Slashdot: China's Secretive Sunway Pro CPU Quadruples Performance Over Its Predecessor

China's Secretive Sunway Pro CPU Quadruples Performance Over Its Predecessor
Published on November 25, 2023 at 06:06AM
An anonymous reader shares a report: Earlier this year, the National Supercomputing Center in Wuxi (an entity blacklisted in the U.S.) launched its new supercomputer based on the enhanced China-designed Sunway SW26010 Pro processors with 384 cores. Sunway's SW26010 Pro CPU not only packs more cores than its non-Pro SW26010 predecessor, but it more than quadrupled FP64 compute throughput due to microarchitectural and system architecture improvements, according to Chips and Cheese. However, while the manycore CPU is good on paper, it has several performance bottlenecks. The first details of the manycore Sunway SW26010 Pro CPU and supercomputers that use it emerged back in 2021. Now, the company has showcased actual processors and disclosed more details about their architecture and design, which represent a significant leap in performance, recently at SC23. The new CPU is expected to enable China to build high-performance supercomputers based entirely on domestically developed processors. Each Sunway SW26010 Pro has a maximum FP64 throughput of 13.8 TFLOPS, which is massive. For comparison, AMD's 96-core EPYC 9654 has a peak FP64 performance of around 5.4 TFLOPS. The SW26010 Pro is an evolution of the original SW26010, so it maintains the foundational architecture of its predecessor but introduces several key enhancements. The new SW26010 Pro processor is based on an all-new proprietary 64-bit RISC architecture and packs six core groups (CG) and a protocol processing unit (PPU). Each CG integrates 64 2-wide compute processing elements (CPEs) featuring a 512-bit vector engine as well as 256 KB of fast local store (scratchpad cache) for data and 16 KB for instructions; one management processing element (MPE), which is a superscalar out-of-order core with a vector engine, 32 KB/32 KB L1 instruction/data cache, 256 KB L2 cache; and a 128-bit DDR4-3200 memory interface.

Slashdot: US Army Soldier Pleads Guilty To AT&T and Verizon Hacks

US Army Soldier Pleads Guilty To AT&T and Verizon Hacks Published on February 20, 2025 at 01:31AM Cameron John Wagenius pleaded guilty to hacking AT&T and Verizon and stealing a massive trove of phone records from the companies, according to court records filed on Wednesday. From a report: Wagenius, who was a U.S. Army soldier, pleaded guilty to two counts of "unlawful transfer of confidential phone records information" on an online forum and via an online communications platform. According to a document filed by Wagenius' lawyer, he faces a maximum fine of $250,000 and prison time of up to 10 years for each of the two counts. Wagenius was arrested and indicted last year. In January, U.S. prosecutors confirmed that the charges brought against Wagenius were linked to the indictment of Connor Moucka and John Binns, two alleged hackers whom the U.S. government accused of several data breaches against cloud computing services company Snowflake, which were among the ...

Slashdot: AT&T Now Lets Customers Lock Down Account To Prevent SIM Swapping Attacks

AT&T Now Lets Customers Lock Down Account To Prevent SIM Swapping Attacks Published on July 02, 2025 at 01:30AM AT&T has launched a new Account Lock feature designed to protect customers from SIM swapping attacks. The security tool, available through the myAT&T app, prevents unauthorized changes to customer accounts including phone number transfers, SIM card changes, billing information updates, device upgrades, and modifications to authorized users. SIM swapping attacks occur when criminals obtain a victim's phone number through social engineering techniques, then intercept messages and calls to access two-factor authentication codes for sensitive accounts. The attacks have become increasingly common in recent years. AT&T began gradually rolling out Account Lock earlier this year, joining T-Mobile, Verizon, and Google Fi, which already offer similar fraud prevention features. Read more of this story at Slashdot.

Slashdot: Protecting 'Funko' Brand, AI-Powered 'BrandShield' Knocks Itch.io Offline After Questionable Registrar Communications

Protecting 'Funko' Brand, AI-Powered 'BrandShield' Knocks Itch.io Offline After Questionable Registrar Communications Published on December 16, 2024 at 01:04AM Launched in 2013, itch.io lets users host and sell indie video games online — now offering more than 200,000 — as well as other digital content like music and comics. But then someone uploaded a page based on a major videogame title, according to Game Rant. And somehow this provoked a series of overreactions and missteps that eventually knocked all of itch.io offline for several hours... The page was about the first release from game developer 10:10 — their game Funko Fusion, which features characters in the style of Funko's long-running pop-culture bobbleheads. As a major brand, Funko monitors the web with a "brand protection" partner (named BrandShield). Interestingly, BrandShield's SaaS product "leverages AI-driven online brand protection," according to their site, to "detect...
