Hawk (Cardiff)
Also known as Supercomputing Wales Hawk
Operated by Cardiff University .
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
Hawk is the Supercomputing Wales system hosted at Cardiff University for Cardiff and Bangor users. The Supercomputing Wales portal gives its specification as 280 nodes, 12,736 cores and 68.224 TB of RAM, using 2x Intel Xeon Gold 6148 (20 cores each) and 2x AMD EPYC 7502 (32 cores each) nodes, plus 26 NVIDIA P100 GPUs on 13 nodes and 30 NVIDIA V100 GPUs on 15 nodes. Storage is 1,192 TB Lustre scratch and 420 TB of NFS home space. This is a different machine from the HLRS Hawk in Germany. 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.
Every source cited on this page was readable, and none of them mentions this system. They are cited at page granularity, normally because no stable deep link could be found. That is a real weakness in this row and it is why the system carries a confidence tier below verified. See how this check works.
| Cited source | Result | Found on the page |
