Tachyon
Also known as KISTI Tachyon; Sun Blade 6000 cluster
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.
| Role | Part | Supplier at build | Quantity | Confidence | Source |

The read
KISTI's 2008 Sun Blade 6000 cluster, the Opteron machine that preceded Tachyon II (already in this dataset). TOP500 lists 3,072 cores of quad-core 2 GHz AMD Opteron on 4x DDR InfiniBand under Linux, 16.99 TFlop/s Rmax, 24.58 TFlop/s Rpeak and 129 kW, ranked 131st in June 2008 and 278th in November 2008 (https://www.top500.org/system/175566/). TOP500's KISTI site page lists it among the centre's twelve documented systems. TOP500 is the only source of the figures, so the tier is reported; status is held as of the last list.

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 | Mellanox InfiniBand DDR |
