Introduction

In order to connect to one of the HPC clusters operated and maintained by ID SIS HPC, users need a valid NETHZ account. The clusters are open to all members of ETH and can even be used by external users that have a collaboration with a research group/institute at ETH Zurich.

ETH members

Members of ETH have immediate access to the clusters and can login with their NETHZ credentials.

External collaborators

Members of other institutes who have a collaboration with a research group at ETH may use the HPC clusters for the purpose of said collaboration. Their counterpart ("sponsor") at ETH must ask the local IT support group (ISG) of the corresponding department to create a NETHZ guest account for them, including e-mail address and VPN service.

First login

On the first login, users need to accept the cluster's usage rules. Afterwards their account is created automatically. A user account on a HPC cluster includes a home directory.

SSH

Linux, Mac OS X

Windows

X11

Windows

VPN
