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.
