VSC-3
Also known as Vienna Scientific Cluster 3
Operated by Vienna Scientific Cluster at Vienna Scientific Cluster .
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.
| Role | Part | Supplier at build | Quantity | Confidence | Source |
|---|---|---|---|---|---|
| CPU | - Intel Xeon E5-2650v2 8C 2.6GHz (Ivy Bridge), 2 per node | Intel | - | Verified | top500.orgzid.univie.ac.at |
| Interconnect | - Intel TrueScale InfiniBand (QDR) | Intel | - | Reported | top500.orgzid.univie.ac.at |
The read
Third system of the Vienna Scientific Cluster consortium: 2,020 dual-socket nodes of Xeon E5-2650v2 8-core processors, 32,768 cores, on QDR InfiniBand (TOP500 names Intel TrueScale) and cooled by submersion in synthetic oil across 23 cooling containers. TOP500 lists 596 TFlop/s Rmax, 681.57 TFlop/s peak and 450 kW, ranking it 85th at its November 2014 debut; the University of Vienna page quotes 584 TFlop/s peak and gives 2014 to 2022 as its operating life at the Arsenal in Vienna, which includes the later VSC-3 Plus extension of 864 nodes, so 2022 is used as the end date. TOP500 is the only source for Rmax.

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.
