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
Louisiana State University's Dell cluster for LSU HPC, listed on the TOP500 at 250th in November 2012 (7,040 cores, Xeon E5-2670 8-core 2.6 GHz, QDR InfiniBand, 110.93 TFlop/s Rmax, 146.43 TFlop/s Rpeak, 200 kW) and 394th in June 2013. LSU HPC's Spring 2019 user-environment slides still list SuperMike II as a Dell cluster of 440 compute nodes, two 8-core 2.6 GHz Xeon CPUs per node, 50 nodes with two Nvidia M2090 GPUs each, RHEL 6 and a 146 TFlop/s peak. The TOP500 run used the 7,040-core CPU portion, so it excludes the GPU nodes. Last evidence is the 2019 slide deck.

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 | Intel Xeon E5-2670, Mellanox InfiniBand QDR |
| hpc.lsu.edu | does not name this system | - |
Checked 2026-10-09 by pnpm verify. Re-run it and the table changes with the web.
