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.

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 Toronto and SciNet's national system for the Digital Research Alliance of Canada, launched on 7 August 2025 to replace Niagara and Mist. SciNet describes 1,224 CPU nodes (AMD Turin) and 63 GPU nodes with four NVIDIA H100 80GB GPUs each (252 in total), 768 GB of RAM per node, 400/800 Gb/s NDR InfiniBand, 29 PB of VAST NVMe storage and about 1,700 kW, with roughly 34 petaflops theoretical peak. TOP500 lists the GPU partition (Lenovo ThinkSystem SD665-N V3, EPYC 9654 hosts) at 37,440 cores, Rmax 9.49 PFlop/s and Rpeak 16.52 PFlop/s, 175th on the November 2025 list and 197th on June 2026; the separate CPU partition also ranks and is not counted here.

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.
