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

PSC's first Bridges system, the predecessor to Bridges-2 (also in this dataset), which replaced it in early 2021. An NSF-funded HP (then, on delivery, HPE) system built around 752 Regular Shared Memory nodes of two Xeon E5-2695 v3 CPUs each, plus GPU nodes carrying NVIDIA K80, P100 and V100 accelerators, over Intel's first production Omni-Path fabric deployment. Aimed like its successor at data-intensive and non-traditional HPC users rather than a Linpack score, it was never submitted to TOP500, so no rank, Rmax, Rpeak, core count or power figure is recorded. The $9.65 million NSF award (number 1445606, to Carnegie Mellon University, PI Shawn Brown) funded an October 2015 acquisition targeting January 2016 production; TOP500's own news coverage describes it booting up and entering production around mid-2016, so only the year is recorded here. Wikipedia states 27,400 total cores across its five node types; that figure is single-sourced and is given in prose only rather than in the structured core-count field.

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.
