Also known as SDSC Voyager
Operated by SDSC at San Diego Supercomputer 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
NSF-funded experimental AI system at the San Diego Supercomputer Center built from 42 Supermicro X12 Gaudi training servers with 336 first-generation Habana Gaudi processors, plus two inference nodes carrying 16 Habana Goya cards. SDSC's user guide lists dual Xeon Gold 6336 hosts with 512 GB per training node, 6 x 400 Gb/s per node and a 1 PB Ceph file system, and says the system began a three-year testbed phase in early 2022. The UC San Diego story, written before launch, gives the same 336 and 16 processor counts and a five-year NSF grant. Both pages come from the same university, so the tier is reported. The SDSC page still describes the testbed phase, so the status date reflects that page rather than an allocation-phase announcement.

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.
