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
Hungary's national AI and HPC system, operated by KIFU (the Governmental Information Technology Development Agency) at its Supercomputer Center on the Kassai ut campus of the University of Debrecen. TOP500 lists it as an HPE Cray EX system with AMD EPYC 7763 64-core CPUs, NVIDIA A100 SXM4 40GB GPUs and a Slingshot-11 fabric, at 3.10 PFlop/s Rmax and 4.51 PFlop/s Rpeak across 27,776 cores and 110.24 kW. The University of Debrecen's own news page independently confirms KIFU as operator, the Debrecen campus site, an aggregate performance in the same few-petaflops range, a dedicated AI partition alongside a general HPC partition (hence workload_class mixed), and a build timeline of assembly in September 2022, testing in October 2022 and expected operation by December 2022, but it does not restate TOP500's precise Rmax, Rpeak or hardware SKUs, so those figures rest on TOP500 alone and the row stays reported. Komondor's current TOP500 listing is on the June 2026 edition, whose list_appearances pointer budget is already full per LEGAL.md's 50-row cap, and no earlier edition with a specific rank for this system could be confirmed from a directly-fetched source, so ranked is left 0 and no list_appearances row is recorded even though the system is genuinely TOP500-listed.

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.
