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.
| Role | Part | Supplier at build | Quantity | Confidence | Source |

The read
RIKEN Super Combined Cluster, a Fujitsu Linux cluster ordered in July 2003 as a model for next-generation large computing centres. Fujitsu's order announcement gives 2,048 CPUs, 12.4 TFlop/s, an InfiniBand interconnect, grid computing technology, use mainly for bioinformatics, and operation scheduled for March 2004; it was to serve RIKEN's Wako, Yokohama, Kobe and Harima sites and link into the ITBL grid. TOP500 lists 2,048 Pentium 4 Xeon 3.06 GHz cores on Myrinet and InfiniBand, 8.728 TFlop/s Rmax and 12.534 TFlop/s Rpeak, 7th on the June 2004 list and last seen in November 2007. Fujitsu's 2009 RICC release calls RSCC the previous system. The Fujitsu page is a pre-delivery order notice and the peak figures differ slightly (12.4 versus 12.534), 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.
| Cited source | Result | Found on the page |
