Also known as CECI NIC5; NIC5 (University of Liege)
Operated by University of Liege at SEGI, University of Liege (Sart Tilman) .
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.
| Role | Part | Supplier at build | Quantity | Confidence | Source |
|---|---|---|---|---|---|
| CPU | - 73 nodes with two 32-core AMD EPYC Rome 7542 at 2.9 GHz, 4,672 cores in total (quantity is nodes) | AMD | 73 reported | Reported | ceci-hpc.becampus.uliege.be |

The read
A Tier-2 cluster of the CECI consortium hosted at the University of Liege SEGI facility (Sart Tilman), installed in January 2021 with funding from the F.R.S.-FNRS and aimed at MPI jobs with heavy communication or parallel I/O. CECI and ULiege list 73 nodes with two 32-core AMD EPYC Rome 7542 (2.9 GHz) each, 4,672 cores in total, 70 nodes with 256 GB and 3 nodes with 1 TB, a 100 Gbps HDR InfiniBand fabric (1.2:1 blocking) and 520 TB of BeeGFS scratch. The ULiege page quotes a peak of about 55 TFlop/s from its own arithmetic, which is inconsistent with the core count and clock, so no FLOPS figure is recorded.

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 |
