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
A Saudi Aramco Dell cluster of Intel Xeon Gold 6130 16-core nodes on Intel Omni-Path, with 53,300 cores, Rmax 2.32 and Rpeak 3.58 PFlop/s at 608 kW, installed in 2018 and running RHEL 7.4. It debuted at 78th on the June 2018 TOP500 and had slipped to 495th by November 2024, the latest list on which we found it. The TOP500 system name also mentions Xeon Phi 7250 parts; TOP500 is the only source, so the tier is reported and the site is left unlocated. Aramco's later Dammam-7, Ghawar-1 and Tuwaiq-1 are separate entries.

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.
