Outline

• In this lecture, we will learn:
  • CSC resources for notebooks
  • Deploying containerised notebooks

Why use Jupyter/Rstudio?

• Easy-to-use and popular
• Visually pleasing interfaces
• Interactivity
• Hides complexity

Why use CSC services for Jupyter/RStudio?

• Free-of-charge (for Finnish higher education and research institutes)
• Resource availability and their scalability
• Easy-to-use services
• Customization possibilities
• Reproducibility of environment
• Same environment for all students
• CSC specialist support

CSC’s options for notebooks

• HPC web interfaces: Puhti |Mahti|LUMI
• CSC Noppe (previously CSC Notebooks)
• Rahti Container Cloud

Puhti web interface

Puhti web interface: Access some of applications on Puhti via browser

CSC Noppe

CSC noppe: Easy-to-use applications for courses/collaborations

Rahti container cloud

Rahti container cloud: Containers-as-a-service platform at CSC

Port mapping in docker containers

• Containers communicate each other in the same network
• Port mapping enables a process inside the container to outside world
• Port mapping is not mandatory for all containers
• Syntax: docker run -p <hostport:containerport> imagename:tag

Deploying notebooks on Puhti web interface

• Understand how notebooks are run on Puhti
• Web interface eases the process of deployment for users
• Notebooks are not for heavy jobs
  

Deploying Jupyter notebooks on Puhti web interface

• Existing Jupyter notebook can be easily launched from Puhti Web Interface
• Custom installation with Jupyter Notebook:
  • Use tykky container wrapper to download Docker images from a registry or use a local image and launch notebook on Puhti web interface
  • Create environment/module(s) and then launch notebook from Puhti Web interface
• As a special case “Jupyter for courses” can be used to customise for your course
  • Follow our example here

Deploying Rstudio on Puhti web interface

• Existing Rstudio versions on Puhti can be launched easily on Puhti Web Interface
• Custom installation with Rstudio:

  • Approach 1: Intall your own packages on /projappl directory and then launch version-specific rstudio environment from Puhti web interface

  • Approach 2: Use existing Docker images from e.g., DockerHub

    • e.g., rocker/rstudio: Base R + RStudio Server installation
    • Launch custom Rstudio with SSH tunneling (bit involved on HPC system)
