Operated by University of California, Los Angeles .

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

UCLA's campus-wide condominium HPC cluster, jointly launched in 2008 and now run by the Office of Advanced Research Computing. The system overview states 800+ 64-bit nodes and over 26,000 cores with over 179 TB of aggregate memory, 1, 10 or 25 Gb Ethernet plus QDR, FDR or EDR InfiniBand on each node, GPU cards on several nodes and eight petabytes of flash-based VAST storage. The governance page gives a slightly older 25,000-core, 174 TB description. Both pages are UCLA documentation, so confidence is reported, and the data center location is not stated so the system is left unlocated. 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.

None of the cited sources could be read from our network: the hosts returned bot challenges or did not respond. This check says nothing about the citations either way. See how this check works.
