## Availability
## Who can access the university JupyterHub?
The Jupyterhub is available for every member of the university, including employees and students. The resource quotas depend on the respective user's status and user groups. Higher resource quotas up to 16 vCPUs and 64GB of RAM and additional GPUs can be requested via email at [jupyterhub@uni-muenster.de](mailto:jupyterhub@uni-muenster.de).

- eScience: Mainly for natural science and data analysis
- Development: Mainly for programming, e.g. C++, Rust
## Session duration
## How long can I run sessions?
To fairly distribute resources, we will end idle session after 60 minutes of inactivity for students and 240 minutes for employees. Additionally, we might also stop non-idle sessions, if they run for more than 24h, e.g., in case of security relevant updates to the cluster. Jupyterhub is designed for interactive session. If you require longer running non-interactive jobs or more compute power, the HPC cluster will be a better option (more information at their website.)

## Where is my data saved?
## Accessing your home directory from outside the hub
Your default working directory `~` is set to your personal home folder, ensuring consistency across your sessions. This folder provides 10 GB of personal storage. If additional storage is required, you have the option to utilize Sciebo or a project cloud share
## How can I acess my home directory from outside the hub?
Your personal home folder ~ is also available under `\\wwu.de\ddfs\Cloud\wwu1\u_jupyterhub\home` within the university network. It can be accessed via the file explorer in Windows. For unix/linux systems, we recommend mounting it via the terminal using the following command:

Mounting via the file manager GUI in Ubuntu (or other GNOME based systems) can result in reduced performance due to the use of gvfs.
## Cloud shares in JupyterHub
## How can I use (project) cloud shares in JupyterHub?
Cloud storage is mounted on your Jupyter server at `/cloud/wwu1`. You can create a symlink to your project folder in your home directory by executing `ln -s /cloud/wwu1/my_cloud_folder ~ ` . This allows you to use the file browser on the left hand side to access the data.
