Researched with AI assistance, checked by scripts. These rows were researched by AI agents reading public operator, laboratory and vendor sources, appended by scripts and checked by automated validation; no subject-matter expert has reviewed them (how this site is made). A mechanical second-reader pass has since fetched every cited source: 1350 of 1540 systems have a readable citation that names them, and 64 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
Cray Y-MP C916/16512 filed by TOP500 under the KISTI Supercomputing Center: 16 vector processors (238 MHz per TOP500), UNICOS, Rmax 13.7 and Rpeak 15.24 GFlop/s, identical in every appearance. It entered the list at rank 23 in November 1993 and last appeared at rank 487 in June 1998 (https://www.top500.org/system/172820/). The Korea Meteorological Administration's supercomputer history page says the Systems Engineering Research Institute (SERI, under KIST) bought a Cray Y-MP C90 in 1993 as Korea's second supercomputer, retiring the first, a Cray-2S from 1988; Wikipedia's KISTI timeline dates 'Supercomputer No. 2 (CRAY C/90)' to November 1993, which is the first-operational date used here. KISTI itself was only founded in 2001 (KORDIC, set up in 1993, merged with KINITI in 2000), so the machine belongs to the SERI/KORDIC predecessor lineage and TOP500 simply attributes it to the later institute. TOP500 also records a Cray T3E-900 at the same centre from 1997. No retirement date was found, so status is held as of the last list appearance.

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.
