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
Idaho National Laboratory's Wind River supercomputer, named for the Wind River Range in Wyoming and a CTS-2 class machine. INL's HPC page lists it as arrived in 2024 with 20 racks, 843 nodes, 94,416 cores, 5.3 PFLOPS and an Omni-Path (OPA) interconnect. TOP500 lists WindRiver CTS-2 as a Dell PowerEdge (CTS-2) system with Xeon Platinum 8480+ 56C 2GHz hosts on Intel Omni-Path under Rocky Linux 8, installed 2025, with the same 94,416 cores, Rmax 5.33 PFlop/s, Rpeak 6.04 PFlop/s and 893.4 kW (level 1); it debuted at rank 234 on the June 2025 list and was 291st in June 2026. The two sources agree on cores, performance and interconnect, so the tier is verified. INL gives the arrival year 2024 and TOP500 the install year 2025, so no in-service date is recorded, and INL's page lists a total memory figure that was not used. The campus is not stated, so the site is left blank.

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 |
