Operated by Karlsruhe Institute of Technology at KIT Scientific Computing Centre (Karlsruhe) .
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 |
|---|---|---|---|---|---|
| Accelerator | - NVIDIA H100 GPU nodes with four GPUs each (the two bwHPC pages differ on node count) | NVIDIA | - | Reported | wiki.bwhpc.denemo.uni-freiburg.de |

The read
The general-purpose entry-level HPC system of the universities and universities of applied sciences of Baden-Wuerttemberg, run by the Scientific Computing Centre of KIT and in operation since April 2025, free to all state researchers and students without a project proposal. The bwHPC wiki lists 272 Ice Lake CPU nodes (two Xeon Platinum 8358, 64 cores, 256 GiB), AMD EPYC 9454 standard and high-memory CPU nodes, NVIDIA H100 nodes with four GPUs each, one AMD MI300A node with four APUs, 15 Ice Lake nodes with four A100 or H100 GPUs and 19 Cascade Lake nodes with four A100 GPUs, on InfiniBand from HDR200 to 4x NDR200 with two parallel Lustre file systems and RHEL 9.4. The two bwHPC pages disagree on the AMD CPU and H100 node counts, so only the consistent figures are used and no core or peak figure is recorded.

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.
