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.
