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 | - SGI ICE X (TOP500 manufacturer field: HPE) | SGI HPENYSE

The read
An SGI ICE X cluster at the SENAI CIMATEC Supercomputing Centre in Salvador, Bahia, and the earlier of its two TOP500 systems. TOP500 lists 17,200 cores of Xeon E5-2690v2 10C 3GHz with InfiniBand FDR on Red Hat Enterprise Linux 6.5, 405.36 TFlop/s Rmax and 412.80 TFlop/s Rpeak; it debuted at rank 96 on the June 2014 list and was last listed at rank 434 in November 2016, which is the basis for the status date. TOP500 also shows a 2,580 kW power figure that looks inconsistent with a 413 TFlop/s machine, so no power is recorded. SENAI CIMATEC's article confirms it was previously on the TOP500 list.

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 |
|---|---|---|
| top500.org | names system and part | Intel Xeon E5-2690 v2, Mellanox InfiniBand FDR |
