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
HPE and NVIDIA AI supercomputer switched on in May 2022 at HPE's Centre of Excellence in Grenoble: a cluster of 20 HPE Apollo 6500 Gen10 Plus systems with AMD EPYC 7763 processors and 160 NVIDIA A100 GPUs on NVIDIA Quantum InfiniBand HDR, offered to scientists and industry for AI training and simulation. It ranked tenth on the November 2022 Green500 at 38.555 GFlops/Watt (2.32 PFlop/s Rmax on 60.2 kW; TOP500 rank 331). A later re-run lifted Rmax to 2.54 PFlop/s on 59.63 kW; last TOP500 appearance was June 2025.

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.
