Also known as Taiwan CWA Fujitsu PRIMEHPC FX1000

Operated by Central Weather Administration at CWA Computing Centre (Taipei) .

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.

Measured performance

Rmax: 11.16 PFlop/s
Rpeak: 12.98 PFlop/s
Rmax ÷ Rpeak: 86.0%
Cores: 184,320
Power: 673.56 kW
Per watt: 16.6 GF/W

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

Taiwan's Central Weather Administration numerical weather prediction system, built from Fujitsu PRIMEHPC FX1000 nodes with the same A64FX 48C 2.2 GHz CPU as Fugaku on Tofu interconnect D. TOP500 lists the larger of its two FX1000 entries at 184,320 cores, 11.16 PFlop/s Rmax, 12.98 PFlop/s Rpeak and 674 kW, ranked 68 in November 2023 and 173 in June 2026; a second entry at the same site has 92,160 cores and 5.60 PFlop/s Rmax (TOP500 system 180215) and is not recorded separately. Tech Wire Asia, citing Fujitsu, reports a roughly 10 PFlop/s theoretical peak system with operation starting in June 2022 and completion in December 2023, a figure lower than the combined TOP500 Rpeak, so the TOP500 numbers are used for this row.

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.
