NEMO bwForCluster

Also known as bwForCluster NEMO

Operated by University of Freiburg at University of Freiburg HPC site .

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: 525.71 TFlop/s
Rpeak: 532.22 TFlop/s
Rmax ÷ Rpeak: 98.8%
Cores: 15,120
Power: 257.04 kW
Per watt: 2.0 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

bwForCluster NEMO at the University of Freiburg, a DALCO H88 cluster of Xeon E5-2630v4 10C 2.2GHz nodes on Intel Omni-Path for neuroscience, particle physics, microsystems engineering and materials science. TOP500 lists 15,120 cores, 0.53 PFlop/s Rmax and 257 kW and ranks it 215th in June 2016, 296th in November 2016 and 390th in June 2017. The Freiburg HPC newsletter of December 2017 reports an inauguration in August 2016 and an October 2017 extension of 152 nodes to 900 compute nodes and 18,000 cores, so the TOP500 figures describe the earlier size.

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
top500.org	names system and part	Omni-Path Architecture
