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
HPE Cray EX system at the Air Force Research Laboratory DoD Supercomputing Resource Center (AFRL DSRC) at Wright-Patterson AFB, part of the DoD High Performance Computing Modernization Program. TOP500 lists AMD EPYC 7H12 64C 2.6GHz processors over Slingshot-10 running SLES 15 SP2, installed 2021, with Rmax 4.03 PFlop/s, Rpeak 5.40 PFlop/s and 129,920 cores; it first appeared on the November 2021 list at rank 115 and was 349th in June 2026. TOP500 is the only fetched source for these figures, 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.
| Cited source | Result | Found on the page |
