Operated by University of Washington .
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 University of Washington's GPU-accelerated research computing platform. TOP500 lists it as a Dell PowerEdge XE9680 system with Intel Xeon Platinum 8462Y+ CPUs and NVIDIA H200 SXM5 141GB GPUs on NDR InfiniBand: 26,880 cores, Rmax 8.85 PFlop/s, Rpeak 12.87 PFlop/s and 144 kW under Rocky Linux 9.6, 185th on the November 2025 list and 207th on June 2026. The UW research computing page confirms H200 GPUs with multi-GPU, multi-node support but gives no node count; the data-centre site is not stated in the pages fetched.

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 |
|---|---|---|
| depts.washington.edu | names system and part | NVIDIA H200 SXM |
| top500.org | names system and part | NVIDIA H200 SXM, Intel Xeon Platinum 8462Y+, NVIDIA InfiniBand NDR (Quantum-2) |
