Prometheus
Also known as Cyfronet Prometheus
Operated by Cyfronet AGH at Cyfronet AGH, Krakow .
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 |

The read
Cyfronet AGH's flagship HP Apollo 8000 cluster in Krakow, launched in 2015 and later expanded with Skylake nodes, NVIDIA Tesla K40, K80 and V100 accelerators and Xeon Phi cards. TOP500 lists Intel Xeon E5-2680v3 12C 2.5GHz processors with NVIDIA Tesla K40 over InfiniBand FDR, Rmax 1.67 PFlop/s, Rpeak 2.35 PFlop/s, 55,728 cores and 807.6 kW; it ranked 49th on the June 2015 list and peaked at 39th in November 2015, staying listed until 475th in June 2022. Cyfronet's page describes 2.65 PFlops peak and 53,748 cores in its final configuration, says it was on the TOP500 15 times in a row, and marks it decommissioned; no decommissioning date appears in a fetched source, so none is recorded. The differing core counts reflect different configurations, 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.
| Cited source | Result | Found on the page |
|---|---|---|
| top500.org | names system and part | Mellanox InfiniBand FDR |
| cyfronet.pl | names system and part | Mellanox InfiniBand FDR |
