Once you gain access, you can login to the frontend nodes
gwdu103.gwdg.de. These nodes are accessible via ssh from the GÖNET. If you come from the internet, the preferred way to gain access to the GÖNET is to use a VPN connection. Alternatively you can first login to
login.gwdg.de. From there you can then reach the frontends.
ssh <GWDG username>@login.gwdg.de
The frontends are meant for editing, compiling, and interacting with the batch system, but please don't use them for testing for more than a few minutes, since all users share resources on the frontends and will be impaired in their daily work, if you overuse them. gwdu101 is an AMD based system, while gwdu102 and gwdu103 are Intel based. If your software takes advantage of special CPU dependent features, it is recommended to use the same CPU architecture for compiling as targeted for running your jobs.
