Operated by Navy DSRC at Navy DSRC (Stennis Space 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: 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.

Measured performance

Rmax: 1.29 PFlop/s
Rpeak: 2.05 PFlop/s
Rmax ÷ Rpeak: 62.7%
Cores: 61,256
Power: 2.32 MW
Per watt: 0.6 GF/W

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 XC40 at the Navy DoD Supercomputing Resource Center, Stennis Space Center, Mississippi: TOP500 lists Intel Xeon E5-2698v3 16-core 2.3 GHz processors with Intel Xeon Phi 5120D coprocessors over Aries, 61,256 cores, Rmax 1.286 PFlop/s, Rpeak 2.050 PFlop/s and 2,324 kW, installed 2015, first listed at rank 45 on the June 2015 list and last on the June 2020 list. Defense One reported in December 2014 that the HPCMP had contracted Cray for two XC40 systems and two Sonexion storage systems for the Navy center, to be installed in 2015 and to raise the center capacity two and a half times for coastal-ocean circulation and wave-model oceanography. It is one of the two identical XC40 listings (with Gordon, TOP500 system 178521); a third smaller XC40 named Bean is not recorded here. Not the same machine as the Conrad at Shared Services Canada. Tier reported: the contract article does not name the machines.

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.
