Euler stands for Erweiterbarer, Umweltfreundlicher, Leistungsfähiger ETH-Rechner. It is an evolution of the Brutus concept. Euler also incorporates new ideas from the Academic Compute Cloud project in 2012–2013 as well as the Calculus prototype in 2013.

The Euler cluster is not destined to replace Brutus, at least not in the near future, but to complement it. Whereas Brutus is optimized for high-throughput, Euler is designed squarely for speed.

Life time



Getting started with Euler

Compute nodes

The first phase of Euler contains a total of 448 compute nodes — Hewlett-Packard BL460c Gen8 —, each equipped with two 12-core Intel Xeon E5-2697v2 processors (2.7 GHz nominal, 3.0–3.5 GHz peak). All nodes are equipped with DDR3 memory clocked at 1866 MHz (64 × 256 GB; 32 × 128 GB; 352 × 64 GB) and are connected to two high speed networks (10 Gb/s Ethernet for file access; 56 Gb/s InfiniBand FDR for parallel computations).

Compared to Brutus, Euler offers:

  • 3x more performance per core (28 vs 8.8 GF peak)
  • 36% more performance per node (576 vs 422 GF peak)
  • 30% more computing capacity overall (260 vs 200 TF)

The second phase of Euler contains 320 compute nodes of a newer generation — BL460c Gen9 —, each equipped with two 12-core Intel Xeon E5-2680v3 processors and 64 GB of DDR4 memory. These additional nodes — in production since March 2015 — increase cluster's computing capacity to approximately 570 TF.


  • All nodes are connected to the cluster's Gigabit Ethernet backbone
  • All nodes are connected to a high-speed InfiniBand FDR network
