Neocortex
Also known as PSC Neocortex
Operated by PSC at Pittsburgh Supercomputing 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.
| Role | Part | Supplier at build | Quantity | Confidence | Source |

The read
PSC's NSF-funded AI testbed (initial $5 million award, announced 2020; early user program from March 2021). It pairs Cerebras wafer-scale systems with an HPE Superdome Flex of 32 Xeon Platinum 8280L processors, 24 TiB of RAM and 204.6 TB of NVMe, joined by 24 x 100 GbE links and 16 HDR-100 InfiniBand adapters. The system began with CS-1 and moved to CS-2; PSC now lists two CS-3 systems (WSE-3, 900,000 cores each), with NSF operations support extended to 31 May 2027. No FLOPS or TOP500 figure is published.

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.
