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
GPU supercomputer of the RIKEN Center for Advanced Intelligence Project, built by Fujitsu. Launched in 2017 with 24 NVIDIA DGX-1 (Tesla P100) servers (TOP500 entry 307th in June 2017), then upgraded in April 2018 to 54 DGX-1 Volta servers (432 Tesla V100 GPUs), about 54 PFLOPS of mixed-precision deep learning performance, plus 64 PRIMERGY CX2550 M4 CPU servers. The Volta subsystem ranked 171st on the June 2018 TOP500 (35,360 cores, 1.21 PFLOPS Rmax); this row records that configuration. Status as of is the last TOP500 list it appeared on.

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, NVIDIA Tesla P100, Mellanox InfiniBand EDR |
| top500.org | names system and part | NVIDIA Tesla V100, NVIDIA Tesla P100 |
