## Revision as of 17:13, 9 October 2016

## 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 has been regularly expanded since its conception in 2013. The first phase — Euler I — was purchased at the end of 2013 and is in operation since the beginning of 2014. The second phase — Euler II — was purchased at the end of 2014 and is in operation since the beginning of 2015, with additional compute nodes added at the end of 2015. The third phase — Euler III — has just been ordered and is expected to be operational at the beginning of 2017.

## Specifiations

### Euler I

Euler I contains **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 have 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).

### Euler II

Euler II contains **768** compute nodes of a newer generation — BL460c Gen9 —, each equipped with two 12-core Intel Xeon E5-2680v3 processors (2.5-3.3 GHz). All nodes have DDR4 memory clocked at 2133 MHz (32 × 512 GB; 32 × 256 GB; 32 × 128 GB; 672 × 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).

### Euler III

Euler III will consist of **1215** compute nodes — Hewlett-Packard m710x — each equipped with a quad-core Intel Xeon E3-1285Lv5 processor (3.0-3.7 GHz), 32 GB of DDR4 memory clocked at 2133 MHz and a 256 GB NVMe flash drive. All these nodes are connected to the rest of the cluster via 10G/40G Ethernet.
