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
NYU Langone Health GPU cluster for healthcare AI. The TOP500 entry recorded here (June 2025, rank 225) lists an NVIDIA DGX H100 configuration with Xeon Platinum 8480C processors, H100 80GB GPUs on HDR InfiniBand, 18,688 cores, 5.56 PFlop/s Rmax and 8.74 PFlop/s Rpeak; the same name carried earlier A100 and H100 PCIe PowerEdge entries from 2023 and later ranked 280th in June 2026. The HPC Core page describes an HDR InfiniBand cluster with V100 and A100 GPUs and 14 PB of persistent storage, and a trade-press article cites 197 nodes, 646 GPUs and 15 PB of active storage, calling it the only TOP500 system dedicated to healthcare.

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 |
|---|---|---|
| med.nyu.edu | names system and part | NVIDIA InfiniBand HDR |
| top500.org | names system and part | Intel Xeon Platinum 8480C, NVIDIA InfiniBand HDR |
