Huawei Cloud Wuhu CloudMatrix Supernodes
Also known as Huawei Cloud Wuhu Data Center CloudMatrix 384
Operated by Huawei at Huawei Cloud Wuhu Data Center .
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
Huawei Cloud's CloudMatrix 384 supernodes in its Wuhu, Anhui data center. Huawei Cloud unveiled the product on 10 April 2025 at its ecosystem conference in Wuhu and announced large-scale deployment at the Wuhu data center; Light Reading (17 April 2025) reports the system as already running there. Each supernode joins 384 Ascend 910C NPUs and 192 Kunpeng CPUs over an all-to-all optical Unified Bus (Baidu Baike gives 300 PFlops per supernode). The number of supernodes in Wuhu and the site power are not published, so no site-level FLOPS or accelerator count is recorded. Baidu Baike also lists Ulanqab and Gui'an as deployment sites; Ulanqab is recorded separately and Gui'an is not yet added because only that one page names it.

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 |
|---|---|---|
| baike.baidu.com | names system and part | Huawei CloudMatrix 384 |
