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

The SGI ICE X supercomputer inaugurated on 13 July 2016 at COPPE/UFRJ's NACAD in Rio de Janeiro, installed by SGI partner Versatus HPC and billed as the most powerful machine in a Brazilian federal university at the time, 2.5 times the previous Galileu system on a third of the power. TOP500's news report gives 226 TFlop/s from 506 Xeon E5-2670 v3 12-core processors at 2.3GHz in 253 dual-socket servers (6,072 cores) with 16 TB of memory and three SGI InfiniteStorage 5600 arrays holding 720 TB under Intel Enterprise Lustre; the interconnect is not stated in the fetched pages. No TOP500 entry was found, so ranked is 0 and no Rmax is recorded; the 226 TFlop/s is the operator-stated capacity. It is part of Brazil's national SINAPAD HPC system. No retirement notice was found, but no current-status page was fetched, so the operational status is unconfirmed. TOP500 and COPPE are independent organizations but the second page confirms only the vendor, capacity and date, 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.
