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 — was delivered by the end of 2016 and is in operation since the beginning of 2017.
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)
- Between 64 and 256 GB of DDR3 memory clocked at 1866 MHz (64 × 256 GB; 32 × 128 GB; 352 × 64 GB).
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)
- Between 64 and 512 GB of DDR4 memory clocked at 2133 MHz (32 × 512 GB; 32 × 256 GB; 32 × 128 GB; 672 × 64 GB).
Euler II also contains 4 very large memory nodes — Hewlett-Packard DL580 Gen9 —, each equipped with:
- Four 16-core Intel Xeon E7-8867v3 processors (2.5 GHz)
- 3072 GB of DDR4 memory clocked at 2133 MHz.
Euler III contains 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
- A 256 GB NVMe flash drive
All these nodes are connected to the rest of the cluster via 10G/40G Ethernet.
Euler IV will be installed at the end of 2017. It will contain 288 high-performance nodes — Hewlett-Packard XL230k Gen10 —, each equipped with:
- Two 18-core Intel Xeon Gold 6150 processors (2.7-3.7 GHz)
- 192 GB of DDR4 memory clocked at 2666 MHz.
All these nodes will be connected together via a new 100Gb/s InfiniBand EDR network.
Euler contains two storage system:
- An enterprise-class NAS system (NetApp FAS3250 and FAS8080EX) for long-term storage, such as home directories, applications, virtual machines, project data, etc.
- A high-performance parallel file system (Panasas PAS14) for short- and medium-term storage, such as scratch and work file systems
Euler contains two types of networks:
- A common 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)
