Apptainer container setup for GSI servers

This instruction explains how to setup a working environment for GSI servers (lustre.hpc.gsi.de nodes). The setup is involved with multiple programs, such as TMux, zsh, apptainer and ssh. A similar setup can should also be achievable using alternatives, like bash and screen.

Important

The server address lustre.hpc.gsi.de contains multiple nodes. Starting a ssh session with this address could be led to a different node, therefore, losing all tmux sessions from the last login. Users should start a ssh session with a specific node address. In the following example, dslustre01.hpc.gsi.de is used as an example.

Step 1: SSH configuration

In the local machine (either your personal computer or a terminal), you should have already created the ssh public and private key. By default, your ssh configuration folder should be ~/.ssh. Open the file config in the folder (create one if config file doesn't exist)
