Intel has begun ferrying around 20 "super loads" across Ohio for the construction of its new $28 billion Ohio One Campus. The extensive planning and coordination required for these shipments are expected to cause road closures and delays during the nine days of transport. Tom's Hardware reports: Intel's new campus coming to New Albany, OH, is in heavy construction, and around 20 super loads are being ferried across Ohio's roads by the Ohio Department of Transportation after arriving at a port of the Ohio River via barge. Four of these loads, including the one hitting the road now, weigh around 900,000 pounds -- that's 400 metric tons, or 76 elephants. The super loads were first planned for February but were delayed due to the immense planning workload. Large crowds are estimated to accumulate on the route, potentially slowing it even further.

Intel's 916,000-pound shipment is a "cold box," a self-standing air-processor structure that facilitates the cryogenic technology needed to fabricate semiconductors. The box is 23 feet tall, 20 feet wide, and 280 feet long, nearly the length of a football field. The immense scale of the cold box necessitates a transit process that moves at a "parade pace" of 5-10 miles per hour. Intel is taking over southern Ohio's roads for the next several weeks and months as it builds its new Ohio One Campus, a $28 billion project to create a 1,000-acre campus with two chip factories and room for more. Calling it the new "Silicon Heartland," the project will be the first leading-edge semiconductor fab in the American Midwest, and once operational, will get to work on the "Angstrom era" of Intel processes, 20A and beyond. The Ohio Department of Transportation has shared a timetable for how long this process will take.

An anonymous reader quotes a report from TechCrunch: A Finnish startup called Flow Computing is making one of the wildest claims ever heard in silicon engineering: by adding its proprietary companion chip, any CPU can instantly double its performance, increasing to as much as 100x with software tweaks. If it works, it could help the industry keep up with the insatiable compute demand of AI makers. Flow is a spinout of VTT, a Finland state-backed research organization that's a bit like a national lab. The chip technology it's commercializing, which it has branded the Parallel Processing Unit, is the result of research performed at that lab (though VTT is an investor, the IP is owned by Flow). The claim, Flow is first to admit, is laughable on its face. You can't just magically squeeze extra performance out of CPUs across architectures and code bases. If so, Intel or AMD or whoever would have done it years ago. But Flow has been working on something that has been theoretically possible -- it's just that no one has been able to pull it off.

Central Processing Units have come a long way since the early days of vacuum tubes and punch cards, but in some fundamental ways they're still the same. Their primary limitation is that as serial rather than parallel processors, they can only do one thing at a time. Of course, they switch that thing a billion times a second across multiple cores and pathways -- but these are all ways of accommodating the single-lane nature of the CPU. (A GPU, in contrast, does many related calculations at once but is specialized in certain operations.) "The CPU is the weakest link in computing," said Flow co-founder and CEO Timo Valtonen. "It's not up to its task, and this will need to change."

CPUs have gotten very fast, but even with nanosecond-level responsiveness, there's a tremendous amount of waste in how instructions are carried out simply because of the basic limitation that one task needs to finish before the next one starts. (I'm simplifying here, not being a chip engineer myself.) What Flow claims to have done is remove this limitation, turning the CPU from a one-lane street into a multi-lane highway. The CPU is still limited to doing one task at a time, but Flow's Parallel Processing Unit (PPU), as they call it, essentially performs nanosecond-scale traffic management on-die to move tasks into and out of the processor faster than has previously been possible. [...] Flow is just now emerging from stealth, with [about $4.3 million] in pre-seed funding led by Butterfly Ventures, with participation from FOV Ventures, Sarsia, Stephen Industries, Superhero Capital and Business Finland. The primary challenge Flow faces is that for its technology to be integrated, it requires collaboration at the chip-design level. This means chipmakers need to redesign their products to include the PPU, which is a substantial investment.

Given the industry's cautious nature and the existing roadmaps of major chip manufacturers, the uptake of this new technology might be slow. Companies are often reluctant to adopt unproven technologies that could disrupt their long-term plans.

Michael Larabel reports via Phoronix: Covered last week on Phoronix was a new patch from Intel that with tuning to the P-State CPU frequency scaling driver was showing big wins for Intel Core Ultra "Meteor Lake" performance and power efficiency. I was curious with the Intel claims posted for a couple benchmarks and thus over the weekend set out to run many Intel Meteor Lake benchmarks on this one-line kernel patch... The results are great for boosting the Linux performance of Intel Core ultra laptops with as much as 72% better performance. [...]

When looking at the CPU power consumption overall, for the wide variety of workloads tested it was just a slight uptick in power use and thus overall leading to slightly better power efficiency too. See all the data here. So this is quite a nice one-line Linux kernel patch for Meteor Lake and will hopefully be mainlined to the Linux kernel for Linux 6.11 if not squeezing it in as a "fix" for the current Linux 6.10 cycle. It's just too bad though that it took six months after launch for this tuned EPP value to be determined. Fresh benchmarks between Intel Core Ultra and AMD Ryzen on the latest Linux software will be coming up soon on Phoronix.

T2's open development process and the collection of exotic, vintage and retro hardware can be followed live on YouTube and Twitch.

Now Slashdot reader ReneR writes: Embedded T2 Linux is known for its sophisticated cross compile features as well as supporting all CPU architectures, including: Alpha, Arc, ARM(64), Avr32, HPPA(64), IA64, M68k, MIPS(64), Nios2, PowerPC(64)(le), RISCV(64), s390x, SPARC(64), SuperH, x86(64). But now it's going Desktop!

24.6 comes as a major convenience update, with out-of-the-box Windows application compatibility as well as LibreOffice and Thunderbird cross-compiled and in the default base ISO for the most popular CPU architectures.

Continuing to keep Intel IA-64 Itanium alive, a major, up-to-3x performance improvement was found for OpenSSL, doubling crypto performance for many popular algorithms and SSH.

The project's CI unit testing was further expanded to now cover the whole installation in two variants. The graphical desktop defaults were also polished -- and a T2 branded wallpaper was added! ;-) The release contains 606 changesets, including approximately 750 package updates, 67 issues fixed, 80 packages or features added, 21 removed and 9 other improvements.

Slashdot reader storagedude shared this report from The Cyber Express: A security researcher discovered an exploitable timing leak in the Kyber key encapsulation mechanism (KEM) that's in the process of being adopted by NIST as a post-quantum cryptographic standard. Antoon Purnal of PQShield detailed his findings in a blog post and on social media, and noted that the problem has been fixed with the help of the Kyber team. The issue was found in the reference implementation of the Module-Lattice-Based Key-Encapsulation Mechanism (ML-KEM) that's in the process of being adopted as a NIST post-quantum key encapsulation standard. "A key part of implementation security is resistance against side-channel attacks, which exploit the physical side-effects of cryptographic computations to infer sensitive information," Purnal wrote.

To secure against side-channel attacks, cryptographic algorithms must be implemented in a way so that "no attacker-observable effect of their execution depends on the secrets they process," he wrote. In the ML-KEM reference implementation, "we're concerned with a particular side channel that's observable in almost all cryptographic deployment scenarios: time." The vulnerability can occur when a compiler optimizes the code, in the process silently undoing "measures taken by the skilled implementer." In Purnal's analysis, the Clang compiler was found to emit a vulnerable secret-dependent branch in the poly_frommsg function of the ML-KEM reference code needed in both key encapsulation and decapsulation, corresponding to the expand_secure implementation.
While the reference implementation was patched, "It's important to note that this does not rule out the possibility that other libraries, which are based on the reference implementation but do not use the poly_frommsg function verbatim, may be vulnerable — either now or in the future," Purnal wrote.

Purnal also published a proof-of-concept demo on GitHub. "On an Intel Core i7-13700H, it takes between 5-10 minutes to leak the entire ML-KEM 512 secret key using end-to-end decapsulation timing measurements."

As reported by Jon Peddie Research, Nvidia now holds 88% of the GPU market after its market share jumped 8% in its most recent quarter. "This jump shaves 7% off of AMD's share, putting it down to 19% total," reports XDA Developers. "And if you're wondering where that extra 1% went, it came from all of Intel's market share, squashing it down to 0%." From the report: Dr. Jon Peddie, president of Jon Peddie Research, mentions how the GPU market hasn't really looked "normal" since the 2007 recession. Ever since then, everything from the crypto boom to COVID has messed with the usual patterns. Usually, the first quarter of a year shows a bit of a dip in GPU sales, but because of AI's influence, it may seem like that previous norm may be forever gone: "Therefore, one would expect Q2'24, a traditional quarter, to also be down. But, all the vendors are predicting a growth quarter, mostly driven by AI training systems in hyperscalers. Whereas AI trainers use a GPU, the demand for them can steal parts from the gaming segment. So, for Q2, we expect to see a flat to low gaming AIB result and another increase in AI trainer GPU shipments. The new normality is no normality."

An anonymous reader shares a report: Intel's fastest processors have included hyperthreading, a technique that lets more than one thread run on a single CPU core, for over 20 years -- and it's used by AMD (which calls it "simultaneous multi-threading") as well. But you won't see a little "HT" on the Intel sticker for any Lunar Lake laptops, because none of them use it. Hyperthreading will be disabled on all Lunar Lake CPU cores, including both performance and efficiency cores. Why? The reason is complicated, but basically it's no longer needed. The performance cores or P-Cores on the new Lunar Lake series are 14 percent faster than the same cores on the previous-gen Meteor Lake CPUs, even with the multi-thread-processing of hyperthreading disabled.

Turning on the feature would come at too high a power cost, and Lunar Lake is all about boosting performance while keeping laptops in this generation thin, light, and long-lasting. That means maximizing single-thread performance -- the most relevant to users who are typically focusing on one task at a time, as is often the case for laptops -- in terms of surface area, to improve overall performance per watt. Getting rid of the physical components necessary for hyperthreading just makes sense in that context.

An anonymous reader shares a report: A Chinese research team says it has uncovered a significant security flaw in processor design that could have a wide impact on China's booming domestic chip industry. China was relying on the structure of the world's largest open-source CPU architecture to build their own CPUs and bypass the US chip ban, and was paying attention to any weaknesses, they said. The issue was found in RISC-V, an open-source standard used in advanced chips and semiconductors. Compared with mainstream CPU structures -- such as X86 used by Intel and AMD --RISC-V offers free access and can be modified without restriction.

The flaw allows attackers to bypass the security protections of modern processors and operating systems without administrative rights, leading to the potential theft of protected sensitive information and breaches of personal privacy. The vulnerability was confirmed by the team of Professor Hu Wei at Northwestern Polytechnical University (NPU), a major defence research institute in Shaanxi province. The researchers are experienced in hardware design security, vulnerability detection and cryptographic application safety. It was first reported by the National Computer Network Emergency Response Technical Team/Coordination Centre of China (CNCERT) on April 24, and NPU gave further details in an official announcement on May 24.

Apollo Global announced today that it will acquire a 49% equity interest in Intel's manufacturing facility in Ireland for $11 billion, in a deal expected to close in the second quarter. The deal "would allow Intel to redeploy parts of its investment in the project to other parts of its business," reports Reuters. "Intel has invested $18.4 billion in the facility till date." From the report: Apollo will acquire the stake in the Fab 34 facility in Leixlip, Ireland, the U.S. chipmaker's first high-volume location for its Intel 4 manufacturing process using extreme ultraviolet lithography machines. The company announced plans in 2022 to build chip factories in Ireland and France as it seeks to benefit from easier European Commission funding rules and subsidies as the bloc looks to cut its dependence on U.S. and Asian supply. Intel will retain full ownership and operational control of Fab 34 and its assets.

Intel Chief Executive Officer Pat Gelsinger took the stage at the Computex show in Taiwan to talk about new products he expects will help turn back the tide of share losses to peers, including AI leader Nvidia. From a report: Intel showed its new Xeon 6 data center processors with more efficient cores that will allow operators to cut down the space required for a given task to a third of prior-generation hardware. Like rivals, from Advanced Micro Devices to Qualcomm, Intel touted benchmarks that showed its new silicon is significantly better than its existing options. AMD and Qualcomm's CEOs, in earlier Computex keynotes, used Intel's laptop and desktop processors to show how far ahead they are in certain aspects of technology.

Gelsinger took a direct shot at Nvidia CEO Jensen Huang's claim that traditional processors like Intel's are running out of steam in the age of artificial intelligence. "Unlike what Jensen would have you believe, Moore's Law is alive and well," he said, stressing that Intel will have a major role to play in the proliferation of AI as the leading provider of PC chips. "I think of it like the internet 25 years ago, it's that big," Gelsinger said. "We see this as the fuel that's driving the semiconductor industry to reach $1 trillion by the end of the decade."

An anonymous reader quotes a report from PCMag: Justin Long, the actor known for playing the Mac guy in Apple's mid-2000s ad campaign is once again switching sides -- this time to promote new Windows laptops from Qualcomm. Long appeared in a video that Qualcomm showed during its Computex keynote. To introduce the segment, CEO Cristiano Amon said Qualcomm captured video of a "very special person" preordering a Windows Copilot+ laptop built with a Snapdragon X Elite chip.

In the clip, we see Long typing on an Apple MacBook at home and getting annoyed by all the incoming notifications, which include warnings that his laptop only has a 1% battery life and is running out of disk space. Long types in a search for "Where can I find a Snapdragon-powered PC?" and then stares at the camera, looking a bit ashamed, before saying: "What? Things change." Amon then returned to the stage to tell the Computex audience: "Yes, things change." In 2021, Long starred in an Intel ad campaign to promote the company's Windows PCs.

AMD is reverting to a simpler, more traditional numbering scheme for its laptop processors, abandoning its recent complex "decoder ring" system. The new system for Ryzen AI laptop processors will use a three-digit model number to denote generation and SKU, aligning more closely with industry norms. Ars Technica reports: For its new Ryzen AI laptop processors, codenamed "Strix Point," AMD is still using the same broad Ryzen 3/5/7/9 number to communicate general performance level plus a one- or two-letter suffix to denote general performance and power level (U for ultraportables, HX for higher-performance chips, and so on). A new three-digit processor number will inform buyers of the chip's generation in the first digit and denote the specific SKU using the last two digits. In other words, the company is essentially hitting the undo button.

Like Intel, AMD is shifting from four-digit numbers to three digits. The Strix Point processor numbers will start with the 300 series, which AMD says is because this is the third generation of Ryzen laptop processors with a neural processing unit (NPU) included. Current 7040-series and 8040-series processors with NPUs are not being renamed retroactively, and AMD plans to stop using the 7000- and 8000-series numbering for processor introductions going forward. AMD wouldn't describe exactly how it would approach CPU model numbers for new products that used older architectures but did say that new processors that didn't meet the 40+ TOPS requirement for Microsoft's Copilot+ program would simply use the "Ryzen" name instead of the new "Ryzen AI" branding. That would include older architectures with slower NPUs, like the current 7040 and 8040-series chips.

Desktop CPUs are, once again, totally unaffected by this change. Desktop processors' four-digit model numbers and alphabetic suffixes generally tell you all you need to know about their underlying architecture; the new Ryzen 9000 desktop CPUs and the Zen 5 architecture were also announced today. It seems like a lot of work to do to end up basically where we started, especially when the people at AMD who make and market the desktop chips have been getting by just fine with older model numbers for newly released products when appropriate. But to be fair to AMD, there just isn't a great way to do processor model numbers in a simple and consistent way, at least not given current market realities [...].

British chip designer Arm expects to capture more than half of the Windows PC market within the next five years, CEO Rene Haas said in an interview. The company's optimism comes as Microsoft and its hardware partners gear up to introduce a new generation of AI-powered PCs running on Arm-designed chips, potentially reshaping the Intel-dominated industry. Haas attributed Microsoft's commitment to supporting Arm's technology through enhanced developer tools as a key factor in the anticipated market shift.

Last than two weeks after it was announced, "Windows enthusiasts have managed to crack Microsoft's flagship AI-powered Recall feature to run on unsupported hardware," reports The Verge. From the report: Recall leverages local AI models on new Copilot Plus PCs to run in the background and take snapshots of anything you've done or seen on your PC. You then get a timeline you can scrub through and the ability to search for photos, documents, conversations, or anything else on your PC. Microsoft positioned Recall as needing the very latest neural processing units (NPU) on new PCs, but you can actually get it running on older Arm-powered hardware.

Windows watcher Albacore has created a tool called Amperage, which enables Recall on devices that have an older Qualcomm Snapdragon chip, Microsoft's SQ processors, or an Ampere chipset. You need to have the latest Windows 11 24H2 update installed on one of these Windows on Arm devices, and then the tool will unlock and enable Recall. [...] You can technically unlock Recall on x86 devices, but the app won't do much until Microsoft publishes the x64 AI components required to get it up and running. Rumors suggest both AMD and Intel are close to announcing Copilot Plus PCs, so Microsoft's AI components for those machines may well appear soon. I managed to get Recall running on an x64 Windows 11 virtual machine earlier today just to test out the initial first-run experience.

Framework, a company known for its modular laptops, has announced a fourth round of iterative updates and upgrade options for its Framework Laptop 13. The upgrades include motherboards and pre-built laptops featuring new Intel Meteor Lake Core Ultra processors with Intel Arc dedicated GPUs, lower prices for AMD Ryzen 7000 and 13th-gen Intel editions, and a new display with a higher resolution and refresh rate.

The Core Ultra boards come with three CPU options, with prices starting at $899 for a pre-built or DIY model. Upgrading from an older Intel Framework board requires an upgrade to DDR5 RAM, and Framework charges $40 for every 8GB of DDR5-5600, which is above market rates. The new 13.5-inch display has a resolution of 2880x1920, a 120 Hz refresh rate, and costs $130 more than the standard display.

An anonymous reader shares a report: Similar to the GCC compiler dropping support for the Xeon Phi Knights Mill and Knights Landing accelerators a few days ago, Intel has also gone ahead and seen to the removal of Xeon Phi support for the LLVM/Clang 19 compiler. Since earlier this year in LLVM/Clang 18 the Xeon Phi Knights Mill and Knights Landing support was treated as deprecated. Now for the LLVM 19 release due out around September, the support is removed entirely. This aligns with GCC 14 having deprecated Xeon Phi support too and now in GCC 15 Git having the code removed.

An anonymous reader shares a report: For those of us who came of age in the early days of personal computing, the names "Intel 486" and "Windows XP" evoke a nostalgic whirlwind of memories. The 486 was the hot new CPU of the early 90s, while Windows XP became a household name and Microsoft's most popular OS over a decade later. But did you ever imagine these two icons of different eras could be merged into an unholy union? Well, start brushing off those vintage 486 rigs, because a modder has actually made it happen. Going by the name Dietmar on the MSFN forums, he has somehow managed to get Microsoft's beloved Windows XP running on the ancient 486 architecture.

It's worth mentioning that these two were never meant to coexist. The first 486 chips hit the market way back in 1989, while Windows XP landed over a decade later in 2001. The 486 represented a major breakthrough when Intel unveiled it in 1989. Packing over a million transistors, it remained Intel's primary x86 chip until the arrival of the Pentium in 1993. Such was the processor's longevity that Intel continued manufacturing it for embedded systems until 2007. Still, 486 systems were simply too underpowered to run XP, which needed at least a Pentium-class processor from the 586 generation - or any compatible chip that ran at 233MHz or higher. Meanwhile, the i486 could only do 133MHz. It also needed at least 64MB of RAM and at least 1.5GB of storage.

An anonymous reader quotes a report from Ars Technica: Microsoft is going all-in on Arm-powered Windows PCs today with the introduction of a Snapdragon X Elite-powered Surface Pro convertible and Surface Laptop, and there are inevitable comparisons to draw with another big company that recently shifted from Intel's processors to Arm-based designs: Apple. A huge part of the Apple Silicon transition's success was Rosetta 2, a translation layer that makes it relatively seamless to run most Intel Mac apps on an Apple Silicon Mac with no extra effort required from the user or the app's developer. Windows 11 has similar translation capabilities, and with the Windows 11 24H2 update, that app translation technology is getting a name: Prism.

Microsoft says that Prism isn't just a new name for the same old translation technology. Translated apps should run between 10 and 20 percent faster on the same Arm hardware after installing the Windows 11 24H2 update, offering some trickle-down benefits that users of the handful of Arm-based Windows 11 PCs should notice even if they don't shell out for new hardware. The company says that Prism's performance should be similar to Rosetta's, though obviously this depends on the speed of the hardware you're running it on. Microsoft also claims that Prism will further improve the translation layer's compatibility with x86 apps, though the company didn't get into detail about the exact changes it had made on this front.

This week the nonprofit Linux Foundation announced the launch of the High Performance Software Foundation, which "aims to build, promote, and advance a portable core software stack for high performance computing" (or HPC) by "increasing adoption, lowering barriers to contribution, and supporting development efforts."

It promises initiatives focused on "continuously built, turnkey software stacks," as well as other initiatives including architecture support and performance regression testing. Its first open source technical projects are:

- Spack: the HPC package manager.

- Kokkos: a performance-portable programming model for writing modern C++ applications in a hardware-agnostic way.

- Viskores (formerly VTK-m): a toolkit of scientific visualization algorithms for accelerator architectures.

- HPCToolkit: performance measurement and analysis tools for computers ranging from desktop systems to GPU-accelerated supercomputers.

- Apptainer: Formerly known as Singularity, Apptainer is a Linux Foundation project providing a high performance, full featured HPC and computing optimized container subsystem.

- E4S: a curated, hardened distribution of scientific software packages.

As use of HPC becomes ubiquitous in scientific computing and digital engineering, and AI use cases multiply, more and more data centers deploy GPUs and other compute accelerators. The High Performance Software Foundation will provide a neutral space for pivotal projects in the high performance computing ecosystem, enabling industry, academia, and government entities to collaborate on the scientific software.

The High Performance Software Foundation benefits from strong support across the HPC landscape, including Premier Members Amazon Web Services (AWS), Hewlett Packard Enterprise, Lawrence Livermore National Laboratory, and Sandia National Laboratories; General Members AMD, Argonne National Laboratory, Intel, Kitware, Los Alamos National Laboratory, NVIDIA, and Oak Ridge National Laboratory; and Associate Members University of Maryland, University of Oregon, and Centre for Development of Advanced Computing.
In a statement, an AMD vice president said that by joining "we are using our collective hardware and software expertise to help develop a portable, open-source software stack for high-performance computing across industry, academia, and government." And an AWS executive said the high-performance computing community "has a long history of innovation being driven by open source projects. AWS is thrilled to join the High Performance Software Foundation to build on this work. In particular, AWS has been deeply involved in contributing upstream to Spack, and we're looking forward to working with the HPSF to sustain and accelerate the growth of key HPC projects so everyone can benefit."

The new foundation will "set up a technical advisory committee to manage working groups tackling a variety of HPC topics," according to the announcement, following a governance model based on the Cloud Native Computing Foundation.

Intel unveiled Thunderbolt Share on Wednesday with which it promises to streamline screen and file sharing between two PCs. Tom's Hardware: Thunderbolt Share will allow PC owners to connect their two computers with a wired connection that leverages Thunderbolt's speed (40Gbps or higher), low latency, and built-in security. It allows PC-to-PC access that shares the screen, keyboard, mouse, and storage. The software also enables folder synchronization or easy drag-and-drop file transfer between the computers. [...]

Thunderbolt Share also provides uncompressed screen sharing between two PCs in the original resolution of the source computer. It also claims low latency for a smooth, responsive experience that includes the screen, keyboard, and mouse with full HD screen mirroring at up to 60 frames per second (fps). Higher resolutions could result in fewer frames per second, but Ziller said it would still be a "great experience."
