Nvidia's Huang Says His AI Chips Are Improving Faster Than Moore's Law
Posted by msmash on Wednesday January 08, 2025 @10:20AM from the pushing-the-limits dept.

Nvidia's AI chips are advancing faster than Moore's Law, the semiconductor industry's historical performance benchmark, according to chief executive Jensen Huang. "Our systems are progressing way faster than Moore's Law," Huang told TechCrunch. Nvidia's chips have improved thousand-fold over the past decade, outpacing Moore's Law's prediction of doubled transistor density every year, Huang said. He adds:

We can build the architecture, the chip, the system, the libraries, and the algorithms all at the same time. If you do that, then you can move faster than Moore's Law, because you can innovate across the entire stack.

[...] Moore's Law was so important in the history of computing because it drove down computing costs. The same thing is going to happen with inference where we drive up the performance, and as a result, the cost of inference is going to be less.

US Unveils El Capitan, World's Fastest Supercomputer, For Classified Tasks
Posted by msmash on Friday January 10, 2025 @11:50AM from the arms-race dept.

The world's most powerful supercomputer, capable of 2.79 quintillion calculations per second, has been unveiled at Lawrence Livermore National Laboratory in California, designed primarily to maintain the U.S. nuclear weapons stockpile and run other classified simulations. The $600 million system, named El Capitan, consists of 87 computer racks weighing 1.3 million pounds and draws 30 megawatts of power.

Built by Hewlett-Packard Enterprise using AMD chips, it operates alongside a smaller system called Tuolumne, which ranks tenth globally in computing power. "While we're still exploring the full role AI will play, there's no doubt that it is going to improve our ability to do research and development that we need," said Bradley Wallin, a deputy director at the laboratory.

Three New Superconductive Materials Were Discovered in 2024
Posted by EditorDavid on Sunday January 12, 2025 @01:56PM from the current-events dept.

"This year, superconductivity — the flow of electric current with zero resistance — was discovered in three distinct materials," reports Quanta magazine. "Two instances stretch the textbook understanding of the phenomenon. The third shreds it completely...."

After four years of reserch a team at Columbia assembled a "two-sheet device, cooled it down, and watched it superconduct..." A lab at Cornell found "a species of superconductivity that no one had seen coming." And then "Over the summer, a graphene device produced a mythical form of superconductivity:

The discoveries stem from a recent revolution in materials science: All three new instances of superconductivity arise in devices assembled from flat sheets of atoms. These materials display unprecedented flexibility; at the touch of a button, physicists can switch them between conducting, insulating, and more exotic behaviors — a modern form of alchemy that has supercharged the hunt for superconductivity. It now seems increasingly likely that diverse causes can give rise to the phenomenon. Just as birds, bees and dragonflies all fly using different wing structures, materials seem to pair electrons together in different ways. Even as researchers debate exactly what's happening in the various two-dimensional materials in question, they anticipate that the growing zoo of superconductors will help them achieve a more universal view of the alluring phenomenon...

[C]ustomizable 2D devices had freed them from the drudgery of designing, growing, and testing new crystals one by one. Researchers would now be able to quickly re-create the effects of many different atomic lattices in a single device and find out exactly what electrons are capable of. The research strategy is now paying off. This year, physicists found the first instances of superconductivity in 2D materials other than graphene, along with a completely novel form of superconductivity in a new graphene system. The discoveries have established that the earlier graphene superconductors mark just the outskirts of a wild new jungle...

The experimentalists are amassing a treasure trove of data for theorists to explain. [Cornell's superconductivity-discovering researchers] Mak and Shan hope that this abundance will let theorists predict ways to create superconductivity that experiments can confirm. That would demonstrate a true understanding of the phenomenon, which would mark both an academic achievement and a key step toward designing materials for revolutionary new technologies.

The article points out that already, superconductivity has "enabled the development of MRI machines and powerful particle colliders.

"If physicists could fully understand how and when the phenomenon arises, perhaps they could engineer a wire that superconducts electricity under everyday conditions rather than exclusively at low temperatures, as is currently the case. World-altering technologies — lossless power grids, magnetically levitating vehicles — might follow."

Will Nvidia Spark a New Generation of Linux PCs?
Posted by EditorDavid on Sunday January 12, 2025 @08:07PM from the sparking-speculation dept.

"I know, I know: 'Year of the Linux desktop ... yadda, yadda'," writes Steven Vaughan-Nichols, a ZDNet senior contributing editor. "You've heard it all before. But now there's a Linux-powered PC that many people will want..."

He's talking about Nvidia's newly-announced Project Digits, describing it as "a desktop with AI supercomputer power that runs DGX OS, a customized Ubuntu Linux 22.04 distro."

Powered by MediaTek and Nvidia's Grace Blackwell Superchip, Project DIGITS is a $3,000 personal AI that combines Nvidia's Blackwell GPU with a 20-core Grace CPU built on the Arm architecture... At CES, Nvidia CEO Jensen Huang confirmed plans to make this technology available to everyone, not just AI developers. "We're going to make this a mainstream product," Huang said. His statement suggests that Nvidia and MediaTek are positioning themselves to challenge established players — including Intel and AMD — in the desktop CPU market. This move to the desktop and perhaps even laptops has been coming for a while. As early as 2023, Nvidia was hinting that a consumer desktop chip would be in its future... [W]hy not use native Linux as the primary operating system on this new chip family?

Linux, after all, already runs on the Grace Blackwell Superchip. Windows doesn't. It's that simple. Nowadays, Linux runs well with Nvidia chips. Recent benchmarks show that open-source Linux graphic drivers work with Nvidia GPUs as well as its proprietary drivers. Even Linus Torvalds thinks Nvidia has gotten its open-source and Linux act together. In August 2023, Torvalds said, "Nvidia got much more involved in the kernel. Nvidia went from being on my list of companies who are not good to my list of companies who are doing really good work." Canonical, Ubuntu Linux's parent company, has long worked closely with Nvidia. Ubuntu already provides Blackwell drivers.

The article strays into speculation, when it adds "maybe you wouldn't pay three grand for a Project DIGITS PC. But what about a $1,000 Blackwell PC from Acer, Asus, or Lenovo? All three of these companies are already selling MediaTek-powered Chromebooks...."

"The first consumer products featuring this technology are expected to hit the market later this year. I'm looking forward to running Linux on it. Come on in! The operating system's fine."

Starlink's Satellite Internet is Cheaper than Leading ISPs in Five African Countries
Posted by EditorDavid on Sunday January 12, 2025 @10:34PM from the down-in-Africa dept.

"In at least five of the 16 African countries where the service is available, a monthly Starlink subscription is cheaper than the leading fixed internet service provider," reports Rest of World.

"Starlink, launched in 2019 by Elon Musk's SpaceX, has become the leading satellite internet provider in the world."

Now available in more than 100 countries, Starlink can also be a relatively affordable option for users trying to log on in countries with limited internet service providers... A Rest of World analysis indicates that in at least five of the 16 African countries where the service is available, a monthly Starlink subscription is cheaper than the leading fixed internet service provider... [Kenya, Ghana, Zimbabwe, Mozambique, and Cape Verde — though not including the upfront costs of Starlink hardware.]

Historically, internet connections around the globe have typically been enabled by ground-based internet service providers using fiber-optic cables and mobile base stations. But in many parts of the world, that infrastructure is sparse or nonexistent. "This is where satellite providers come in," said Nitinder Mohan, a computer science professor at the Delft University of Technology in the Netherlands who has studied Starlink's performance around the world. "I can be in the middle of a forest and, if I have a direct view of the sky, I can get my internet connectivity," he told Rest of World. "Regions which are previously underconnected — where there was no way of getting internet connectivity to them — now with these satellites, you can actually enable that...." According to the latest figures by the International Telecommunication Union, a U.N. agency focused on information and communication technologies, 38% of the population in Africa uses the internet, compared to 91% of Europe...

Since launching in Kenya in July 2023, Starlink has disrupted the existing internet service provider industry. Starlink offers high connectivity speeds and wide availability in remote areas, along with dramatically lower prices. The company also introduced a rental option... Starlink has become so popular in Kenya that the company paused new subscriptions in major cities in early November due to network overload. The company plans to deploy more infrastructure in Nairobi and Johannesburg in order to bring more people online, said Mohan, the computer science professor at Delft University.

Starlink is less than half the cost of the leading ISP in Kenya Ghana, and especially in Zimbabwe (where the difference is dramatic):

Starlink: $30
Leading ISP in Zimbabwe: $633.62

Now in Kenya legacy telecom providers like Safaricom "have responded by lowering prices and increasing internet speeds," according to the article. The head of the research wing of the Global Systems for Mobile Communications Association even told Rest of World ISPS are also developing their own satellite networks (like Vodacom's partnership with satellite mobile network AST SpaceMobile) — though ironically, AST SpaceMobile launched its first satellites with the help of SpaceX.

Neuralink Implants Third Brain Chip. Plans '20 or 30' This Year, Eventually 'Blindsight' Devices
Posted by EditorDavid on Monday January 13, 2025 @07:34AM from the in-the-chips dept.

"Neuralink Corp.'s brain-computer device has been implanted in a third patient," reports Bloomberg, "and the company has plans for about 20 to 30 more implants in 2025, founder Elon Musk said."

In an interview streamed on X.com, Musk says "We've got now three humans with Neuralinks implanted and they're all working well," according to The Times of India:

"We upgraded the devices, they'll have more electrodes, basically higher bandwidth, longer battery life and everything. So, expect 20 or 30 patients this year with the upgraded Neuralink devices...."

"[​O]ur next part will be Blindsight devices where even if somebody has lost both eyes or has lost the optic nerve, we can interface directly with the visual cortex in the brain and enable them to see. We already have that working in monkeys," Musk added.

AI Slashes Google's Code Migration Time By Half
Posted by msmash on Thursday January 16, 2025 @01:51PM from the ground-breaking-efficiency dept.

Google has cut code migration time in half by deploying AI tools to assist with large-scale software updates, according to a new research paper from the company's engineers. The tech giant used large language models to help convert 32-bit IDs to 64-bit across its 500-million-line codebase, upgrade testing libraries, and replace time-handling frameworks. While 80% of code changes were AI-generated, human engineers still needed to verify and sometimes correct the AI's output. In one project, the system helped migrate 5,359 files and modify 149,000 lines of code in three months.
