FFmpeg Devs Boast of Up To 94x Performance Boost After Implementing Handwritten AVX-512 Assembly Code

Anton Shilov reports via Tom's Hardware: FFmpeg is an open-source video decoding project developed by volunteers who contribute to its codebase, fix bugs, and add new features. The project is led by a small group of core developers and maintainers who oversee its direction and ensure that contributions meet certain standards. They coordinate the project's development and release cycles, merging contributions from other developers. This group of developers tried to implement a handwritten AVX512 assembly code path, something that has rarely been done before, at least not in the video industry. The developers have created an optimized code path using the AVX-512 instruction set to accelerate specific functions within the FFmpeg multimedia processing library. By leveraging AVX-512, they were able to achieve significant performance improvements -- from three to 94 times faster -- compared to standard implementations. AVX-512 enables processing large chunks of data in parallel using 512-bit registers, which can handle up to 16 single-precision FLOPS or 8 double-precision FLOPS in one operation. This optimization is ideal for compute-heavy tasks in general, but in the case of video and image processing in particular. The benchmarking results show that the new handwritten AVX-512 code path performs considerably faster than other implementations, including baseline C code and lower SIMD instruction sets like AVX2 and SSSE3. In some cases, the revamped AVX-512 codepath achieves a speedup of nearly 94 times over the baseline, highlighting the efficiency of hand-optimized assembly code for AVX-512.

visionOS 2.2 Beta Adds Wide and Ultrawide Modes To Mac Virtual Display

Apple released the first beta of visionOS 2.2, introducing new "Wide" and "Ultrawide" modes for the Mac Virtual Display feature on the Vision Pro headset. MacRumors reports: Apple has previously said the ultra-wide version of Mac Virtual Display is equivalent to having two physical 4K displays sitting side by side on a desk. Mac Virtual Display is now available in three sizes: Normal, Wide, and Ultrawide. visionOS 2.2 will likely be released to the public in December alongside iOS 18.2, iPadOS 18.2, macOS Sequoia 15.2, watchOS 11.2, tvOS 18.2, and other updates.

Sweden Scraps Plans For 13 Offshore Windfarms Over Russia Security Fears

An anonymous reader quotes a report from The Guardian: Sweden has vetoed plans for 13 offshore windfarms in the Baltic Sea, citing unacceptable security risks. The country's defence minister, Pal Jonson, said on Monday that the government had rejected plans for all but one of 14 windfarms planned along the east coast. The decision comes after the Swedish armed forces concluded last week that the projects would make it more difficult to defend Nato's newest member. The proposed windfarms would have been located between Aland, the autonomous Finnish region between Sweden and Finland, and the Sound, the strait between southern Sweden and Denmark. The Russian exclave of Kaliningrad is only about 310 miles (500km) from Stockholm. Wind power could affect Sweden's defence capabilities across sensors and radars and make it harder to detect submarines and possible attacks from the air if war broke out, Jonson said. The only project to receive the green light to was Poseidon, which will include as many as 81 wind turbines to produce 5.5 terawatt hours a year off Stenungsund on Sweden's west coast. "Both ballistic robots and also cruise robots are a big problem if you have offshore wind power," Jonson said. "If you have a strong signal detection capability and a radar system that is important, we use the Patriot system for example, there would be negative consequences if there were offshore wind power in the way of the sensors."

New Mac Mini Has Modular Storage, 256GB Model Will Have Faster SSD

According to a partial teardown video of Apple's new Mac mini, the new machine features modular storage that can be removed. "As we saw with the Mac Studio, however, replacing the modular storage is complicated," notes MacRumors. The teardown also reveals two 128GB storage chips in the 256GB model, enabling faster SSD speeds comparable to higher-capacity versions. From the report: The criticism surrounding Apple's decision to use a single 256GB chip in some base-model Macs a few years ago primarily came from a vocal contingent of tech enthusiasts, and the average customer is unlikely to even notice the slower speeds in common day-to-day tasks. Nevertheless, it appears that customers who do want the fastest SSD speeds do not need to worry about which storage capacity they choose when ordering the new Mac mini.

How close are we to an accurate AI fake news detector?


In the ambitious pursuit to tackle the harms from false content on social media and news websites, data scientists are getting creative. While still in their training wheels, the large language models (LLMs) used to create chatbots like ChatGPT are being recruited to spot fake news. With better detection, AI fake news checking systems may be able to warn of, and ultimately counteract, serious harms from deepfakes, propaganda, conspiracy theories and misinformation. The next level AI tools will personalise detection of false content as well as protecting us against it. For this ultimate leap into user-centered AI, data science needs…
