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
NSF-funded ($10 million, announced 1 June 2020) national research cloud led by Indiana University with Dell hardware and AMD EPYC Milan processors, quoted at about 8 aggregate petaFLOPS. The Jetstream2 docs list 384 standard nodes (128 cores, 512 GiB), 32 large-memory nodes (1 TiB), and 154 GPU nodes holding 360 NVIDIA A100 40 GB, 96 H100 80 GB and 32 L40S GPUs, 14 PB of Ceph and 4 x 100 Gbps to Internet2. The cores figure counts the standard and large-memory nodes only (49,152 plus 4,096) and excludes GPU-node hosts. IU names ASU, Cornell, University of Hawai'i and TACC as partner sites; the primary system is at IU Bloomington.

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.
