Fritz
Also known as Fritz (NHR@FAU)
Operated by FAU Erlangen-Nuremberg at RRZE Erlangen .
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
MEGWARE parallel cluster at FAU Erlangen-Nuernberg's regional computing centre (NHR@FAU). The operator lists 992 Ice Lake nodes (two Xeon Platinum 8360Y, 72 cores each) plus 64 later Sapphire Rapids nodes on blocking HDR100 InfiniBand, with a 3.5 PB Lustre scratch file system. Measured 3.578 PFlop/s on 986 nodes in November 2022, 151st on that list; it first appeared on the June 2022 list at rank 323.

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 |
|---|---|---|
| doc.nhr.fau.de | names system and part | NVIDIA InfiniBand HDR |
| top500.org | names system and part | NVIDIA InfiniBand HDR |
