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

SGI ICE X system at the Air Force Research Laboratory DoD Supercomputing Resource Center, part of the DoD HPC Modernization Program. SGI's 2013 launch announcement describes 2,304 compute blades with 9,216 Xeon E5-2600 (2.6GHz) sockets and 73,728 cores, 144TB of memory, over 1.5 PFlop/s theoretical peak and 6.72 PB of SGI InfiniteStorage 5500 running Lustre; a May 2012 trade report gives the contract value as 27.8 million US dollars. TOP500 lists the system as 73,584 cores of Xeon E5-2670 8C 2.6GHz on InfiniBand FDR with Red Hat Enterprise Linux 6, Rmax 1.41547 and Rpeak 1.53055 PFlop/s at 1,606 kW, ranked 15th in June 2013 and last listed 471st in November 2020; an initial 18,432-core configuration first ranked 69th in November 2012. The press release describes it as ranked 14th at deployment.

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.
