Keeneland
Also known as Keeneland Full Scale System, KFS
Operated by Georgia Institute of Technology .
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
The Georgia Tech-led NSF Track 2D GPU system, a 264-node HP SL250 Gen8 cluster with two Sandy Bridge Xeons and three NVIDIA M2090 GPUs per node on Mellanox FDR InfiniBand, about 615 TFlop/s peak. Partners were the University of Tennessee-Knoxville, NICS and Oak Ridge National Laboratory, and it was made available through XSEDE. It reached 75th on the November 2012 TOP500 with 319.6 TFlop/s Rmax. The same TOP500 system entry earlier carried the smaller Keeneland Initial Delivery System of HP SL390s G7 nodes with Fermi GPUs, listed from November 2010.

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.
