Unayzah (2017)
Also known as Unayzah
Operated by Saudi Aramco .
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: 1263 of 1345 systems have a readable citation that names them, and 56 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 2017 Lenovo NeXtScale nx360M5 and x3550 M5 cluster of Xeon E5-2680v4 14C 2.4GHz processors on 10G Ethernet, running Linux: 41,832 cores at 484.5 TFlop/s Rmax and 1,606.35 TFlop/s Rpeak. Its only TOP500 appearance was rank 438 on June 2017, which is the basis for the status date. TOP500 names it Unayzah; whether it is an ancestor of the later Unaizah and Unizah systems already in this dataset is not stated in the sources fetched.

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 |
