Beaufix

Also known as Meteo-France Beaufix; Beaufix2

Operated by Meteo-France at Meteo-France Computing Centre (Toulouse) .

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.

Measured performance

Rmax: 2.16 PFlop/s
Rpeak: 2.59 PFlop/s
Rmax ÷ Rpeak: 83.5%
Cores: 73,440
Power: 830.2 kW
Per watt: 2.6 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

The research and development half of the first scalar supercomputer pair that Meteo-France bought from Bull, a bullx DLC cluster at the Meteopole in Toulouse that replaced the agency NEC vector machines. Meteo-France staff describe Beaufix as a Bull cluster of 1,008 compute nodes in 72-node racks, the development and research machine, with Prolix as its operational twin at another site; Scientific Computing World reported the first bullx DLC system installed in Toulouse with a 500 TFlop/s Linpack result on Intel Xeon E5-2600 v2 processors with direct liquid cooling, and Clubic reported the November 2012 order of about 1 PFlop/s for 2013 to 2014 rising above 5 PFlop/s by 2016. TOP500 lists the 2013 machine as Beaufix (Bullx DLC B710, Xeon E5-2697v2 12-core 2.7 GHz, InfiniBand FDR, 24,192 cores, 469 TFlop/s, 391 kW) from the November 2013 list at rank 62, and a 2016 expansion as Beaufix2 (bullx DLC 720, Xeon E5-2698v4 20-core 2.2 GHz, 73,440 cores, Rmax 2.16 PFlop/s, 830 kW, TOP500 system 178962), last listed in November 2020; the figures recorded are those of the expanded Beaufix2. The Taranis and Belenos pair (already in this dataset) was installed in 2020. The two independent sources (Meteo-France and TOP500) agree on the vendor, name, site and size.

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.
