Jade (ERDC)
Also known as ERDC DSRC Cray XT4 Jade
Operated by ERDC DSRC at ERDC DSRC (Vicksburg) .
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: 1263 of 1345 systems have a readable citation that names them, and 56 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
Cray XT4 at the Army Engineer Research and Development Center DoD Supercomputing Resource Center in Vicksburg, Mississippi. TOP500 lists Opteron quad-core 2.1GHz processors on the XT4 internal interconnect running Compute Node Linux, 8,464 cores, Rmax 56.25 TFlop/s, Rpeak 71.10 TFlop/s and 418 kW; it first appeared 29th on the June 2008 list and was last listed 372nd in November 2011. An ERDC DSRC hardware page captured by the Internet Archive in 2012 describes Jade as a Cray XT4 rated at 72.3 TFLOPS with 2,146 compute nodes of 4 AMD Opteron cores at 2.1 GHz on SeaStar2 under SUSE Linux CNL; the node-based core count (8,584) and peak do not exactly match TOP500's figures, so the tier is reported. Named Jade (ERDC) to distinguish it from LLNL, CINES and Oxford machines called Jade.

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.
Every source cited on this page was readable, and none of them mentions this system. They are cited at page granularity, normally because no stable deep link could be found. That is a real weakness in this row and it is why the system carries a confidence tier below verified. See how this check works.
