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
New York University's flagship general-purpose HPC cluster, built by Lenovo and installed from July 2020 with Lenovo Neptune direct water cooling; NYU's own news release says it was operational by October 2020. TOP500 lists it at 32,796 cores, 2.09 PFlop/s Rmax, 3.04 PFlop/s Rpeak and 511.54 kW on InfiniBand HDR (peak rank 215th, November 2020). NYU's HPC documentation lists 332 GPUs (NVIDIA RTX8000 and V100) and 7.3 PB of usable storage. The TOP500 page and the search snippet for it disagree on the exact Xeon model, so only the Cascade Lake generation is recorded. A separate 2024 expansion, Greene-H100 (Lenovo ThinkSystem SD665-N V3, AMD EPYC 9454, NVIDIA H100 80 GB, 9,360 cores, 2.44 PFlop/s Rmax per TOP500), is not part of these figures.

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 |
|---|---|---|
| research.stern.nyu.edu | names system only | - |
| top500.org | names system and part | NVIDIA InfiniBand HDR |
