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.

In Compute Canada context, JupyterHub removes the requirements for users to install their own version of Jupyter Notebook and for users to create an SSH tunnel with the server to proxy the web connection. JupyterHub handles these two requirements allowing the users to connect to Jupyter Notebook using only a recent web browser.

Initiatives in Compute Canada

There are a few regional initiatives in Compute Canada to offer access to computing ressources through JupyterHub.

• The Pacific Institute for the Mathematical Science 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 institution credentials. The hubs are hosted on Compute Canada Cloud and are essentially thoughts for educational purposes and courses. Institutions interested in getting their own hub can visit http://syzygy.ca.
• Calcul Québec hosts a hub https://jupyter.calculquebec.ca that provides access to notebook servers spawn through jobs on two of Université Laval's HPC systems : Colosse and Helios. To authenticate on this hub, users are required to have an account at Calcul Québec and on either one of the two former systems. To know more, visit Calcul Québec wiki JupyterHub page.
• SciNet hosts a hub available through an SSH tunnel via login.scinet.utoronto.ca. To know more, visit SciNet wiki JupyterHub page.
