Operated by HSU Hamburg .
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.
| Role | Part | Supplier at build | Quantity | Confidence | Source |

The read
Hot-water-cooled Megware cluster at the Helmut-Schmidt-Universitaet in Hamburg, handed over on 7 December 2022. TOP500 lists 41,832 cores of Xeon Platinum 8360Y 36C 2.4GHz on InfiniBand HDR100, 2.13 PFlop/s Rmax, 3.21 PFlop/s Rpeak and about 400 kW running AlmaLinux 8.5; it ranked 339th in June 2022 (entry recorded here) and 500th in June 2024. The university states 581 nodes (five with GPUs), 149 TB of memory, 3.21 PFlop/s peak, 1 PB BeeGFS plus 1 PB Ceph storage, and 28th place in Germany at entry.

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 | NVIDIA InfiniBand HDR |
| hsu-hh.de | names system only | - |
