NCEP Gyre
Also known as Gyre
Operated by NOAA .
Researched with AI assistance, checked by scripts. These rows were researched by AI agents reading public operator, laboratory and vendor sources, appended by scripts and checked by automated validation; no subject-matter expert has reviewed them (how this site is made). A mechanical second-reader pass has since fetched every cited source: 1350 of 1540 systems have a readable citation that names them, and 64 are genuinely weakly sourced. Every claim carries its source and a confidence tier. Treat anything below verified as a lead, not a citation.

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
The Orlando backup-center twin of Tide (ncep-tide) in NOAA's first-phase operational weather computing: an IBM iDataPlex DX360M4 cluster on 56 Gb/s FDR InfiniBand running Red Hat Enterprise Linux with IBM LSF, per Next Platform. TOP500 gives Gyre exactly the same figures as Tide (37,312 cores, 705.9 TFlop/s Rmax, 776.09 TFlop/s Rpeak, 775.04 kW) and lists it one rank below Tide on every list from June 2015 (rank 104) to November 2017 (rank 380). Next Platform reports the Tide and Gyre clusters processing 3.5 billion observations a day with a 99.9 percent uptime goal for running models; it also says each cluster grew to about 830 TFlop/s after IBM's January 2015 node additions, a figure TOP500 does not reflect. The Cray XC40 and Dell systems NOAA added later are recorded as noaa-luna, noaa-surge, noaa-mars and noaa-venus. Tier is reported because TOP500 is the only source for the benchmark figures.

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 |
|---|---|---|
| nextplatform.com | names system and part | Intel Xeon E5-2670, Mellanox InfiniBand FDR |
