SuperMUC-NG

Operated by LRZ at Leibniz Supercomputing Centre, Garching .

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: 32 of 52 systems have a readable citation that names them, and 4 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

One of the largest Lenovo-integrated systems anywhere, and a reminder that Lenovo's position in this market came from a single 2014 transaction: IBM's x86 server business. Warm-water cooled with heat recovery, on Intel Omni-Path - a fabric its own vendor discontinued the year after this machine entered service.

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.

None of the cited sources could be read from our network: the hosts returned bot challenges or did not respond. This check says nothing about the citations either way. See how this check works.
