Eole
Operated by EDF .
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: 1263 of 1345 systems have a readable citation that names them, and 56 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
EDF's Bull cluster of Intel Xeon E5-2680v4 14C 2.4GHz processors on Intel Omni-Path, 29,568 cores at 942.83 TFlop/s Rmax and 1.14 PFlop/s Rpeak on 420.87 kW, running Linux. TOP500 lists the site simply as EDF. It debuted at rank 129 on the November 2016 list and last appeared at rank 460 on November 2018, which is the basis for the status date; no retirement notice was found.

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 |
