Operated by University of Oxford at Hartree Centre Supercomputing Centre (Daresbury) .
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
The EPSRC-funded national GPU facility for machine learning and molecular dynamics, led from the Oxford e-Research Centre and run at the STFC Hartree Centre in Daresbury. The Oxford case study lists 63 DGX nodes with 504 NVIDIA V100 GPUs, Mellanox InfiniBand and DDN AI400 storage under a GBP 5 million four-year Atos contract; TOP500 lists it as a Bull system built on NVIDIA DGX-1 MaxQ nodes with Xeon E5-2698v4 20C hosts, V100 SXM2 GPUs and Mellanox HDR InfiniBand at 1.47 PFlop/s Rmax, 3.93 PFlop/s Rpeak and 113 kW. Its only TOP500 entry is November 2020 (456th), when it was 16th on the Green500 at 13.035 GFlops/Watt. Later status is not documented, so the row is carried as of that list.

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 |
|---|---|---|
| oerc.ox.ac.uk | names system only | · counts: 504 |
| top500.org | names system and part | NVIDIA Tesla V100 |
