The initial view of a JupyterLab Profile does not show any customizable settings. The JupyterLab is configured by default to use pre-defined settings suitable for the Profile.

Clicking  Default Settings shows the partition,  runtime duration and number of cores used as defaults.

Clicking  Advanced Settings shows even more customization options that will be used for the JupyterLab Slurm job.

For more information on what each setting does, we recommend reading the Slurm documentation for more details.
