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: 795.90 TFlop/s
Rpeak: 1.07 PFlop/s
Rmax ÷ Rpeak: 74.4%
Cores: 137,200
Power: 1.07 MW
Per watt: 0.7 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

NRCPC's system for the National Supercomputing Center in Jinan, completed in October 2011 and the direct predecessor to Sunway TaihuLight: the same design organisation, five years and one processor generation apart. 8,704 ShenWei SW1600 processors across 34 water-cooled super-nodes on a modified InfiniBand QDR fabric, 14th on the November 2011 TOP500 at a measured 741 MFlops/W. IEEE Spectrum's independent reporting names the same vendor, processor and water-cooling approach TOP500 records, though it describes the fabric only as 'a modified InfiniBand interconnect system' without naming the generation, so the interconnect edge here rests on TOP500 alone. No operating system was found on any source fetched for this pass. TOP500 is the only source for Rmax, Rpeak and core count, so the 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.

Cited source	Result	Found on the page
spectrum.ieee.org	names system and part	ShenWei SW1600, Mellanox InfiniBand QDR
top500.org	names system and part	ShenWei SW1600, Mellanox InfiniBand QDR
