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.

The read

Total Exploration Production's SGI Altix ICE 8200EX cluster for seismic imaging in Pau, France: 10,240 Xeon E5450 4C 3GHz cores on InfiniBand, SUSE Linux, 106.1 TFlop/s Rmax and 122.88 TFlop/s Rpeak on 442 kW. Oil IT Journal (June 2008) describes the purchase of a 10,240-core SGI Altix ICE with 123 TFlop/s of compute bandwidth, 500 TB of SGI InfiniteStorage and a Sun Lustre-based distributed file system for Total geophysicists in Pau, and says it ranked 10th on the June 2008 TOP500 (TOP500 now lists rank 11). Le Monde Informatique names Rostand as the 2008 machine that Pangea replaced in 2013; the name link to this TOP500 entry is an inference from the shared year, site and operator, which is why confidence is reported. Last appeared at rank 426 on June 2013, which is the basis for the status date.

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.

Every source cited on this page was readable, and none of them mentions this system. They are cited at page granularity, normally because no stable deep link could be found. That is a real weakness in this row and it is why the system carries a confidence tier below verified. See how this check works.
