Operated by University of Colorado Boulder .
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.
| Role | Part | Supplier at build | Quantity | Confidence | Source |
|---|---|---|---|---|---|
| Accelerator | - NVIDIA A100 (36), H200 (32), RTX Pro 6000 (32), L40 (9) and Grace Hopper GPUs | NVIDIA | - | Reported | curc.readthedocs.io |
| Accelerator | - AMD MI100 GPUs, 8 nodes with 3 each | AMD | 24 reported | Reported | curc.readthedocs.io |
| CPU | - AMD Milan and newer AMD CPU nodes | AMD | - | Reported | curc.readthedocs.io |
| Interconnect | NVIDIA InfiniBand HDR Interconnect Fat tree or dragonfly+ · 200 Gb/s per port · About 0.6 microseconds HDR-100 InfiniBand (200 Gb inter-node fabric) | NVIDIA | - | Reported | curc.readthedocs.io |
The read
A heterogeneous HPC cluster run by the University of Colorado Boulder Research Computing group with contributed hardware from CU Boulder, CU Anschutz and Colorado State University, funded in part by National Science Foundation award 2201538. The hardware page lists 489 compute nodes: AMD Milan and newer AMD CPU nodes plus 36 NVIDIA A100, 24 AMD MI100, 32 NVIDIA H200, 32 NVIDIA RTX Pro 6000, 9 NVIDIA L40 and 2 Grace Hopper GPUs, with HDR-100 InfiniBand (200 Gb inter-node fabric). The page gives per-contributor tables and no single core total, so cores are left blank. Both cited pages are Research Computing documentation, so confidence stays reported. No benchmark FLOPS are published.

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 |
|---|---|---|
| curc.readthedocs.io | names system and part | NVIDIA InfiniBand HDR |
| curc.readthedocs.io | names system only | - |
