amplitUDE
Operated by University of Duisburg-Essen at UDE Duisburg Campus .
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 Duisburg-Essen's MEGWARE supercomputer, whose GPU partition was benchmarked in 2023 and placed eighth on the June 2023 Green500 at 51.3 GFlops/Watt. TOP500 lists the GPU partition at 6,768 cores, 1.95 PFlop/s Rmax and 37.98 kW (Xeon Platinum 8480+, H100 80GB PCIe, InfiniBand NDR, ranked 483rd in June 2023). The university's page describes the installed machine as 240 CPU nodes and 19 GPU nodes (17 with four and 2 with two H100), 2.1 PB of Lustre and NDR200 InfiniBand, in place since mid-2024 with official operation from early December 2024.

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 H100 80GB PCIe, NVIDIA InfiniBand NDR (Quantum-2) |
| uni-due.de | names system and part | NVIDIA H100 80GB PCIe, NVIDIA InfiniBand NDR (Quantum-2) |
