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.

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
Edge was Livermore's unclassified visualisation and data-analysis cluster, described on LLNL's archived 2011 and 2013 pages as the only production resource at Livermore Computing with GPUs and as limited-access. Those pages list 216 nodes (2 login, 206 batch) with two six-core Xeon X5660 2.8 GHz CPUs each (2,592 CPU cores), 412 Tesla M2050 GPUs (two per compute node), 48 or 96 GB per node, InfiniBand QDR from Mellanox and fast links to the Lustre file systems. TOP500 lists the Appro GreenBlade cluster at 8,240 cores (GPU cores evidently counted), 100.5 TFlop/s Rmax, 239.87 TFlop/s Rpeak and 745 kW across six lists, 73rd in November 2010 to 470th in June 2013.
