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.

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
SGI Altix ICE 8200 cluster of Intel Xeon X5365 3.0 GHz quad-core processors on InfiniBand, funded by the State of New Mexico and operated by the non-profit New Mexico Computing Applications Center in an Intel data centre in Rio Rancho. TOP500 lists 14,336 cores, 172.03 TFlop/s peak and 861 kW and places it third in the world on the November 2007 list at 126.9 TFlop/s Rmax; its system page also shows a later 133.2 TFlop/s figure. Data Center Knowledge describes about 14,000 cores and 172 trillion calculations per second, water cooling, and the state's later repossession of the machine over unpaid debt. TOP500 is the only source for Rmax, so the tier is reported.

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.
