Mateo Valero discusses history of vector architectures: Back to the Future in #HPC and #AI. He also mentions the three quantum computers connected to an NVIDIA Blackwell system in BSC's chapel ⛪️. Ending his talk looking for a future site 😀.

Yutong Lu reveals the LineShine exascale architecture for #HPC - #AI convergence: 2 exaflop sustained fp64 at 40 MW with 1.34 million ARM CPUs using SME and 4TB/s HBM connected with 800G. From "offline to online acceleration with SME".

Taisuke Boku follows on another interesting note: Japan is "changing lanes" from CPU to GPU and from "Made in Japan" to a collaborative "Made with Japan", partnering Fujitsu with NVIDIA. "We don't chase fp64 performance but focus on #AI flops". Onward!

Jack Dongarra's opening keynote at HACI 2026! #HPC in transition - the investments in compute infrastructure are unprecedented but focus mostly on #AI workloads. Scientific numerical simulations need to adjust! Many interesting challenges ahead.

Claude Code 泄露了全部源码——不是被黑客攻破，是 Anthropic 自己把 source map 打包进了 npm 发布物。 一个 57MB 的 cli.js.map 文件，里面藏着 4756 个源文件的完整内容。其中 1906 个是 Claude Code 自身的 TypeScript/TSX 源码，剩下 2850 个是 node_modules 依赖。 提取方法极其简单：cli.js.map 本质就是一个 JSON，里面有两个关键数组——sources（文件路径）和 sourcesContent（对应的完整源码）。两者索引一一对应。不需要反编译，不需要反混淆，sourcesContent 里存的就是一字不差的原始代码。提取脚本见文末。 从还原的源码可以看到：Claude Code 用 React Ink 构建 CLI 界面，核心是一个 REPL 循环，支持自然语言输入和 slash 命令，底层通过工具系统与 LLM API 交互。架构设计、系统提示词、工具调用逻辑，全部一览无余。 这件事的本质是一个经典的安全疏忽：source map 是开发调试用的，包含从变量名到注释的所有信息，不应该出现在生产发布物中。Anthropic 后来意识到了这个问题，移除了 source map，GitHub 上提取源码的仓库也被 DMCA 了。但早期版本的 npm 包已经被存档，源码早就在社区流传。 给所有发布 npm 包的开发者提个醒：发布前检查你的 .map 文件。一行 sourcesContent 就能让你的所有代码公之于众。 gist.github.com/sorrycc/ec29…

有点强啊，已经研究了两小时了，补充了很多缺失的知识点。 可以说是我目前看到最全的 OpenClaw 学习教程！ 中推的博主有一个非常好的点，那就是大家做的内容真的非常优质，因为只有真正优质的内容才可以跑出来。 相比于国内一些标题党，如果遇到要学习的内容，问一下 Grok，给你推荐一些内容，是真的有学习的价值！ 推荐收藏！

Nvidia faces criticism from the HPC community over flat FP64 gains as GPUs pivot toward AI. While experts like Jack Dongarra note limited 64-bit progress, Nvidia says FP64 isn’t abandoned, and future GPUs will boost it. Read more: ow.ly/5uy050XJxTX

Surprise but happy to meet @thoefler in Shenzhen during the #CGC25. Next time will be in SCA/HPC Asia chaired by @ProfMatsuoka in Oasaka next January.

Registraion for the SC/HPC Asia 2026 @ Osaka is open. Register now! sca-hpcasia2026.jp/ It will become the biggest HPC/AI/Quantum research&industry event in Asia, at the scale of EU ISC, with over 100 global exhibitors, 36 papers/101 submitted, 28 workshops, 20 tutorials, over 20 BoFs, posters, multiple invited sessions, and more.

I will be hosting the last panel of the “Global Commons Forum” cgc.ifi.u-tokyo.ac.jp/gcf/ along with my friends Hiroaki Kitano @ SONY-OIST and Thomas Schulthess @ ETH-CSCS etc. to be held at U-Tokyo. We will discuss the plus&minuses of modern HPC & AI towards global sustainability.

The Deepseek team seems to continue keeping a low profile in China. I didn't see any booth or talk from them during #WAIC25. AI is hot, while @deepseek_ai keeps cool. Looking forward to their V4 and R2 soon!

Who will take care of the old people? i see the future. #WACI25 in Shanghai.

I saw the HUAWEI CloudMatrix 384 at #WAIC25 in Shanghai.
