Shaheen III
Operated by KAUST at KAUST Supercomputing Core Lab .
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 only system in this dataset outside North America, Europe and East Asia, which is itself the finding: sovereign compute programmes are concentrated in a small number of places, and a directory that only covers the top of a ranking makes that concentration invisible by treating it as the whole world. This row is the CPU partition; a later, separate GPU partition with its own HPL submission carries its own row, shaheen-iii-gpu, matching the split TOP500 itself uses for the same physical KAUST installation.

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 | AMD EPYC 9004 (Genoa), HPE Slingshot-11, HPE Cray Operating System, HPE Cray ClusterStor E1000 |
