Also known as LUMI AI Factory supercomputer
Operated by CSC at LUMI Data Center, Kajaani .
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.

The read
AI-optimised EuroHPC supercomputer for the LUMI AI Factory consortium (Finland, Czechia, Denmark, Estonia, Norway, Poland), contract signed with Bull on 31 August 2026 at 387.8 million euros split between EuroHPC JU and the consortium. It uses AMD Instinct MI430X GPUs and 6th generation 256-core AMD EPYC CPUs, expects a tenfold increase in AI capacity over LUMI, and will sit at CSC's data centre in Kajaani. Resultsense and TechTimes put operation in the second half of 2027 (EuroHPC says 2027); TechTimes also names IBM storage and Nokia networking and an MI430X FP64 rating of 288 teraFLOPS per GPU. GPU count, FLOPS and power are not published.

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.
