LOEWE-CSC
Also known as LOEWE CSC cluster Frankfurt
Operated by Goethe University Frankfurt .
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
Goethe University Frankfurt's heterogeneous GPU cluster, 22nd on the November 2010 TOP500 with 15,120 cores, 285.2 TFlop/s Rmax and 469.7 TFlop/s Rpeak. TOP500 lists a Supermicro cluster built with Clustervision, AMD Opteron 6172 12-core 2.1 GHz CPUs, ATI Radeon GPUs and InfiniBand QDR. The Hessian competence centre HKHLR documents the AMD nodes as dual-socket 12-core Opteron 6172 machines and states that the LOEWE cluster has been switched off, with Goethe-HLR as its successor.

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 |
|---|---|---|
| hkhlr.de | names system only | - |
| top500.org | names system and part | Mellanox InfiniBand QDR |
