Vestas1
Operated by Vestas Wind Systems .
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
Vestas's 2016 Lenovo NeXtScale nx360 M5 cluster of Xeon E5-2680 v3/v4 (14-core, 2.4 GHz) CPUs on InfiniBand FDR, 16,848 cores at 481.8 TFlop/s Rmax and 522.5 TFlop/s Rpeak, ranked 442nd on the June 2017 list, its only appearance. TOP500's Vestas site page also lists two earlier Vestas machines (a 2008 HP cluster and a 2011 IBM iDataPlex that reached rank 53), which are not in this dataset. TOP500 gives only the company, headquartered in Denmark, so no site is recorded. The machine supports wind-resource and turbine modelling, which TOP500 itself does not state.

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.
