1.1 AI Systems Login

There are two ways how users can access the AI Systems, either via a Terminal (SSH) or via the interactive Web Interface. More information below.

Login via Terminal (SSH)

Use SSH within your terminal to connect to login.ai.lrz.de and log in with your LRZ credentials. Ensure your device is connected to the Munich Scientific Network (MWN). The following command logs you into the AI Systems, specifically onto one of the dedicated login nodes. These nodes are intended for preparing and submitting jobs to the compute nodes. From the login nodes, you can allocate resources located on the compute nodes using the Slurm Workload Manager. The compute nodes offer direct access to powerful hardware resources, including CPUs, GPUs, and large memory capacities.

ssh login.ai.lrz.de -l your_username

Attention: Do not perform heavy computations on the login nodes!

SSH Key Setup

Generate an SSH key pair on your local machine.
Replace USER with your LRZ User ID in all commands.

ssh-keygen -t ed25519 -C "USER@ai" -f ~/.ssh/id_ed25519_lrz_ai

Copy the public key to the server:

ssh-copy-id -i ~/.ssh/id_ed25519_lrz_ai.pub USER@login.ai.lrz.de

Create a config entry in ~/.ssh/config:

Host ai
    HostName login.ai.lrz.de
    User USER
    IdentityFile ~/.ssh/id_ed25519_lrz_ai
    ForwardAgent yes

Test the connection:

ssh ai

Login via Browser

Alternatively, you can access the web-based frontend at https://login.ai.lrz.de using the same LRZ credentials. For more information, see 6. Interactive Apps.
