Caliburn
Also known as Rutgers Caliburn
Operated by Rutgers University .
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
New Jersey's most powerful academic supercomputer at the Rutgers Discovery Informatics Institute, designed by Manish Parashar and Ivan Rodero: 560 Supermicro FatTwin nodes, 20,160 Xeon E5-2695v4 cores, 140 TB DRAM, 218 TB NVMe and Intel Omni-Path at 677 TFLOPS peak, one of the first clusters on that fabric (Supermicro case study, October 2016). Rutgers says it was funded with 10 million dollars from the New Jersey Higher Education Leasing Fund (https://www.rutgers.edu/news/caliburn-new-jerseys-supercomputer-catalyzes-cutting-edge-research). TOP500 lists 0.60 PFLOPS Rmax and 896 kW, and it ranked 167th in June 2016. No retirement date appears in the pages we cited, so the status date is the data refresh.

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.
| Cited source | Result | Found on the page |
|---|---|---|
| top500.org | names system and part | Intel Xeon E5-2695 v4, Omni-Path Architecture |
| supermicro.com | does not name this system | - |
