Quriosity (2023)
Also known as BASF Quriosity
Operated by BASF at BASF Ludwigshafen Site .
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.

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
BASF's second Quriosity, built by HPE with AMD processors and more than 1,000 compute nodes, announced on 25 May 2023 at the Ludwigshafen site as roughly twice as fast as its 1.75 PFlop/s predecessor. BASF states 3 PFlop/s without saying whether that is peak or sustained, so it is recorded here as an operator-stated Rpeak; no TOP500 entry exists. The release also cites 3,000 TB of storage and warm-water cooling that absorbs heat directly at the source, and names its workloads as personal-care product modelling, chemical process optimisation, crop-protection development and plant fluid dynamics, with more than 400 users and about 20,000 jobs per day on the earlier system. BASF's release and Computer Weekly independently agree on HPE, AMD CPUs and 3 PFlop/s; the exact CPU model and core count are not published.

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.
