Raven-GPU

Also known as Raven

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: 8.62 PFlop/s
Rpeak: 16.03 PFlop/s
Rmax ÷ Rpeak: 53.8%
Cores: 96,768
Power: 377 kW
Per watt: 22.9 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

The GPU partition of Raven, the Max Planck Computing and Data Facility's flagship system at Garching, serving the Max Planck Society's roughly 80 research institutes. A Lenovo ThinkSystem SD650-N V2 cluster of Intel Xeon Platinum 8360Y hosts each paired with four NVIDIA A100 40GB SXM GPUs over NVLink, connected by 200 Gbit/s Mellanox HDR InfiniBand. TOP500 lists Rmax 8.62 PFlop/s, matching MPCDF's own published 8.6 PFlop/s figure, so the tier is verified. First appeared on the June 2021 TOP500 list at rank 47. A separate CPU-only partition, sharing the Raven name but a distinct TOP500 entry (1,592 Xeon Ice Lake-SP nodes, no GPUs), is not recorded as its own row here.

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.
