TEIDE-HPC
Operated by ITER Tenerife .
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.

The read
Fujitsu PRIMERGY CX250 S1 cluster with Xeon E5-2670 8-core 2.6 GHz CPUs and InfiniBand QDR, installed by Atos and Fujitsu Spain for the Instituto Tecnologico y de Energias Renovables (ITER) in Tenerife. Fujitsu's December 2013 release puts it at 274 TFLOPS Rmax, the second most powerful supercomputer in Spain, with its power supplied partly by ITER-managed solar panels and wind turbines; TOP500 gives 273.97 TFLOPS, 16,384 cores and 312 kW. It debuted 139th on the November 2013 list and was 169th in June 2014. No retirement date appears in the pages we cited, so the status date is the data refresh.

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 |
|---|---|---|
| info.archives.global.fujitsu | names system only | - |
| top500.org | names system and part | Intel Xeon E5-2670, Mellanox InfiniBand QDR |
