Researched with AI assistance, checked by scripts. These rows were researched by AI agents reading public operator, laboratory and vendor sources, appended by scripts and checked by automated validation; no subject-matter expert has reviewed them (how this site is made). A mechanical second-reader pass has since fetched every cited source: 1350 of 1540 systems have a readable citation that names them, and 64 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
CSC's general-purpose HP supercluster for small and medium jobs and memory-heavy work, installed alongside the Cray system Sisu (sisu). CSC's slides list 576 HP ProLiant SL230s servers with 1,152 Xeon E5-2670 2.6 GHz CPUs (9,216 cores), 64 GB per server, 18 high-memory servers (two with 1.5 TB, sixteen with 256 GB), Mellanox FDR InfiniBand and 190 TF peak, growing to about 515 TF in 2014/15 after a hot-water-cooled Bull prototype (90 Xeon Phi 7120X, 72 Tesla K40, 240 TF) was integrated; the same deck mentions the Pouta cloud service unveiled in April 2014. TOP500 lists 8,704 cores and 149.4 TF at rank 167 in Nov 2012, then 9,200 cores, Rmax 163.9 TF and Rpeak 191.36 TF from Jun 2013 (rank 211) to Nov 2014 (rank 424); 9,200 versus 9,216 cores is a minor mismatch. The listed figures do not include the later Bull partition.

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.
| Cited source | Result | Found on the page |
