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
NCHC's GPU supercomputer, the predecessor of Taiwania 3 in this dataset: 252 QCT QuantaGrid D52G-4U/LC nodes with two Intel Xeon Gold CPUs (9,072 CPU cores) and eight NVIDIA Tesla V100 32GB GPUs each (2,016 in all), 768 GB of RAM per node, EDR InfiniBand, 10 PB of storage and warm-water liquid cooling at a PUE of 1.2. It debuted 20th on the November 2018 TOP500 with 9.0 PFlop/s Rmax, and 10th on the Green500. NCHC's page quotes 9 PFlop/s peak and TOP500 gives 15.21 PFlop/s Rpeak, so no peak is recorded and the conflict is logged. TOP500's 170,352 core count includes GPU cores. NCHC's current supercomputer page still describes it as operational, though the page is undated and no go-live date was found. The V100 edge is verified by NCHC and QCT, and Rmax comes from TOP500 and QCT, so the system tier 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.
