Operated by University of Leeds .
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 |
|---|---|---|---|---|---|
| Integrator | - Dell Technologies R6625 and R7615 servers | Dell Technologies | - | Reported | arcdocs.leeds.ac.uk |
| Accelerator | NVIDIA L40S Accelerators CUDA (Ada Lovelace) · 350 W NVIDIA L40S 48GB PCIe, 3 per node on 28 GPU nodes, 84 GPUs | NVIDIA | 84 reported | Reported | arcdocs.leeds.ac.uk |

The read
Aire is the University of Leeds HPC facility, launched on 6 February 2025 and replacing ARC3 and ARC4, which are now retired. The compute-node page lists 52 standard nodes and 2 high-memory nodes (Dell R6625, dual 84-core AMD EPYC 9634, 168 cores each) and 28 GPU nodes (Dell R7615, 3x NVIDIA L40S 48GB PCIe, 24-core EPYC 9254), stated as 84 GPU cards in total. The 9,744 core figure is our sum of node counts times cores per node. Leeds lists a retirement date of 31 July 2029 and notes an upcoming Aire upgrade. 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.
