Operated by Geely .
Phase 1 seed dataset, compiled by hand. These rows were built from public operator, laboratory and vendor sources. A mechanical second-reader pass has since fetched every cited source: 1263 of 1345 systems have a readable citation that names them, and 56 are genuinely weakly sourced. Every claim carries its source and a confidence tier. Treat anything below verified as a lead, not a citation.

What this machine is made of
One row per supplier relationship. “Supplier at build” is the company that shipped the part at the time; where that company has since been acquired, the parent it rolls up to today is shown beside it. That distinction is what makes ticker-level aggregation possible across a thirty-year dataset.

The read
Geely Auto Group's Lenovo ThinkSystem SD650 V3 cluster of Xeon Gold 6458Q 32C 3.1GHz processors on InfiniBand HDR, running Linux: 40,960 cores at 3.54 PFlop/s Rmax and 4.06 PFlop/s Rpeak, installed 2023. It debuted at rank 185 on the June 2023 list and is still listed at rank 383 on June 2026, which is the basis for the status date. Whether it forms part of the Xingrui Intelligent Computing Center already in this dataset is not stated in the sources fetched, so it is kept as its own row.

Source check
We fetched this system's own citations and recorded whether each page actually mentions it. This is a corroboration signal, not a fact check, and it is published so you can see how well the sourcing holds up rather than take it on trust.
