Operated by NI-HPC at Queen's University Belfast (Kelvin2) .
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
The Northern Ireland HPC (NI-HPC) Tier 2 facility run by Queen's University Belfast and Ulster University. Alces Flight announced completed installation on 21 October 2020 with Dell EMC and ROC Technologies: 128-core AMD EPYC2 and Intel Xeon nodes, NVIDIA V100 GPUs, 100 Gb Mellanox InfiniBand and over 6 PB of tiered storage. HPC-UK lists 32 V100 GPUs at launch. NI-HPC's current documentation lists 109 AMD nodes, 8 V100 nodes, 3 A100 nodes plus one MIG A100 node, and single H100, MI300X and Intel Max 1100 nodes, with 8 high-memory nodes.

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 |
|---|---|---|
| hpc-uk.ac.uk | names system, part and count | NVIDIA Tesla V100 · counts: 32 |
