Operated by NASA at NASA Advanced Supercomputing Facility .

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

NASA Advanced Supercomputing's GPU system at Ames, named after a lunar south-pole crater. The NAS resource page lists 128 A100 nodes (one 64-core AMD EPYC 7763 and four A100 GPUs per node, 7.29 PFlop/s peak, InfiniBand HDR) plus 350 NVIDIA GH200 Grace Hopper nodes (72-core Grace CPU and H100 GPU each, 13.11 PFlop/s peak, InfiniBand NDR). NAS stories date the first A100 release to late December 2023 at about 5 PFlop/s, the GH200 installation to September 2024 and release to users in March 2025, and give 20.67 PFlop/s total peak after 57 V100 nodes migrated from Pleiades were added. The peak figure is NASA's own, so the basis is operator_stated. No TOP500 entry was found.

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.
