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 | - 36x Dell EMC PowerEdge C6420 CPU server units plus 9 C6400 chassis, 1,912 CPU cores | Dell Technologies | 36 reported | Reported | mif.vu.lt |

The read
Lithuania's principal academic HPC cluster at Vilnius University (Faculty of Mathematics and Informatics IT Research Center), open to national researchers and the base of the Lithuanian EuroCC competence centre. The faculty's own page lists 36 Dell EMC PowerEdge C6420 CPU nodes plus C6400 chassis, 3 NVIDIA DGX-1 (Tesla V100 32 GB) and 2 IBM Power9 AC922 (Tesla V100 32 GB) GPU servers, totalling 1,912 CPU cores, 17 TB RAM, 32 GPUs and 0.5 PB of storage on Mellanox EDR 100 Gbps InfiniBand. Integrator Novian Technologies' case study describes an earlier snapshot of the same cluster (1,728 CPU cores, 20,480 tensor cores, 13 TB RAM, 361 TFLOPS double precision, about 4 PFLOPS deep-learning), so counts differ by date and no FLOPS figure is recorded; install year is not published in the fetched pages. A future LitAI Factory (EuroHPC AI Factory, Vilnius) is a separate planned system and is not included.

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 |
|---|---|---|
| mif.vu.lt | does not name this system | NVIDIA Tesla V100, Mellanox InfiniBand EDR · counts: 32 |
| novian.io | names system and part | Mellanox InfiniBand EDR |
