Afton (UVA)

Also known as Afton

Operated by University of Virginia .

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 University of Virginia's current-generation HPC system, run by UVA Research Computing alongside the older Rivanna cluster. The archived Research Computing page states 300 Afton compute nodes with 96 AMD EPYC 9454 cores each for 28,800 cores, at least 750 GB of memory per node, and shared access with Rivanna (603 nodes, over 20,476 cores) to 55 NVIDIA GPU nodes (RTX2080, RTX3090, A6000, V100, A40 and A100, including an NVIDIA BasePOD), over 8 PB of shared storage and a Michie North building location in Charlottesville. Only this one page was fetched (the live site returned 403), so confidence is reported and the page is an archive copy that may lag newer GPU additions. No benchmark FLOPS are published.

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.
