Navigator (LCA-UC)

Also known as Navigator, Navigator+

Operated by LCA-UC at University of Coimbra (LCA) .

Researched with AI assistance, checked by scripts. These rows were researched by AI agents reading public operator, laboratory and vendor sources, appended by scripts and checked by automated validation; no subject-matter expert has reviewed them (how this site is made). A mechanical second-reader pass has since fetched every cited source: 1350 of 1581 systems have a readable citation that names them, and 64 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

The University of Coimbra's advanced-computing cluster, inaugurated in February 2019 in the Physics and Chemistry building according to the national network FCCN, which also reports a 2.17 million euro investment and 2021 upgrades to cooling and to the archiving and backup system. The RNCA page lists 192 nodes in three configurations, 3,936 plus 1,280 cores, 86 plus 161.2 TFlops of maximum processing capacity, 220 TB plus 1.27 PB of disk, InfiniBand FDR and EDR, and 8 Tesla V100 plus 2 A40 visualisation cards. The CPU families it names are Xeon E5-2697v2, Xeon Gold 6148 and, for some nodes, quad-socket Xeon Gold 6154. The SKA Observatory's partner page for LCA confirms V100 GPU nodes and a 72-core, 3 TB shared-memory system. The summed peak is not entered as a single FLOPS figure because the pages give it only as two numbers. Navigator is a PRACE-linked Tier-1 resource per the FCCN article. Other Portuguese national machines in the dataset are Deucalion.
