Triolith

Also known as NSC Triolith HP SL230s 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: 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.

Measured performance

Rmax: 407.24 TFlop/s
Rpeak: 446.62 TFlop/s
Rmax ÷ Rpeak: 91.2%
Cores: -
Power: 519 kW
Per watt: 0.8 GF/W

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.

The read

NSC's flagship cluster from July 2012, an HP Cluster Platform 3000 of SL230s Gen8 nodes with Xeon E5-2660 8-core CPUs on Mellanox InfiniBand FDR, grown to 1,600 nodes by November 2013 and cut to 1,017 nodes in April 2017. NSC says it was retired on 21 September 2018 and replaced by Tetralith. TOP500 lists 25,376 cores and 407.24 teraflops Rmax, 95th on the June 2014 list; NSC counts 16,368 compute cores after the 2017 reduction, so no core count is recorded. TOP500 is the only source for Rmax and power, so the tier is reported.

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
nsc.liu.se	names system and part	Mellanox InfiniBand FDR
