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
One of the largest Lenovo-integrated systems anywhere, and a reminder that Lenovo's position in this market came from a single 2014 transaction: IBM's x86 server business. Warm-water cooled with heat recovery, on Intel Omni-Path - a fabric its own vendor discontinued the year after this machine entered service. TOP500 independently lists Lenovo, Xeon Platinum 8174, 305,856 cores, Rmax 19.48 and Rpeak 26.87, all matching the LRZ page, so the tier is verified. The Gauss Centre quotes a 26.7 PFlop/s peak, the figure planned before installation, which differs from the measured 26.87.

Where sources disagree
We record conflicts instead of picking a winner quietly. All open questions.
- Rpeak: 26.7 PFlop/s (planned, Gauss Centre) against 26.87 PFlop/s (TOP500). The lower figure is the pre-installation plan; TOP500's measured peak is used.

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.
