Operated by KT Corporation .
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
Korea Telecom's NVIDIA DGX A100 SuperPOD as listed on the TOP500: AMD EPYC 7742 64C 2.25GHz hosts, NVIDIA A100 GPUs, Infiniband HDR, Ubuntu 20.04.2 LTS, 98,208 cores, Rmax 10.38 PFlop/s and Rpeak 14.42 PFlop/s, installed 2022. Its TOP500 rank has drifted from 58 in June 2023 to 179 in June 2026. KT has not stated a workload in any source fetched, so the AI-training class is inferred from the DGX SuperPOD architecture. The data-center site is not published, so it is left unlocated. Single-source (TOP500), so confidence 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 |
