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

NCHC's CPU-only cluster of 900 nodes, each with two 28-core Xeon Platinum 8280 CPUs, on HDR100 InfiniBand, built with QCT QuantaGrid servers. It first appeared on the November 2020 TOP500 at 181st and had slid to 456th by June 2024, its last listing. NCHC and QCT give a peak of 2.7 PFlop/s where TOP500 says 4.35, so no peak is recorded and the conflict is logged. TOP500 gives the clock as 2.7 GHz and NCHC as 2.4 GHz. No official start date was found in a page we fetched, so it is blank. NCHC's current supercomputer page still lists the system, but it is undated, so the operational status is a reading of that page. TOP500 is the only source for Rmax, Rpeak and core count, so the tier is reported.

Where sources disagree

We record conflicts instead of picking a winner quietly. All open questions.

Peak performance: 4.35 PFlop/s (TOP500 Rpeak) against 2.7 PFlop/s (NCHC). QCT also gives 2.7. No peak is recorded.

2026-09-20 Added with a rank pointer; its peak is disputed between TOP500 and NCHC

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
