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: 1092 of 1153 systems have a readable citation that names them, and 40 are genuinely weakly sourced. Every claim carries its source and a confidence tier. Treat anything below verified as a lead, not a citation.

Figures are as last publicly reported for the configuration described below, not a live measurement. Where a system was upgraded in place, the post-upgrade configuration is shown and the earlier one appears in the timeline.
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
Skoda Auto's HPE Cray EX cluster of AMD EPYC 9654 (96-core, 2.4 GHz) CPUs on Slingshot-11 running HPE Cray OS, 196,608 cores at 8.40 PFlop/s Rmax and 8.87 PFlop/s Rpeak, CPU-only. It debuted at rank 112 on the June 2024 list and stood at rank 215 on June 2026. TOP500 places the site at Mlada Boleslav, Czechia. Only the TOP500 page is cited for this machine; a September 2025 trade-press article describes a liquid-cooled HPE Cray EX4000 with 4th-generation EPYC for Skoda CFD work, but it does not say it is this same system so it is not cited.

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.
