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.

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

bwForCluster for bioinformatics and astrophysics at the University of Tuebingen, built by MEGWARE. MEGWARE's 21 June 2016 announcement lists over 300 nodes, 236 dual-socket Xeon E5-2680v4 (Broadwell) nodes, 60 GPU nodes carrying 120 NVIDIA Tesla K80 cards, four quad-socket 1TB nodes and a 720TB BeeGFS parallel file system. TOP500 (June 2016, rank 414) lists 11,184 cores of Xeon E5-2680v4 14C 2.4GHz with Tesla K80 on InfiniBand FDR running Red Hat Enterprise Linux 7.2, Rmax 334.8 and Rpeak 534.1 TFlop/s at 151 kW. The two sources quote different core totals (MEGWARE 8,328 against 11,184 on TOP500), so the record is held at reported.

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.
