What is established
Operational. 24,000 accelerators (NVIDIA GH200); $587M announced investment; owned or developed by Forschungszentrum Jülich.
What is not disclosed
Capacity, timeline, named tenant, power source, cooling technology — not disclosed by any source on this page. Recorded as unknown, never as zero.
Analyst note
Europe's first exascale system, inaugurated September 2025 and in operation; funded 50% EuroHPC JU, 50% German federal/NRW. Capex includes six years of operations. A ~18 MW power figure circulates from TOP500 data but no quotable source was captured, so no MW is recorded.
Physical work is under way and the evidence includes a primary source.
