Operated by NREL at NREL Golden Campus .
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 National Renewable Energy Laboratory's 8 PFlop/s HPE SGI 8600, installed in 2018 for energy-systems research with production use from January 2019: 2,114 dual-socket Skylake nodes with 96 to 768 GB memory on Mellanox EDR InfiniBand in an 8D hypercube, with 14 PB of storage and warm-water liquid cooling. TOP500 lists Xeon Gold 6154 18C 3GHz, 75,600 cores, Rmax 4.85 and Rpeak 7.26 PFlop/s, and shows it listed through November 2025. Named Eagle (NREL) to avoid confusion with Microsoft Eagle.

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 | Mellanox InfiniBand EDR |
| energy.gov | names system and part | Mellanox InfiniBand EDR |
