Equipped with China's homegrown BeiDou positioning systems, drones and sensors, four vessels began trial runs along China's Pinglu Canal on Wednesday. The canal, which is planned for opening in September, will greatly inject economic vitality to areas along its route and turbocharge China's trade connection with the ASEAN with its cost-saving transportation, a Chinese analyst said.
The vessels conducting trials on Wednesday represent the main types expected to sail on this canal, namely loaded and unloaded 5,000-tonne ships as well as loaded 3,000-tonne and 1,000-tonne vessels, Xinhua News Agency reported.
The trials began when an unloaded 5,000-ton vessel departed from the Xinfu service area along the canal in South China's Guangxi Zhuang Autonomous Region, the Xinhua News Agency reported.
With sensors collect data on their routes, movements, water currents and safe distances between ships, the tests will assess navigation under both normal and adverse conditions and examine whether the canal's waterways, locks, anchorages, service areas and navigation facilities are ready for operation.
Chinese analysts said the tests starting on Wednesday, days after the canal completed its first full-route patrol, indicated that the canal is one step closer to its scheduled opening in September as final preparation work ramp up.
Zheng Ping, chief analyst at industry news portal chineseport.cn, told the Global Times on Wednesday that as a major project in the nation's water network, the opening of the canal later this year will bring sea changes to areas along its route with fresh economic opportunities with its role as a low-cost enabler for domestic and international trade.
"Inland water traffic has great advantage in transportation capacity and costs. While a train can typically carry 20 40-foot container or more, a waterborne vessel can easily carry over 100 such containers. So a five-times capacity is gained here, greatly reducing transportation costs for goods," Zheng said.
For goods that are not time sensitive, or for bulk cargo such as coal, aluminum or fertilizers, waterborne traffic has unparallel advantage, the expert noted.
The 134.2-kilometer-long Pinglu Canal is a key project of the New International Land-Sea Trade Corridor. With total investment exceeding 70 billion yuan ($10.37 billion), the canal begins at the Pingtang River estuary in Hengzhou, administered by Nanning, follows the Qinjiang River into the Beibu Gulf, according to Xinhua News Agency.
It is China's first major river-to-sea canal project planned and coordinated at the national level since 1949 and is designed to accommodate vessels of up to 5,000 tons.
In addition to facilitating transportation, modern canal system will also have the function of water resource diversion, flood control and irrigation, greatly boosting up local economic development, Zheng said.
Lei Xiaohua, deputy director of the Institute of Southeast Asian Studies at the Guangxi Academy of Social Sciences in South China's Guangxi Zhuang Autonomous Region, told the Global Times on Wednesday that the Pinglu Canal will serve as a new engine for the deep integration of industrial chains between China and ASEAN.
"Raw materials from ASEAN can enter China's hinterland via the Beibu Gulf ports at lower costs, while Chinese exports including aluminum products and building materials can reach Southeast Asia more efficiently," Lei said.
Against the backdrop of deep industrial chain integration between China and Vietnam, the canal, which offers a low-cost, high-capacity transport route, is poised to foster new models of cross-border industrial capacity cooperation, said Lei.
When operational in September, the canal will give inland regions in Southwest China a more direct river route to the sea. Cargo that previously had to travel eastward through the Port of Guangzhou will be able to head south directly toward ports in the Beibu Gulf, shortening some inland waterway journeys by about 560 kilometers, according to Xinhua.
The New International Land-Sea Trade Corridor is an international trade and logistics network connecting China's western regions to ASEAN countries and other overseas markets.
The corridor has continued to record strong trade growth. During the first half of 2026, imports and exports transported through the corridor by its participating regions reached 517.23 billion yuan, up 13 percent year-on-year and setting a new record for the same period, per data released by Chongqing municipal government.
The corridor's rail service handled a record 1.425 million 20-foot equivalent units of cargo in 2025, up 47.6 percent year-on-year. As of early June of 2026, its network reached 593 ports in 128 countries and regions.
。 IT之家 7 月 22 日消息，英伟达昨日（7 月 21 日）发布博文，从技术角度详细介绍了 Vera CPU，专为智能体 AI（Agentic AI）场景设计。 英伟达表示智能体 AI 将更多的关键执行路径转移到了 CPU 上。智能体（Agents）在沙箱中运行代码、调用工具、检索上下文、与数据库交互以及分析结果，然后再将信息返回给模型。 IT之家援引博文介绍，智能体 AI 工作负载主要取决于以下几点： 即使插槽完全负载，也需要强大的单线程性能。 每个核心都有足够的内存带宽，以持续为许多活跃的执行上下文提供数据。
B | 并发下的延迟具有可预测性，以便智能体能够稳定完成预定步骤。 高效处理不规则控制流、长依赖链和指针密集型数据结构。 英伟达在博文中强调，Vera CPU 围绕智能体 AI 负载设计，重点提升满负载条件下的单线程表现，其设计核心是 Olympus 核心。
C | 英伟达强调 Olympus 核心采用前端、核心中段、执行引擎和缓存子系统四部分设计。
D | 前端集成 10 宽解码引擎，并支持每周期最多处理 2 个已采用分支。其分支预测子系统包含神经分支预测器，用于提升复杂分支模式下的预测准确性。 该公司表示，Vera CPU 共配备 88 个 Olympus 核心和 176 个 SMT 线程，目标是在单线程高负载与更高线程密度两类场景间切换，并降低线程间资源争用。 在片上互连与缓存部分，Vera CPU 搭载 NVIDIA 可扩展相干互连，即 NVIDIA Scalable Coherency Fabric（SCF）。 NVIDIA 称，这一互连提供最高 3.4 TB/s 双向分区带宽，并在全核心范围内集成 164 MB 统一 L3 缓存，连接核心、共享缓存、内存控制器、I/O 与 NVLink-C2C 接口。 内存方面，Vera CPU 采用 SOCAMM2 LPDDR5X 内存。NVIDIA 称，该子系统聚合带宽最高 1.2 TB/s，按单核计算最高 14 GB/s，面向高并发 AI、分析、图计算与强化学习负载供数。 扩展与 I/O 方面，NVIDIA 称 Vera CPU 支持双路扩展，通过第二代 NVLink-C2C 构建一致性双路平台。 双路配置下，平台提供 176 条 PCIe 6.4 通道，并支持 CXL 3.1。保密计算方面，Vera CPU 基于 Arm CCA / RME，支持按虚拟机分配加密密钥，并使用经认证的 C2C 加密保护一致性链路数据。
