OzSTAR (2018)
Also known as OzSTAR P100 cluster
Operated by Swinburne University of Technology at Swinburne University (OzSTAR) .
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.

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 previous-generation OzSTAR supercomputer at Swinburne, installed in 2018 for the OzGrav gravitational-wave centre and other astronomy and data-intensive work, and still running beside the newer Ngarrgu Tindebeek. Swinburne's documentation lists 4,140 CPU cores and 230 GPUs: 107 standard nodes with two 18-core Intel Gold 6140 CPUs, 192 GB of RAM and two NVIDIA P100 12GB each, plus 8 high-memory nodes with 384 to 768 GB and 2 TB of NVMe, all on 100 Gbps Intel Omni-Path. A 2025 arXiv survey lists Swinburne's combined OzSTAR and Ngarrgu Tindebeek estate at 15,860 cores and 300 GPUs. Swinburne's page does not name the integrator, and no FLOPS figure or TOP500 entry was found.

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 | - |
| supercomputing.swin.edu.au | names system and part | Omni-Path Architecture |
