Alice Recoque
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.
| Role | Part | Supplier at build | Quantity | Confidence | Source |
|---|---|---|---|---|---|
| Integrator | - Eviden BullSequana XH3500 | Eviden | - | Reported | genci.frwww-hpc.cea.fr |
| Accelerator | AMD Instinct MI430X Accelerators AMD Instinct MI430X with 432 GB HBM4 | AMD | - | Reported | genci.frwww-hpc.cea.fr |

The read
France's EuroHPC exascale system, to be operated by CEA at its TGCC computing centre and built by Eviden as a BullSequana XH3500 with AMD EPYC Venice CPUs, Instinct MI430X GPUs, DDN storage and warm-water liquid cooling. EuroHPC selected the supplier in November 2025 for installation from 2026 and user access in 2027. GENCI states under 15 MW and over one exaflop of double-precision HPL; it has not run, so no FLOPS or rank is recorded. The GENCI and CEA pages share a joint release, so they are one source in effect and the tier is reported. The site is CEA's existing Bruyeres-le-Chatel entry, the nearest city-level match.

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 |
|---|---|---|
| www-hpc.cea.fr | names system and part | AMD Instinct MI430X, Direct liquid cooling, warm water |
