Corona

Also known as LLNL Corona

Operated by Lawrence Livermore National Laboratory at Livermore Computing Center .

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

Livermore Computing's unclassified Penguin cluster, listed by LLNL as 121 user-available nodes of 48 AMD Rome cores, 8 AMD MI50 GPUs and 256 GB each on InfiniBand HDR, sited in 2019 and available to the ASC, M&IC and CARES programs. Supermicro's October 2020 release describes the CARES Act expansion as nearly 1,000 Radeon Instinct MI50 GPUs in 4U 8-GPU servers with EPYC 7002 CPUs, giving up to 11 PFlop/s, which is the only peak figure and is vendor-stated, not HPL. The cluster has no TOP500 entry, so no Rmax is recorded. No core count or power figure is published on the pages fetched.

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.
