NIPA(NHN Cloud)-CL-2
Operated by NHN Cloud at NHN Cloud FactoryX Seoul .
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
The smaller of NHN Cloud's two NIPA-funded clusters, on the same Seoul site and identical hardware stack as CL-1, one floor apart in the same facility.

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 |
|---|---|---|
| top500.org | names system and part | NVIDIA B200 SXM, AMD EPYC 9005 (Turin), NVIDIA InfiniBand NDR (Quantum-2) |
| digitaltoday.co.kr | does not name this system | NVIDIA B200 SXM |
