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 “Euler” cluster consists of 76 HPE c7000 blade chassis each equipped with 16 HPE. ProLiant BL460 c Gen8/9 blades and of 27 HPE Moonshot 1500 each equipped with 45 m710x cartridges and 3 fat nodes with 3TB memory each. In total Euler contains 1'216 compute nodes with 2 Intel E5-26XX v2/v3 12 core processors (29'184 cores) and about 80 TB of RAM and 1'215 compute nodes with one Intel E3-1585Lv5 4 core processors (4'860 cores) and 39 TB of RAM.

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)


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