Marvin
Also known as Marvin tier 3 HPC cluster
Operated by University of Bonn .
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
The University of Bonn's tier 3 HPC cluster, purchased in October 2022 and operational since March 2024. The university's page lists 192 standard and 29 large-memory CPU nodes, 32 nodes with NVIDIA A100 80 GB GPUs for scalable applications, 24 A40 nodes for machine learning, 28,384 cores in total, a 5.6 PB Lustre filesystem and NDR 200 Gb/s InfiniBand. TOP500 lists the MEGWARE scalable GPU partition on AMD EPYC 7713 64C hosts with A100 SXM4 80 GB and InfiniBand NDR200 at 17,920 cores, 2.18 PFlop/s Rmax, 2.63 PFlop/s Rpeak and 90.74 kW, ranking 423rd on the June 2023 list (the same edition's Green500 rank was 34th at 23.330 GFlops/Watt) and 466th and 482nd on the next two. Only the GPU partition is carried in the FLOPS figures. The site is left blank.

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 7713 (Milan), NVIDIA InfiniBand NDR (Quantum-2) |
| hpc.uni-bonn.de | names system and part | AMD EPYC 7713 (Milan) |
