Nano 4
Operated by National Center for High-Performance Computing at NCHC Hsinchu .
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
ASUS's own press release and TOP500's listing agree exactly on rank, power and efficiency figures. Built for Taiwan's national research, government and industry users; ASUS names generative AI, big data, deep learning and traditional HPC as its intended workloads, which is why this row is tagged mixed. A co-located, separate NVIDIA GB200 NVL72 system at the same facility is not part of this entry.

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.
