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
The Intel Xeon plus NVIDIA A100 cluster of Kakao Enterprise's kakaocloud, one of two kakaocloud systems that entered the TOP500 in June 2024. TOP500 lists an eSlim Korea SP7-2608WG cluster with Xeon Platinum 8358 32C 2.6GHz hosts, NVIDIA A100 80GB GPUs and InfiniBand HDR200 under Ubuntu 22.04.3 LTS, installed 2024, with 115,072 cores, Rmax 15.94 PFlop/s and Rpeak 17.82 PFlop/s; it ranked 70th in June 2024 (its best position) and 136th in June 2026. Byline Network's report on that list gives the same rank, core count, 15.94 PFlop/s and 89.5 percent efficiency, so the tier is verified. The larger sister system (AMD EPYC 7763 hosts with A100, 32.00 PFlop/s, rank 41 in November 2024) is not recorded as a separate row here. No power figure or data-centre location is published.
