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

TACC's interactive visualization and data-analytics resource, announced 19 Nov 2013 with HP and NVIDIA for deployment in January 2014 to replace Longhorn (longhorn) and complement Stampede (stampede). The announcement describes 132 HP ProLiant SL250s Gen8 compute nodes plus 14 management, login and Lustre-router servers in five racks; each compute node has two 10-core Xeon E5-2680 v2 CPUs, one NVIDIA Tesla K40, 256 GB of DDR3-1866 memory and Mellanox FDR InfiniBand, attached to the 20 PB Stockyard global file system. The TOP500 entry (Jun 2014 rank 397, Nov 2014 rank 474) lists 4,620 cores, Rmax 158.1 TF and Rpeak 247.9 TF and points to TACC's Maverick user guide. The announcement gives January 2014 as the planned deployment month and no later page confirmed the production date, so only the year is recorded.

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.

Cited source	Result	Found on the page
