'''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.

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 is in operation from 2015 to 2020. Euler III was purchased at the end of 2016 and is in operation since the beginning of 2017. Euler IV was purchased at the end of 2017 and is in operation since the beginning of 2018. Euler V, which replaced Euler I, was purchased in the fall of 2018 and is in operation since the end of 2018. 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.

Revision as of 14:13, 8 August 2022

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 is in operation from 2015 to 2020. Euler III was purchased at the end of 2016 and is in operation since the beginning of 2017. Euler IV was purchased at the end of 2017 and is in operation since the beginning of 2018. Euler V, which replaced Euler I, was purchased in the fall of 2018 and is in operation since the end of 2018. 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.
