Asian Student Cluster Competition The ever-popular “calendar segment” is back (yes, that is us being sarcastic) as Dan describes his upcoming trip to Dalian, China for the Asian Student Cluster competition. 20 teams are expected to compete, mostly from mainland China, but also from Europe, South America and other parts of Asia. All of them… Read More »In-Memory, Caching, Persistence

Here's this week's synopsis. Black Holes VisualizedThe news of the cool visualization of an actual black hole leads to interesting issues in HPC land. Shahin is at pains to give credit where it is due while considering it as an achievement in data visualization not unlike many others before it. Yes, it's about a fascinating topic, but that's also not unlike many others in the past.But the team moves on to the real point: the size of the radio data that had to be collected and managed and processed to visualize it. 1.75 PB of raw data from each telescope meant a lot of physical drives that had to be flown to the data center. Henry leads a discussion about the race between bandwidth and data size, various companies’ plans to launch thousands of satellites to help get away from sneakernet, and the imminent arrival of 5G. We've discussed large scale data movement in previous episodes and think it's an important issue for HPC, AI, and Cloud.Catch of the Week Henry: That sneakernet discussion above is it for Henry this week. Shahin: Mapping Space Debris (video)LeoLabs is a company that maps objects in the low Earth orbit (LEO). The visdeo shows actual trajectories of 12,401 low Earth objects in space being tracked on August 24, 2017 by LeoLabs' phased array radars. Video loop shows approx 2 hours of data.Dan: Scientists put human gene into monkeys to make them smarter, human-likeMaking monkeys more smart and human-like, scientists have used gene-editing to insert human brain gene in a monkey. For the first time, a team of Chinese scientists made use of gene-editing techniques to make monkey brains more human-like. By the end, the monkeys, rhesus macaques, got smarter and had superior memories as compared to the unaltered monkeys.The team doubts this is a true story and that leads Shahin to his first rant on the show when he complains about previously reputable publications succumbing to clickbait. We're More Likely Than Not Living In A Computer Simulation, MIT Professor SuggestsAn MIT professor has said he believes it's "more likely than not" that we are living in some kind of simulated universe, given that we ourselves are not far away from being capable of creating hyper-realistic simulations ourselves.Yet another story that raises eyebrows.

We continue to want to make these introductions pretty brief here but not this time, apparently! Here's this week's synopsis. Nvidia GTC 2019 announcementsWe discussed the recent GTC conference. Dan has been attending since well before it became the big and important conference that it is today. We get a quick update on what was covered: the long keynote, automotive and robotics, the Mellanox acquisition, how a growing fraction of enterprise applications will be AI. In agreement with the message from GTC, Shahin re-iterates his long-held belief that the future of enterprise applications will be HPC and once again asserts that AI as we know it today is a subset of HPC. Not everyone agrees. Henry brings up varying precisions in AI and a discussion ensues about what is HPC. There seems to be agreement that regardless of what label you put on it, it is the same (HPC) industry and community that is driving this new trend. And that led to a discussion of selling into the enterprise and the need for new models and vocabulary and such. Speaking of varying precision, there is also Nvidia's new automatic mixed precision capability for Tensorflow and there is a bit of discussion on that. China plans multibillion dollar investment in supercomputingOn the heels of the Aurora announcement, there was news in the South China Morning Post that the top spot in supercomputing is something the country is investing in. No surprise, but interesting to see, and consistent with the general view that supercomputing drives competitive strength. Catch of the Week Henry: Facebook Stored Hundreds of Millions of User Passwords in Plain Text for YearsHundreds of millions of Facebook users had their account passwords stored in plain text and searchable by thousands of Facebook employees — in some cases going back to 2012, KrebsOnSecurity has learned. Facebook says an ongoing investigation has so far found no indication that employees have abused access to this data.Shahin: MIPS R6 Architecture Now Available for Open UseMIPS 32-bit and 64-bit architecture – the most recent version, release 6 – will become available Thursday (March 28) for anyone to download at MIPS Open web page. Under the MIPS Open program, participants have full access to the MIPS R6 architecture free of charge – with no licensing or royalty fees.Dan: Vengeful sacked IT bod destroyed ex-employer's AWS cloud accounts. Now he'll spent rest of 2019 in the clinkAn irate sacked techie who rampaged through his former employer's AWS accounts with a purloined login, nuking 23 servers and triggering a wave of redundancies, has been jailed.   Dead LAN's hand: IT staff 'locked out' of data center's core switch after the only bloke who could log into it dies'We can replace it but we have no idea what the config is on the device'Listen in to hear the full conversation.   Download the MP3 * Subscribe on iTunes * RSS Feed   Sign up for our insideHPC Newsletter

The team has an animated discussion about multicore scaling, how easy it seems to be to mislead AI systems, and some good sized catches of the week. A common thread is "data" as is often the case these days. We continue with making these introductions pretty brief here. This time, we include not only the links but also the first paragraph of the linked page as a block quote so you have a bit more information about what is discussed. Specialized Chips Won’t Save Us From Impending ‘Accelerator Wall’As CPU performance improvements have slowed down, we’ve seen the semiconductor industry move towards accelerator cards to provide dramatically better results. Nvidia has been a major beneficiary of this shift, but it’s part of the same trend driving research into neural network accelerators, FPGAs, and products like Google’s TPU. These accelerators have delivered tremendous performance boosts in recent years, raising hopes that they present a path forward, even as Moore’s law scaling runs out. A new paper suggests this may be less true than many would like.Nice 'AI solution' you've bought yourself there. Not deploying it direct to users, right? Here's why maybe you shouldn'tTop tip: Ask your vendor what it plans to do about adversarial examples. RSA It’s trivial to trick neural networks into making completely incorrect decisions, just by feeding them dodgy input data, and there are no foolproof ways to avoid this, a Googler warned today.Catch of the Week MyEquifax.com Bypasses Credit Freeze PINMost people who have frozen their credit files with Equifax have been issued a numeric Personal Identification Number (PIN) which is supposed to be required before a freeze can be lifted or thawed. Unfortunately, if you don’t already have an account at the credit bureau’s new myEquifax portal, it may be simple for identity thieves to lift an existing credit freeze at Equifax and bypass the PIN armed with little more than your, name, Social Security number and birthday. Announcing the Open Sourcing of Windows Calculator Today, we’re excited to announce that we are open sourcing Windows Calculator on GitHub under the MIT License. This includes the source code, build system, unit tests, and product roadmap. Our goal is to build an even better user experience in partnership with the community. We are encouraging your fresh perspectives and increased participation to help define the future of Calculator.Huawei Sues The US, Prodding It to Prove SuspicionsTHE WORLD'S LARGEST telecommunications-equipment company, China's Huawei, is suing the US government. But the suit isn't just about US law. It's part of Huawei's larger campaign to defend its role as a global provider of telecom gear amid fears that its technology is or could be used by the Chinese government for spying. In essence, Huawei is challenging the US government to prove its suspicions.Listen in to hear the full conversation.

Starting with this episode, we'll get a bit more efficient in describing the episodes. Please let us know if you prefer the long format. If you just subscribe on iTunes and never see these words, well, that tells us something too! In this episode, the team discusses AI, bias in AI, and just how real actual AI out there is. Ethics in AI, policy, legal framework are all big threads here. The trigger is the rather funny article Artificial Intelligence, You Know it isn’t real, yeah? Catch of the Week Shahin applauds NIST’s new Risk Management Framework, and especially the inclusion of supply chain security, something he and Henry keep bringing up. Henry discusses sensationalism in technical coverage by the example of an article that says blockchains can be hacked but lacks enough depth and thus fails to impress. As expected, Shahin comes to the defense of the technology, explaining that it depends on the consensus algorithm and participation, etc. not just blockchain per se. Discussion ensues about all manner of blockchains and the spectrum that is forming there with permissioned and permissionless chains.
