一 | TOKYO -- The operator of the Fukushima Daiichi nuclear power plant said the discharge of the second batch of treated radioactive wastewater into the sea ended as planned on Monday, and International Atomic Energy Agency officials in Japan for their first safety and monitoring mission since the release began two months ago said “no issues” were observed.Fukushima Daiichi started releasing treated and diluted radioactive wastewater into the sea on Aug. 24. The operator, Tokyo Electric Power Company Holdings, said the release of a second, 7,800-ton batch of treated wastewater was completed, with its daily seawater sampling results fully meeting safety standards.A magnitude 9.0 quake on March 11, 2011, triggered a massive tsunami that destroyed the plant’s power supply and cooling systems, causing three reactors to melt and spew large amounts of radiation. Highly contaminated cooling water applied to the damaged reactors has leaked continuously into building basements and mixed with groundwater.The release of treated wastewater is expected to continue for decades. It has been strongly opposed by fishing groups and neighboring countries including South Korea, where hundreds of people have protested. China banned all imports of Japanese seafood the day the release began, badly hurting Japanese seafood producers, processors and exporters. Russia recently joined China in the trade restrictions.“I would say that the first two batches of releases went well. No issues were observed," Lydie Evrard, IAEA deputy director general and head of the department of nuclear safety and security, told a Tokyo news conference. She said she visited Fukushima Daiichi on Friday for a firsthand look.Evrard's visit came on the heels of a marine sampling mission by another IAEA team that included scientists from China, South Korea and Canada. She said all participants in that mission said their activity went well. She did not say whether Chinese scientists acknowledged the safety of the release.She said China has been involved in the IAEA safety task force since the beginning of the review that began two years ago and has participated in corroboration activities. The IAEA is aware of China’s concern and engaged with its authorities, Evrard said.Japanese Prime Minister Fumio Kishida, in his policy speech Monday, renewed his call for China to immediately lift its ban on Japanese seafood imports.During the Oct. 16-23 visit, the IAEA sampling team collected seawater, sediment and fish from near the plant and visited a marine laboratory near Tokyo that makes fish specimens for radiation analysis by institutions in and outside Japan, including the IAEA.During Evrard's visit, IAEA task force and Japanese officials are expected to discuss the safety of the ongoing discharge and their future mission plans, with a report expected by the end of the year. She said the discharge plan would be updated with new findings and data collected over the past two months.The IAEA, based on its two-year review of TEPCO's wastewater release plan, concluded in July that if it is carried out as planned, it will have a negligible impact on the environment, marine life and human health.Japan’s government and TEPCO say the discharge is unavoidable because wastewater storage tanks at the plant will be full next year. They say the water produced by the damaged plant is treated to reduce radioactivity to safe levels, and then diluted with massive amounts of seawater to make it much safer than international standards.TEPCO has said it plans to release 31,200 tons of treated water by the end of March 2024, which would empty only 10 tanks out of 1,000 because of the continued production of wastewater at the plant.。 8月25日消息，在Hot Chips 2026大会上，英特尔展示了面向智能体AI及企业级工作负载的三款架构，包括适用于以更高性能去调度与协同的Diamond Rapids处理器、支持高效推理的Crescent Island GPU，以及用于智能客户端与边缘计算的Wildcat Lake SoC。 其中代号Crescent Island（新月岛）的全新GPU加速器，是一款专为AI推理与智能体工作负载打造的低功耗、易部署GPU，不再兼顾传统的图形渲染性能。 Crescent Island采用标准PCIe 5.0 x16规格，整卡TDP功耗350W，配套成熟风冷散热方案，企业可以直接在现有风冷服务器上架部署，无需改造昂贵的液冷基础设施，通过合作伙伴的定制方案，其容量最高可扩展至480GB。
二 | 架构层面，Crescent Island首发搭载第三代Xe架构增强版本Xe3P，Xe3P是Panther Lake处理器内置Xe3架构的迭代增强版本，按照英特尔路线规划，这套架构未来将落地PC客户端、数据中心、边缘计算、工作站多条产品线，具备很高的通用性与拓展潜力。 为拔高AI推理能效，英特尔还对Xe3P核心做了大规模改造，AI矩阵计算XMX单元，从Xe2、初代Xe3的4层深度脉动阵列升级到16层，原生新增支持FP4、FP8低精度AI计算，同时完整覆盖FP16、FP32直至FP64全精度。 单Xe核心寄存器堆容量直接翻倍至1MB，L1缓存与SLM共享局部缓存提升到512KB，减少数据读写延迟，提升大模型吞吐能力。 芯片设计上，Crescent Island贯彻去图形化思路，完全移除3D渲染、光线追踪全套硬件模块，把节约下来的全部晶体管资源投入Xe计算核心与AI加速单元。 整卡内部划分4组Compute Slice计算块，集成32个Xe3P核心，合计拥有256个矢量引擎、256个XMX矩阵AI引擎，全部算力资源服务AI推理任务。
三 | 软件生态上，该加速器原生适配vLLM、SGLang、PyTorch等当下主流AI推理框架，降低企业落地大模型的适配成本。
