China has reclaimed the title of the world’s fastest supercomputer after its newly developed system – LineShine – topped the latest TOP500 global ranking of supercomputers.
The ranking, unveiled on June 22 at the International Supercomputing Conference in Hamburg, Germany, marks the first time since 2017 that a Chinese-built machine has led the global list.
LineShine displaced the United States’ El Capitan supercomputer, which previously held the top position and now ranks second.
Located in Shenzhen, southern China, LineShine achieved a sustained performance of 2.2 exaflops, a measure used to determine how many calculations a computer can perform per second.
A key highlight of the achievement is that the system was built entirely with processors designed and produced in China, reflecting the country’s growing push for self-reliance in advanced technology and high-performance computing.
The TOP500 ranking, published twice yearly since 1993, is regarded as a global benchmark for measuring supercomputing performance and technological competitiveness among nations.
Despite losing the top spot, the United States continues to dominate the rankings, occupying three of the top four positions, including El Capitan, which is housed at the Lawrence Livermore National Laboratory in California.
The development is seen as a significant milestone in China’s efforts to strengthen its position in advanced computing and reduce dependence on foreign technology.
