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
Third-generation Magic Cube at the Shanghai Supercomputer Center: a Sugon TC6000 cluster of Xeon Gold 6142 hosts with NVIDIA Tesla V100 GPUs on Intel Omni-Path. It entered the TOP500 at 133rd in June 2019 and stayed listed to November 2023, succeeding Magic Cube (2008) and Magic Cube II (2015).

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 |
|---|---|---|
| top500.org | names system and part | NVIDIA Tesla V100, Omni-Path Architecture |
