Galileo
Also known as CINECA Galileo (2015)
Operated by CINECA at CINECA Casalecchio di Reno .
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.

The read
CINECA's Italian Tier-1 IBM/Lenovo NeXtScale cluster, bought jointly by INFN and the University of Milano-Bicocca with CINECA hosting. CINECA's news page gives 516 nodes of Haswell CPUs, 768 Intel Xeon Phi 7120P and 80 NVIDIA K80 accelerators and over 1 PFlop/s, and TOP500 lists 50,232 cores of Xeon E5-2630v3 with Phi 7120P, 0.68 PFlop/s Rmax and 1.10 PFlop/s peak, ranking it 105th in June 2015 and 397th in November 2017. CINECA's hardware page says it was in full production from February 2015 to 20 November 2017, was later reconfigured with newer processors and was gradually turned off from March 2021 to make room for Galileo100, which is why March 2021 is used as the end date. Wikipedia places it in Casalecchio di Reno and gives 2,825.55 kW, matching TOP500's power figure. TOP500 is the only source for Rmax.

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.
