Operated by University of Queensland .
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 University of Queensland's flagship HPC cluster, supplied by Dell and launched in December 2022. The Research Computing Centre describes about 14,000 AMD EPYC Milan and Genoa cores (27,456 threads), 1.5 to 2 TB of memory per standard node and three 4 TB high-memory nodes, NVIDIA HDR InfiniBand at 200 Gbit/s per port, and GPU nodes using AMD Instinct MI2xx series, NVIDIA H100, and L40, L40S and A16 cards. The page gives no GPU totals; a 2025 arXiv survey of Australian institutions lists Bunya at 14,800 cores in 145 nodes and 114 GPUs including MI210 and MI300X. Bunya is co-located with the UQ node of the ARDC Nectar Research Cloud. No FLOPS figure is published.

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 |
|---|---|---|
| arxiv.org | does not name this system | - |
| rcc.uq.edu.au | names system and part | NVIDIA InfiniBand HDR |
