JupyterHub

Introduction

"JupyterHub, a multi-user Hub, spawns, manages, and proxies multiple instances of the single-user Jupyter notebook server. JupyterHub can be used to serve notebooks to a class of students, a corporate data science group, or a scientific research group."

JupyterHub eliminates the requirement for users to install their own version of Jupyter Notebook; they can connect to the application using only a recent web browser.

User Interface

While JupyterHub allows each user to use one Jupyter server at a time, there may be multiple user interfaces available:

• Jupyter Notebook (classic interface)
• JupyterLab (recommended, modern interface)
• Terminal (for a single terminal only)

Otherwise, JupyterHub could have been configured to force a specific user interface.

Compute Canada initiatives

Some regional initiatives offer access to computing resources through JupyterHub.

• The Pacific Institute for the Mathematical Sciences in collaboration with Compute Canada and Cybera offer cloud-based hubs to universities and schools. Each institution can have its own hub where users authenticate with their credentials from that institution. The hubs are hosted on the Compute Canada Cloud and are essentially for training purposes. Institutions interested in obtaining their own hub can visit http://syzygy.ca. See Compute Canada and PIMS launch Jupyter service for researchers.

• The Calcul Québec hub provides access to notebook servers spawned through jobs on the GPU cluster Hélios.
• Niagara has a node which has been designated a Jupyter Hub and it can run Jupyter Notebook sessions. To learn more, see the SciNet JupyterHub wiki page.
• There is a JupyterHub at Béluga: https://jupyterhub.beluga.computecanada.ca/
