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.
| Role | Part | Supplier at build | Quantity | Confidence | Source |

The read
CyberAgent's in-house machine-learning platform, a Kubernetes-based GPU as a Service environment listed on the TOP500 as a Dell PowerEdge XE9680 system with Intel Xeon Platinum 8480+ 56C hosts, NVIDIA H100 GPUs, 400 Gb Ethernet and Ubuntu 22.04.5, 37,376 cores, Rmax 10.82 PFlop/s and Rpeak 16.97 PFlop/s at rank 132 on June 2025, 154 on November 2025 and 174 on June 2026. A CyberAgent engineer's June 2023 hardware deck describes the platform as DGX/HGX H100 nodes (80 H100 GPUs at that date) with 400 GbE RoCEv2 and NetApp all-flash storage in a Tokyo-based facility; the TOP500 run is a later configuration, so the 2023 count is not applied to it. TOP500 gives no install year here, so the operational date is left open.

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 |
|---|---|---|
| speakerdeck.com | names system only | - |
| top500.org | names system and part | Ubuntu Server |
