Klone (UW)

Also known as Hyak Klone

Operated by University of Washington .

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

The University of Washington's third-generation Hyak HPC cluster, in service since January 2021. The system architecture page states 44,184 CPU cores (AMD Genoa, Intel Cascade Lake, Intel Ice Lake), 954 GPU cards (Turing, Ampere, Hopper generations), HDR100 InfiniBand in a 3:1 blocking two-layer fat tree and 2.7 PB of GPFS; the GPU page lists L40, L40S, A40, 2080 Ti, Titan, RTX6000, A100 and P100 cards. No FLOPS figure is published.

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.
