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
Saudi Aramco's HPE Cray CS-Storm system of Xeon Gold 6248 CPUs and NVIDIA V100 GPUs on HDR100 InfiniBand, tenth on the November 2020 TOP500 and unveiled publicly in January 2021 with stc and its Solutions subsidiary. It is used for seismic imaging and deep-learning models of the subsurface. It was still listed at 96th in June 2026, which is the basis for the operational status. Aramco's release gives a peak of 55.4 PFlop/s, which agrees with TOP500 to rounding, but neither page states a node or GPU count, so no GPU quantity is recorded. The core count and Rmax come from TOP500 alone.

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 |
|---|---|---|
| aramco.com | names system only | - |
| top500.org | names system and part | NVIDIA Tesla V100, NVIDIA InfiniBand HDR |
