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.

The read
CINVESTAV's SGI ICE X cluster, installed in 2015 with 8,820 cores of Xeon E5-2697v3 14C 2.6GHz on InfiniBand FDR under SUSE Linux Enterprise Server 11, TOP500 manufacturer listed as HPE. It debuted on the June 2015 list at rank 255, its best placing, at 277.5 TFlop/s Rmax and 366.9 TFlop/s Rpeak, and was last listed at rank 370 on the November 2015 list, which is the basis for the status date; it is the only CINVESTAV system on TOP500. It is a separate machine from the older Xiuhcoatl hybrid cluster at the same institution. A web search summary of the project's own pages describes it as mixed CPU and GPU subsystems, but the project page itself could not be fetched, so only the TOP500 figures are recorded and the physical site is left unlocated. Both cited pages are TOP500 pages, so the tier is reported.

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.
