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.

Measured performance

Rmax: 192.10 TFlop/s
Rpeak: 226.56 TFlop/s
Rmax ÷ Rpeak: 84.8%
Cores: 9,440
Power: -
Per watt: - 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

Pawsey's dedicated real-time computer for Australia's two Square Kilometre Array precursors, ASKAP and the Murchison Widefield Array, installed in June 2013 as the first phase of a Cray Cascade-family contract that added Magnus, already in this dataset, the following year. ICRAR's own announcement of the AU$33 million SuperScience-funded procurement names Cray as the vendor and iVEC, Pawsey's predecessor organisation, and CSIRO as the managing bodies, though it does not give Galaxy's own hardware figures; those come from TOP500 alone, 209th on the November 2013 list. No decommissioning notice was found, so status is carried as last documented rather than inferred. TOP500 is the only source for Rmax, Rpeak and core count, so the tier is reported.

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
icrar.org	does not name this system	-
top500.org	names system and part	Intel Xeon E5-2690 v2, Cray Aries, Cray Linux Environment
