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
Cluster of the Poznan Supercomputing and Networking Center (PCSS, the Polish name for PSNC), installed in 2024. TOP500 lists it as an HPE Cray XD220v / HPE Cray XD665 system with AMD EPYC 9334 32-core 3 GHz and Intel Xeon Platinum 8480+ 56-core 2 GHz processors on InfiniBand NDR200 under Rocky Linux 9.3: 58,224 cores, Rmax 13.82 PFlop/s, Rpeak 23.32 PFlop/s, with no accelerator named in the TOP500 record. PCSS names the same HPE Cray XD220v and XD665 models, the two processor families and NDR200 InfiniBand in its TOP500 news item and says Proxima is a key element of the national PRACE-LAB 2 project (July 2020 to December 2023, Smart Growth operational programme). It ranked 93rd on the November 2024 list and 147th on June 2026; no power figure is published in the TOP500 record.

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 |
|---|---|---|
| top500.org | names system and part | AMD EPYC 9004 (Genoa), NVIDIA InfiniBand NDR (Quantum-2) |
