This page describes the hardware of the different generations (I-VII) of Euler. For information on how to use the cluster, please check the tutorials page.

Introduction

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.

Euler II (left) and Euler I (right)
Euler VII

Euler has been regularly expanded since its conception in 2013. The first phase — Euler I — was purchased at the end of 2013 and was in operation from 2014 to 2018. The second phase — Euler II — was purchased at the end of 2014 and was in operation from 2015 tol 2020. Euler III was purchased at the end of 2016 and was in operation from 2017 to 2022. Euler IV was purchased at the end of 2017 and was in operation from 2018 to 2022. Euler V, which replaced Euler I, was purchased in the fall of 2018 and was in operation until July 2023. Euler VI was purchased at the end of 2019 and is in operation since the beginning of 2020. Euler VII has been purchased in two phases, the first one is operational since January 2021 and the second one since January 2022. Euler VIII was installed at the end of 2022 and has been in operation since the beginning of 2023. Euler IX was purchased at the end of 2023 and will be operational in January 2024.

GPU nodes

Euler contains dozens of GPU nodes equipped with different types of GPUs:

GPU nodes are not linked to a specific Euler expansion cycle but are purchased according to shareholders' needs. Their specifications (CPU, RAM, disk, networks) vary considerably, even between nodes equipped with similar GPUs.

Storage

Euler contains two types of storage system:

  • An enterprise-class NAS system (NetApp FAS 9000 & AFF A800) for long-term storage, such as home directories, applications, virtual machines, project data, etc.
  • A high-performance Lustre parallel file system (DDN ES14KX) for short- and medium-term storage, such as scratch and work file systems

Home directories and other critical data are backed up daily; all other data (except scratch) are backed up at least once per week for disaster recovery.

Networks

Euler contains multiple networks:

  • A common 100/25/10 Gb/s Ethernet network for data transfer between the storage systems and the cluster's compute and login nodes
  • Three separate 56 Gb/s InfiniBand FDR networks for data transfer between the compute nodes themselves (e.g. MPI)
  • A 100 Gb/s InfiniBand EDR network for data transfer within Euler IV (MPI) and between Euler IV and the new Lustre high-performance storage system
  • A 200/100 Gb/s InfiniBand HDR network for data transfer within Euler VI–VII with 100 Gb/s from compute nodes to switches and multiple 200 Gb/s links between switches
