Blue Lion
Operated by LRZ at Leibniz Supercomputing Centre, Garching .
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 |
|---|---|---|---|---|---|

The read
LRZ's planned system, announced in June 2025 for 2027: an HPE Cray GX5000 with NVIDIA Vera Rubin and fanless direct liquid cooling with heat reuse, roughly 30 times SuperMUC-NG's performance, on a 250 million euro budget co-financed by the federal and Bavarian governments. NVIDIA's blog is its own account of the same announcement, so the tier is reported. Counts, power and FLOPS are not published.

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 |
|---|---|---|
| blogs.nvidia.com | names system and part | NVIDIA Vera Rubin, Direct liquid cooling, warm water |
