Rudens
Operated by Riga Technical University at RTU HPC Center, Riga .
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 |

The read
Latvia's national academic HPC cluster, operated by the Riga Technical University HPC Center alongside the University of Latvia's Institute of Computational Modelling as part of the EuroCC national competence centre. RTU's own hardware manual lists 32 nodes (30 compute plus head/login), mixing AMD EPYC 9654 (Genoa) and EPYC 7713 (Milan) CPU-only nodes with GPU nodes carrying NVIDIA L40S, A100 and Tesla V100 accelerators (28 GPUs total) over InfiniBand ranging FDR to HDR 200Gb/s, for 2,736 CPU cores and a vendor-stated 240 TFlop/s combined peak (134 TFlop/s CPU plus 106 TFlop/s GPU). No HPL run has been published, so rmax is left blank and the peak figure is marked vendor_peak rather than hpl_measured; it does not appear on TOP500.

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.
