China claims the world’s fastest supercomputer

中国宣称拥有全球最快超级计算机

LineShine has pushed the US out of the number-one spot on the TOP500 ranking. LineShine 已将美国挤下 TOP500 排行榜的榜首位置。

Despite trade restrictions, China has reclaimed the title of the world’s fastest supercomputer for the first time since 2018. LineShine has pushed El Capitan out of number one on the TOP500 ranking. That’s despite strict limits on what high-powered computing components can be sold to China by US firms, which dominate the list, with America holding three of the top five spots. LineShine doesn’t even use any GPUs, which are typically the backbone of modern supercomputers. 尽管面临贸易限制，中国自 2018 年以来首次夺回了全球最快超级计算机的头衔。LineShine 已将“El Capitan”挤下 TOP500 排行榜的第一名。尽管美国企业在榜单中占据主导地位（前五名中占据三席），且美国对可向中国出口的高性能计算组件实施了严格限制，但中国依然实现了这一突破。值得注意的是，LineShine 甚至没有使用任何通常作为现代超级计算机核心的 GPU。

While reaching the peak of the Top500 carries obvious bragging rights, it also serves as a message from the Chinese government to the US. The Trump administration has sought to limit China’s access to chips from firms like NVIDIA and placed steep tariffs on products going in and out of the country. China responded by building around more readily available and generalized CPUs. LineShine uses roughly 45,000 LX2 processors, each with 304 cores running at 1.55GHz, connected over a special high-speed, low-latency network called LingQi. 虽然登顶 Top500 显然具有象征意义，但这同时也向美国传递了来自中国政府的信息。特朗普政府曾试图限制中国获取英伟达（NVIDIA）等公司的芯片，并对进出口产品征收高额关税。对此，中国的应对策略是围绕更易获取的通用 CPU 进行构建。LineShine 使用了约 45,000 个 LX2 处理器，每个处理器拥有 304 个核心，运行频率为 1.55GHz，并通过一种名为“灵气”（LingQi）的专用高速、低延迟网络进行连接。

LineShine is the first supercomputer to cross the 2,000 exaflop barrier and is 20 percent faster than the number-two system, El Capitan, on the Top500 list. However, it also uses 42.2 megawatts, dramatically higher and less efficient than El Capitan’s 29.7 megawatts. LineShine 是首台突破 2,000 exaflop（百亿亿次浮点运算）大关的超级计算机，其速度比 Top500 榜单上的第二名 El Capitan 快 20%。然而，它的功耗也达到了 42.2 兆瓦，远高于 El Capitan 的 29.7 兆瓦，能效表现相对较低。
