ForHLR II
Operated by Karlsruhe Institute of Technology .
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.
| Role | Part | Supplier at build | Quantity | Confidence | Source |

The read
Lenovo NeXtScale nx360M5 research cluster of Xeon E5-2660v3 10-core processors on InfiniBand EDR/FDR at KIT's Steinbuch Centre for Computing, officially put into operation on 4 March 2016. TOP500 lists 22,960 cores, 0.77 PFlop/s Rmax, 0.96 PFlop/s peak and 435 kW, ranking it 127th in June 2016 and 442nd in June 2018. KIT's own account counts more than 1,170 nodes, over 24,000 cores and 74 TB of memory, with warm-water cooling, and a budget of about 26 million euros shared with the state of Baden-Wuerttemberg. The SCC web pages now file it under former HPC systems beside the successor HoreKa, with no shutdown date on the pages fetched, so none is recorded. No site is recorded because the pages fetched do not place the machine in a named building. TOP500 is the only source for Rmax.

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.
