Researched with AI assistance, checked by scripts. These rows were researched by AI agents reading public operator, laboratory and vendor sources, appended by scripts and checked by automated validation; no subject-matter expert has reviewed them (how this site is made). A mechanical second-reader pass has since fetched every cited source: 1350 of 1540 systems have a readable citation that names them, and 64 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 |

| CPU | - Intel Pentium 4 Xeon (Prestonia) 2.4 GHz, 384 benchmarked processors | Intel | 384 reported | Reported | top500.orgscholarworks.iu.edu |

The read
IBM Xeon Linux cluster of the NSF-funded AVIDD facility (Analysis and Visualization of Instrument-Driven Data) at Indiana University, listed by TOP500 as AVIDD-B plus AVIDD-I, the Bloomington and Indianapolis halves: 384 Pentium 4 Xeon 2.4 GHz cores, Myrinet and Force10 networking, Rmax 1,058 and Rpeak 1,843 GFlop/s, rank 50 in June 2003, 114 in November 2003, 218 in June 2004 and 337 in November 2004 (https://www.top500.org/system/172590/). The project's final report to NSF (award EIA-0116050, 1 September 2001 to 31 August 2003) says AVIDD is a quartet of IBM Linux clusters with 470 processors and 2.2 TFlop/s aggregate peak: two clusters of 208 Prestonia 2.4 GHz processors each (the Bloomington and Indianapolis sites), a 36-processor 64-bit McKinley cluster for computer science research, and an 18-processor 1.3 GHz Pentium III cluster at IU Northwest, plus 10 TB of disk. It states that AVIDD ranked 50th on the June 2003 Top500, the highest-ranked distributed Linux cluster on that list and the first distributed Linux cluster to document more than 1 TFlop/s on Linpack. The TOP500 core count (384) is lower than the 416 Xeon processors the report counts for the two main clusters, so only the benchmarked portion is in the flops figures. IU's later machine is big-red.
