JupyterLab is now the recommended user interface to use on JupyterHub Web servers. From a JupyterLab portal, you can manage your remote files and folders, and you can launch Jupyter applications like a Terminal, (Python 3) Notebooks, RStudio and a Linux Desktop.

The section JupyterHub#Compute_Canada_initiatives contains the list of available JupyterHub servers at Compute Canada. Compute Canada credentials are used for authentication.

Launching a JupyterLab portal as a job

JupyterHub Server Options form

On Béluga and Hélios, once the authentication is done on JupyterHub, your Web browser is redirected to either a previously launched portal or a form that allows you to configure and submit a new interactive job on the cluster. In any case, the JupyterLab portal is running on dedicated compute resources.

In the Server Options form, you can:

• Select the compute account to be used (any def-*, rrg-*, rpp-* or ctb-* account you have access to)
• Set the amount of hours required for the session
• Set the number of cores on a single node
• Set the amount of memory for the entire job
• Select zero or one GPU
• Select a user Interface:
  • Jupyter Notebook (old interface)
  • JupyterLab (recommended, modern interface)
  • Terminal (for a single terminal)
