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
Taiwan's first state-owned petascale supercomputer, a Fujitsu PRIMERGY system with Intel Xeon Gold 6148 CPUs on Omni-Path, activated on 9 May 2018 after a two-year NT$430 million programme. The Taipei Times describes 630 CPU nodes plus 64 mixed CPU/GPU nodes with 256 NVIDIA P100 accelerators and a 1.33 PFLOPS peak claim, seven times the power of its predecessor ALPS. TOP500 lists 27,200 cores, 1.33 PFLOPS Rmax, 2.09 PFLOPS peak and 332 kW; it debuted at 96th in November 2017 and was 148th in June 2018. Focus Taiwan reported in July 2024 that the Forerunner 1 system replaced the retired Taiwania 1, with no retirement date given, so the status date is the data refresh.

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.
