Gautschi AI
Also known as Purdue Gautschi-AI; Gautschi H100 partition
Operated by Purdue University at Purdue RCAC (West Lafayette) .
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 AI partition of Purdue's Gautschi cluster, run by the Rosen Center for Advanced Computing (RCAC): 20 Dell PowerEdge XE9680 nodes, each with eight NVIDIA H100 80GB GPUs (160 in total), two 56-core Intel Xeon Platinum 8480+ CPUs, about 1 TB of memory and 400 Gbps NDR InfiniBand. TOP500 lists the partition at 23,360 cores, Rmax 7.26 PFlop/s, Rpeak 10.86 PFlop/s and 168 kW under Rocky Linux 9; it first ranked 157th on the November 2024 list and 215th on November 2025. This record covers the AI (H100) partition only, not the separate Gautschi CPU partition.

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 | NVIDIA H100 SXM5, Intel Xeon Platinum 8480C, NVIDIA InfiniBand NDR (Quantum-2) |
| rcac.purdue.edu | names system and part | NVIDIA H100 SXM5, Intel Xeon Platinum 8480C, NVIDIA InfiniBand NDR (Quantum-2) |
