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
Sunbird is the Supercomputing Wales system hosted at Swansea University for Swansea and Aberystwyth users. The Supercomputing Wales portal gives its specification as 126 nodes, 5,040 cores and 48.384 TB of RAM, with 2x Intel Xeon Gold 6148 (20 cores each) and 384 GB per node, 8 NVIDIA V100 GPUs, 808 TB of Lustre scratch and 231 TB of Lustre home space. Partitions are 122 general compute nodes and 4 GPU nodes. Operator documentation only, 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.
