Taurus
Also known as ZIH Taurus bullx DLC 720
Operated by TU Dresden at TU Dresden ZIH .
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.

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
TU Dresden ZIH's Taurus cluster, listed by TOP500 as a bullx DLC 720 with 34,656 Xeon E5-2680v3 12-core cores on InfiniBand FDR, 66th on the June 2015 list and its best rank. The ZIH HPC compendium archive describes Haswell islands of E5-2680 v3 nodes plus K80 GPU nodes and says Taurus was decommissioned by the end of 2023. The compendium counts only the islands it documents, so no core count beyond TOP500's is cited. TOP500 is the only source for Rmax, Rpeak, cores and power, so the tier is reported.

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 |
|---|---|---|
| compendium.hpc.tu-dresden.de | names system and part | Mellanox InfiniBand FDR |
