Introduction

JupyterLab is now the recommended general-purpose user interface to use on a JupyterHub. From a JupyterLab server, 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 Jupyter Hubs at Compute Canada. Compute Canada credentials are used for authentication.

Launching a JupyterLab server 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 Jupyter server or a form that allows you to configure and submit a new interactive session on the cluster. In any case, the JupyterLab server 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 CPU cores that will be reserved on a single node
• Set the amount of memory for the entire session
• Select zero or one GPU
• Select a User Interface - this is where JupyterLab should be selected
