Neolith
Also known as NSC Neolith HP cluster
Operated by NSC at NSC Data Centre, Linkoping .
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.

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 |
|---|---|---|---|---|---|
| Integrator | - HP Cluster Platform 3000 DL140 | Hewlett Packard Enterprise | - | Reported | top500.orgnsc.liu.se |
| CPU | - Intel Xeon E5345 quad-core 2.33 GHz | Intel | - | Reported | top500.org |
The read
NSC's main academic cluster between Monolith and Triolith: an HP Cluster Platform 3000 DL140 of Xeon E5345 quad-core 2.33 GHz CPUs on InfiniBand. NSC's history page says Neolith replaced Monolith in 2007 and debuted 23rd on the TOP500; the TOP500 system page recorded here shows the 6,440-core configuration on six lists from November 2008 (56th, 47.03 TFlop/s Rmax, 60.02 TFlop/s Rpeak) to June 2011, so the 2007 placing was presumably an earlier smaller configuration that TOP500 lists separately. The retirement date was not found; the status date is the last list 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.
