# LineShine **Entity class:** Exascale supercomputer **Domain:** High-performance computing / China / technological sovereignty **Doc Type:** Developed System Node **Maturity:** Operational **As of:** 2026-09-20 ## Definition **LineShine** is a Chinese supercomputer installed at the National Supercomputing Centre in Shenzhen. It debuted at number one on the June 2026 TOP500 list with 2.198 exaflops on the HPL benchmark and 13,789,440 cores. ## Denial-War Context LineShine uses indigenous processors, interconnect, and system software. Its appearance follows years of U.S. controls on Chinese supercomputing organizations and access to advanced processors, making it a central case for evaluating whether denial retards capability, accelerates substitution, or produces both effects at different times. ## Evidence Ledger - **Established:** TOP500 ranked LineShine first in June 2026 at 2.198 exaflops. - **Established:** The system is installed in Shenzhen and uses a domestically developed architecture. - **Strongly indicated:** It represents sovereign substitution under sustained technology restrictions. - **Unresolved:** The causal contribution of individual export controls to its architecture and schedule; design histories, procurement files, and policy documents would settle the relationship. ## Sources / Provenance - [TOP500, June 2026 list](https://www.top500.org/lists/top500/2026/06/). - [Shenzhen Government Online, LineShine announcement](https://www.sz.gov.cn/en_szgov/business/news/content/post_12866434.html). - [[articles/A History of Machine Intelligence|A History of Machine Intelligence]]. ## Relationships - **Case within:** [[wiki/Denial Wars|Denial Wars]] and [[wiki/Technological Sovereignty|Technological Sovereignty]]. - **Responds to the environment shaped by:** [[wiki/Entity List|Entity List]].
