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.

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
Louisiana State University's Dell PowerEdge 1955 blade cluster. LSU's HPC page says Tezpur was delivered on 3 November 2006 and is a 15.3 TFlop/s peak cluster of 360 compute nodes, each with two dual-core 2.66 GHz Xeon processors, 4 GB of memory and a 10 Gb/s InfiniBand interface, running Red Hat Enterprise Linux 4, with 32 TB of Panasas disk and 21 TB of IBM GPFS storage. TOP500 lists 1,440 cores at 10.60 TFlop/s Rmax and 15.36 TFlop/s Rpeak, rank 134 in November 2007 and 345th in June 2008, its last appearance.

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 |
