DeepComp 6800
Also known as DeepComp 6800 CNIC
Operated by CNIC, Chinese Academy of Sciences .
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.
| Role | Part | Supplier at build | Quantity | Confidence | Source |
|---|---|---|---|---|---|
| Integrator | - Lenovo built the DeepComp 6800 | Lenovo | - | Reported | top500.orgen.wikipedia.org |
| CPU | - Intel Itanium 2 1.3 GHz, 1,024 processors | Intel | 1,024 reported | Reported | top500.org |
| Interconnect | Quadrics QsNet Interconnect Fat tree · 340 MB/s per direction · About 2 microseconds Quadrics QsNet | Quadrics | - | Reported | top500.org |
The read
TOP500 lists the DeepComp 6800 at the Computer Network Information Center of the Chinese Academy of Sciences, built by Lenovo with 1,024 Intel Itanium 2 1.3 GHz processors on a Quadrics QsNet network running Linux, installed in 2003, 4.193 TFLOPS Rmax and 5.3248 TFLOPS peak, 14th on the November 2003 list page (used here) and still listed in June 2007. Wikipedia's Shanghai Supercomputer Center article describes DeepComp 6800 as China's most powerful supercomputer in November 2003 but gives the rank as 11th, which disagrees with the TOP500 list page; the Wikipedia page cites TOP500, so it is only partly independent. The tier is reported. The June 2007 list is the last evidence of operation.

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 |
|---|---|---|
| en.wikipedia.org | names system only | - |
| top500.org | names system and part | Quadrics QsNet |
