We discuss Dan's Great HPC Road Trip* of national labs in 2018 and how nearly every lab is looking at using AI to inform their simulations and cut down on the brute force computing they’re doing now. Dan’s national lab interviews are here: Idaho National LabNCARNRELLos AlamosSandiaNERSCLawrence Livermore

There’s also a slight tangent where Dan talks about driving hundreds of miles out of his way to mess with Henry’s Las Cruces lot and future home. This resulted in an epic short film “The Haunting of Henry House” which is stuck in bureaucratic  approval cycles according to Henry.

RFHPC Hall of Fame?

We also discuss the possibility of founding a Radio Free HPC Hall of Fame, but discarded it when we realized that no one would want to be in it.

COVID-19

As the conversation continues, Dan brings up an article that discusses how COVID-19 might affect processor foundry revenues and demand. We are, as a group, underwhelmed by the analysis. Henry notes that he has seen a significant increase in the price of laptops when shopping for a graduation gift for his nephew. Henry has reportedly seen an increase of around 20% in prices since February.

Reasons Why No One Should Ever Be Online. Ever.

Hackers have stolen and ransomed AMD’s GPU test files, a dastardly act, but not surprising to see. They’re looking for $100 million to give the files back, while AMD has downplayed their importance and value.

Catch of the Week

Henry:  Another empty net week for our pal Henry
Shahin: How is the internet coping with all of the extra traffic caused by Covid19 isolation?
Jessi:   For the first time in recorded history, Jessi’s net is empty….sad.

SuperCatch

Dan:  has a SuperCatch! He does a promo of the inaugural episode of a new RadioFreeHPC segment. Suffice to say that RadioFreeHPC Studios has a brand new production of “Charles Babbage, His Life & Times,” a gripping radio drama that will engage your emotions from A-B.

Supercomputers Battle Corona

The conversation today begins with discussing how long it will take until Henry moves into his rammed earth Los Cruces bunker. For those of you keeping track at home, the correct answer was 41 days at the time of taping, which, by the time the podcast is out will probably be "a couple of weeks ago".

We quickly move on to discussing the Corona Virus, which started sharing the headlines with its handiwork COVID-19. What else is anyone talking about these days, right? We discuss how the supercomputing community has joined the fight and the impact on the battle against the virus.
We do our best to keep the conversation light, knowing that everyone out there is suffering from the virus – it’s the one thing we all have in common these days. We hope you enjoy the episode.

Catch of the Week:

Henry:  Hackers target medical field during Covid19 crisis, one of the crappiest things we’ve heard in a long time.
Shahin:  Tells us about a great paper title, “Software Defined Microarchitecture An Arguably Terrible Idea, but Certainly not the Worst Idea” as found on InsideHPC.
Jessie:  Discusses how Globus is offering free access for anyone working on the Covid19 Virus. Great job, Globus, way to pitch in.
Dan:  Shares his latest addiction, the ancient Asian game of Go. Here is an intro to the game and some puzzles to work on, get crackin’.

Climbing El Capitan? Details Detailed!

 Supercomputer Leaps to New Peaks

At the top of the show we discuss whether Indiana (where Jessi is located at Purdue) is in the heartland or not. We all agree that it is and, yes, Jessi sees Larry Bird all the time.

Getting into the heart of the episode, Dan talks about the briefing he received on the new Lawrence Livermore El Capitan system to be built by HPE/Cray. This new $600 million system will be fueled by the AMD Genoa processor coupled with AMD’s Instinct GPUs. Performance should come in at TWO 64-bit exaflops peak, which is very, very sporty. The new box (more like a room) will be 10x faster than today’s fastest supercomputer and faster than the top 200 supercomputers in the world – combined.

As the show continues, we talk about the specifics of the system and components. Henry make the unfortunate mistake of bringing up IEEE floating point and sending Dan into a mini-rant. Back to the show, the system should require somewhere close to 30MW worth of electricity, which is much lower than the nearly 60MW predicted just a year or so ago. Not surprisingly, the system will be liquid cooled, but not, as we speculate, cooled by Slushy machines. We have a tremendous tech talk around the varying aspects of the machine and AMD’s great progress in clawing their way back into the market. Well worth a listen.

Why No One Should Ever Be Online. Ever.

In this edition, Henry talks about how an ultrasonic hack can make your phone vulnerable to pownership. Just sending the exact right frequency of sound to a phone sitting on a solid object might be enough to unlock it and let a miscreant get at all of your goodies. Yikes!

Catch of the Week

Jessi:  Astronaut applications have opened up again! If you ever wanted to go to space, this might be your chance. You’ll want to have a strong science and computing background – plus hero or heroine good looks wouldn’t hurt either.

Shahin:  Discusses AMD vs. NVIDIA GPU comparative shipment figures from 4Q2019.

Henry:  Net is empty, ouch.

DanBees can count to six, which is hugely disquieting. If bees can do math, we might be doomed. Maybe this is why beehives are hexagonal?

One Big Debate over OneAPI

For RF-HPC 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.

Let's Learn Deeply about Extreme Weather

This week we have Dan, Jessi, and Shahin on the call. Henry is off in Los Cruces overseeing construction of what can only be called a bunker. Why? Its main feature is 21-inch rammed earth walls, guaranteed to withstand withering heat waves, cold snaps, and probably any high caliber round. We speculate on the exact configuration of the home, wondering if Henry is running wild with the rammed earth and concrete theme, with concrete chairs and tables, plus rammed earth interior walls.

Applying Deep Learning to Extreme Weather

Dan deftly moves us on to the main topic of this show, how researchers are using supercomputers to apply deep learning to extreme weather. A research team from Rice University utilized three supercomputers (TACC’s Stampede 2, Wrangler, and Pittsburg Supercomputing Center’s Bridges system) to see if data on heat waves and cold spells could be predicted by analysis of atmospheric circulation and prior surface temperature. The results of these tests indicated that this deep learning approach is more accurate at predicting extreme weather.

In the call, we discuss the computational difficulty of weather forecasting and the use case that the Rice researchers are testing. This promising research can pay great dividends in terms of  giving early warning to hazardous weather, saving crops and perhaps saving lives in the process.  As promised in the podcast, here’s a link to the paper. We also have a short discussion of what motivates Dan to read a particular paper and what turns him off. Jessi’s main standard in papers is that it has to be able to be printed in black and white and remain legible and understandable. So if you want to attract Jessi’s attention for your paper, make sure your charts don’t use color.

Things You Think You Know, But Maybe Don't.

The question this week is why Cray computers were horseshoe shaped.  One of the reasons was wire length and this shape puts the components closely together to reduce the length of the wires needed to connect them. It also gave them enough room for a person to get their hands inside to weave the wires. So the key was minimal, uniform, and accessible wire length. There are also a couple of other explanations, one is that it gave room for the liquid cooling pipes necessary to cool the box, another is that the system forms a capital “C” shape, which stands for, of course, Cray.

Catch of the Week



Henry: is away this week. (We know some of you don't read this all and come straight here!)

Jessi:  Tells us that the US might want to take a close look at Estonia as a model to overcome cybersecurity. The country has put together a civilian cybersecurity force and instituted mandatory cyber classes in schools. This is a response to massive cyberattacks launched against Estonia in 2007 that took down much of their digital infrastructure for weeks.

Shahin:  Discusses how Justine Haupt came up with a way to keep her cell phone from distracting her – she built a rotary dial interface for it. Along with helping save her from using the most time-wasting features on her phone, it will also confound an entire generation of folks who have never seen a rotary phone dialer. Justine also is working in robotics and has a page of her inventions and thoughts.

Dan:  Brings up a story about a man convicted of murder mainly on the basis of DNA evidence, although that evidence was shaky, mainly saying that they couldn’t exclude him. His case was reopened by the Innocence Project who reached out to a company called Cybergenetics for further analysis. Cybergenetics ran samples through their 170,000 line AI algorithm and found that there was zero chance that the convicted man’s DNA was present in the sample. So the man will be released, which is great. The problem is that the Cbyergenetics code is a black box and the company, citing competitive advantage, will not release the code.  How should we deal with situations like this in the future?

Slingshotting to Exascale, It's Hot!

At the top of this episode, Henry notes that the temperature in his city will be touching -15F, which is plenty cold. However, it’s very good overclocking weather as Dan and Shahin point out. Not quite quantum weather, unfortunately.

Cray Slingshot Interconnect

We quickly get to the main topic of the day, an examination of HPE/Cray’s Slingshot interconnect. It’s Ethernet on HPC steroids and will be the interconnect of choice for their upcoming slate of Exascale systems. Slingshot includes a bunch of HPC enhancements while maintaining compatibility with existing Ethernet devices and protocols. Cray has designed a new Ethernet superset of features that includes smaller headers, support for smaller message sizes, plus other features aimed at cutting Ethernet latency and improving performance on HPC-oriented interconnect tasks. At the heart of this new interconnect is their innovative 64 port switch that provides a maximum of 200 Gb/s per port and can support Cray’s enhanced Ethernet along with standard Ethernet message passing. It also has advanced congestion control and quality of service modes that ensure that each job gets their right amount of bandwidth.
The architecture can scale to an astounding 279,040 endpoints, which is, as we note, “a lot of endpoints.” We also kick around the possibility that HPE/Cray might sell the interconnect as a standalone for use with competitive gear.

Cray Slingshot Interconnect

As mentioned on the call, the chips on this switch run so hot that they need liquid cooling – a first for interconnect processors. We also discuss the rising heat load coming from new CPUs and particularly ASICs and how network design can greatly impact costs. Listen to the show to learn about more, it’s a good and meaty discussion.

Why Nobody Should Ever be Online. Ever.

Henry’s latest reason why we need to abandon the internet cracks us all up. What’s so funny? It’s that the Phillips smart lightbulbs need a firmware upgrade in order to prevent miscreants from pwoning your entire network. No kidding, it’s true. And hilarious. Here’s the link. This has Henry thinking about how to protect his new home from war flying drones. He’s looking into drone killing home-based air defense systems or perhaps a whole-home Faraday cage.

Catch of the Week



Henry:  Another security related story, this time about low level exploits in the Cisco Discovery Protocol (CDP) that can expose tens of millions of devices to internet troublemakers. This is highly disturbing since there is so much Cisco gear out there and the fix relies on users updating their firmware to plug the holes. Ouch.

Jessi:  Brings athletics into the podcast, which is the cause of some banter about how totally un-athletic the rest of us are (with the exception of Jessi, of course). Nike is using big time computation to 3D print their new uppers to give athletes the ultimate advantage in shoe performance.

Shahin:  Alerts us to a comprehensive review of AMD’s Ryzen Threadripper 3990X, the first CPU in the world to sport 64 cores. This CPU is currently the top of AMD’s line and is just another signpost signaling AMD’s resurgence. Welcome back, AMD.

Dan:  As we covered in a prior episode, Microsoft had the fantastic idea of forcing their corporate Office 365 users to have Microsoft’s Bing installed as their default search engine, using an update to accomplish this task. Well, the users have spoken and their voice was heard loud and clear in Redmond. The company is retreating from their forced ‘upgrade’ to Bing and back pedaling with all due speed. Hee. Hee.

Coronavirus

The show starts with our traditional lull, which always follows our initial introductions – when no one knows who should speak first, or prefer not to. However, we quickly regain our footing and get to the major topic of the day:  the coronavirus or COVID-19 as the doctors have dubbed it.

Shahin started out the conversation with a quick point about how supercomputing can help predict and track the progress of the disease. He also wonders about the economic effect on the tech business as inventories dry up while producers are sidelined by the virus. Dan puts out a sunny prediction that the entire medical infrastructure of the world is now focused on this virus and that we’ll surely see a cessation of the virus, aided by spring weather. Henry talks about how everything is interconnected todays global economy and how an incident in one geography can have ripple effects everywhere else. Jessi brings up the point that even if there was a vaccine, it would be difficult to get everyone vaccinated in a timely manner.

The team discusses how this might be a very good argument for diversification of supply chains in order to ensure supply of critical good. Jessi and Dan counter that having many smaller suppliers is less efficient than having few large-scale suppliers, thus, even if more suppliers were spread out geographically, competitive pressure would soon force them to consolidate in order to be competitive.

Why Nobody Should Ever be Online. Ever.

Henry brings up an article that discusses how only THREE of every 100,000 cyber-crimes are ever prosecuted, a shocking stat no matter how you look at it.

Catch of the Week



Jessi:  The Pentagon is requiring defense contractors to be cyber-security certified before they can take on new contracts. Definitely a step in the right direction.

Henry:  Comes up short this week due to spectacular snowfall at, and possibly in, his current home.

Shahin:  A book, The History of Fortran, has captured Shahin’s interest this week. In another catch, Shahin lauds AMD’s burgeoning strength in the HPC market, which is still building and should continue for some time into the future. Henry sounds a cautionary note about how AMD has to continue to execute and can’t whiff on the next generation of chips. Dan points how out AMD was first to 64 bit and first to multiple cores, which led to their first big market success over Intel, but how the company fumbled the ball later on and faded away.

Dan:  Avast Antivirus, developer of the free Avast antivirus software, was caught selling customer browser data, reinforcing the fact that nothing is really free in the world today. If you’re not paying for a product, then you ARE the product. It also reinforces Dan’s belief that if the software is free, it’s a virus.

Faster Weather, Pizza, Tires

And High Powered Radio Towers, too

The show starts out in the usual way with check ups on the health and happiness of our hosts. Jessi finished a 50-mile race over the weekend, which is admirable, particularly when you consider she was on foot.

With a reasonable decent segue, Dan moves the conversation to the topic of this show:  the shiny new ECMWF (European Centre for Medium-Range Weather Forecasts) supercomputer. This new system will give them roughly 5x more compute power than their current system. The new box is an Atos BullSequana XH2000AMD fueled by high-end AMD 7742 Epyc processors, which will be the most powerful weather computer in the world. During the conversation we look at the history of ECMWF vendors, discuss the implications on weather forecasts given the power of this new system and the computational difficulties inherent in weather prediction.

Why Nobody Should Ever be Online. Ever.

This week, Henry tells us about the Microsoft 250 million customer records exposure, but it’s a head fake! Henry explains how this is actually an example of how a company should handle an exploit and how this one wasn’t very bad. The verdict? Clickbait. But still stay offline.

Catch of the Week



Jessi:  Dominos is using GPUs and AI to drive their production and make their deliveries more efficient. Very cool.

Shahin:  Pirelli is making a cyber tire that is sensor enabled and can communicate road conditions to other tires/cars via a 5G network.

Shahin dips into his net again to highlight how a fantastically ambitious man built a radio station in Ohio that went from 50 watts to 500 watts, 50k watts, and eventually to 500k watts. See the video in the link and marvel at the ambition, work, and complexity.

Henry:  From empty net to a catch that will make Shahin’s catch obsolete, Henry makes a last second save with his story about how contact lenses will give us augmented reality and let us see road temperatures better than our tires will.

Dan:  Relates his triumphant but ultimately tragic drone lessons. Henry and Dan relate how they’ve both suffered grievous injuries at the hands of a .49 Cox gas engine.

ZFS, AI for System Design, Power in GCE

Surprise! It's Snowing in Minnesota

The show starts on a combative note with Henry refusing to discuss how much snow is arrayed around his house. Dan shares his dream running a snowblower and Henry offers up his house but doesn’t offer airfare, which, assumedly, would be a deal breaker for the ever-cheap Dan Olds.

ZFS

With no big news in the industry this week, it’s a grab-bag show covering various topics. Shahin is up first with his discussion of  Linus Torvals’ dissing the ZFS file system. Henry weighs in on the evolution of ZFS and how his opinion of ZFS has changed over the last decade or so. Both Shahin and Henry feel ZFS is unique and highly useful and that maybe Linus isn’t up on current ZFS capabilities. Dan brings up the licensing issue with ZFS, in the context of Oracle typically acting like a rabid dog in defense of their intellectual property. In further conversation, Shahin makes the brilliant point that “Data is Data” to the confusion and delight of the others.

AI to Help Design Systems

Dan brings up the topic of machine learning being use for computer architecture design. Shahin is a bit skeptical and has several questions. Henry chips in with some comments about how this will probably aid app-specific hardware design. Dan then relates this article to another story about how MIT is using machine learning to predict how code will perform on a processor. Shahin states his belief that he's dubious about many of today’s proposed use cases for AI. After some coaching from Dan, Shahin is moved to a neutral position, maybe.
As a tangent, we discuss benchmarking and speculating with SPECint and SPECfp to figure out competitive performance.

More Power to GCE

Shahin then brings up a story about Google bringing IBM’s Power systems into their cloud, which leads to a brief discussion of why they’re doing it and what types of applications will be supported.

Why Nobody Should Ever be Online. Ever.

Henry Newman’s Reasons Why No One Should Ever Be Online. Ever:  in this week’s installment, Henry discusses how an online organization was hosting 56 million records of US citizens, including names, addresses, etc., in the open. Ouch.

Catch of the Week



Jessi:  her net is empty and there’s nothing on the hook. It’s her first week back in school, so we can cut her some slack this time. We do make the announcement that Jessi is now part of the RadioFreeHPC team as a co-host, which is pretty cool. We also discuss that one requirement for the position is that we get to monitor her transcripts, starting in high school. We’ll analyze major trends and developments in a comprehensive spreadsheet that will be posted online at some point in the distant future. Dan demurs when asked to show his transcripts.

Shahin:  Discusses LEO Labs, a company that tracks items in space and evaluates the probability of collisions. The company analyzes as many as 800,000 potential collision scenarios per day – wow – that’s a lot of number crunching. Shahin explains how they do this and the results.

Henry:  Not only has nothing in the boat, he didn’t even get a nibble this week.

Dan:  Eulogizes the late, great, Mira supercomputer. After eight long years, Mira will be laid to rest later on this year. Mira is one of the last IBM Blue Gene/P systems and propelled the system to the third spot on the TOP500 list. It was the go-to system for ‘one in a billion’ simulations, drug discovery, and particle physics to name a few. It was a great system and it will be missed. Job well done, Mira, job well done.

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, Quantum, Quantum


 This episode was recorded back in 2019 but then the holiday episode had to go out during holidays and cut in line, messing up the cogs of the well-oiled machine that is the RFHPC production process. Regardless, the episode starts out with Henry being cranky. It also ends with Henry being cranky. But between those two events, we discuss quantum computing and Shahin’s trip to the Q2B quantum computing conference in San Jose. His walkaway, as someone else put it, and he quotes: “Quantum computing is overhyped and underestimated.”

Not surprisingly, there is a lot of activity in quantum, with nearly every country pushing the envelop outward. One of the big concerns is that existing cryptography is now vulnerable to quantum cracking. Shahin assures us that this isn’t the case today and is probably a decade away, which is another way of saying nobody knows, so it could be next week, but probably not.

We also learn the term “NISQ” which is a descriptive acronym for the current state of quantum systems. NISQ stands for “Noisy Intermediate Scale Quantum” computing. The conversation touches on various ways quantum computing is used now and where it’s heading, plus the main reason why everyone seems to be kicking the tires on quantum:  the fear of missing out.

It’s a very exciting area, but to Shahin, it seems like how AI was maybe 8-10 years ago, so still early days.

Why Nobody Should Ever be Online. Ever.

Henry lays out a dizzying scenario where hackers contact a person, telling them that their credit card is about to be used by an unauthorized party and advising them to call the police. When the person calls the police, the hackers intercept the call and, while pretending to be the authorities, extract personal details, credit card numbers, etc. This is possible because the hackers have taken over the telephone switch. Ouch, scary stuff.

But to finish out the year on a high note, Henry touches on reasons why people should be online, which was, well, nice.

Things You Think You Know, But Maybe Don’t.

In keeping with the theme of the show, Jessi asks for a quickie intro into quantum computing, why it’s such a big deal, and how it will really be used. Shahin obliges with a discussion of a vast array of quantum stuff, even including a reference to Schrodinger’s half-dead cat. He also discusses how quantum can provide exponential speed ups over traditional computing and the promise of quantum in the future.

Catch of the Week

Dan has managed to catch the team catching their catch:




Henry’s net was empty this time.

Jessi:  Brings up how Emotet malware hackers are using high-school environmental activist Greta Thunberg as a lure to infect users with Emotet and other malicious software. The hook is in the form of an attachment, “Support Greta Thunberg.doc”, which, when opened, will launch a malicious macro that downloads the Emotet Trojan and executes it. Nasty stuff. https://www.bleepingcomputer.com/news/security/emotet-malware-uses-greta-thunberg-demonstration-invites-as-lure/

Shahin:  Never one to leave well enough alone, Shahin brings up quantum computing yet again by discussing a quantum comic strip (Saturday Morning Breakfast Cereal) that does a great job of explaining quantum concepts in cartoon form. What’s next? Using sock puppets to explain HPC? http://www.smbc-comics.com/comic/the-talk-3

Dan:  In the interests of time, Dan skips over his lame Catch of the Week.
