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
An HP Cluster Platform 3000 BL460c blade cluster listed with Jeraisy Computer and Communication Services of Saudi Arabia as the site, installed in 2009. TOP500 lists 4,192 cores of Xeon E5450 4C 3GHz on 4x DDR InfiniBand running Linux, 39.70 TFlop/s Rmax and 50.30 TFlop/s Rpeak, ranked 99th on the June 2009 list and 122nd on the November 2009 list, which is the basis for the status date. TOP500 also lists a Saudi Aramco entry (system 176236) with identical core count, interconnect and performance figures, which suggests one machine listed under both names; no page we fetched explains the relationship, so this row records only the Jeraisy listing. TOP500 is the only source, no power figure is listed and the site is not stated, so the system is unlocated and 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.
| Cited source | Result | Found on the page |
