Using Jupyter Hub on Talon

text

What is JupyterHub?

Jupyter Hub brings the power of notebooks in your browser. It gives users access to computational environments and resources without burdening the users with installation and maintenance tasks. Users - including students, researchers, and data scientists - can get their work done in their own workspaces on shared resources which is managed efficiently by our Talon HPC team.

JupyterHub runs on Talon UNT HPC, and makes it possible to serve a pre-configured data science environment to any UNT user. It is customizable and scalable, and is suitable for small and large teams, academic courses, and large-scale infrastructure.
