Open OnDemand

Open OnDemand is a web-based interface to computer clusters. It provides a low-threshold way to do easy work and shell access to do more. It complements, not replaces, the traditional ssh access: just like with Jupyter, it may help you get started, but most people will eventually move towards shell access (even if that shell is via Open OnDemand).

Connecting

Address: http://ondemand.triton.aalto.fi . Log in with the usual Aalto login. A pre-existing Triton account is needed.

How to use

The first view is a dashboard that provides an interface to a number of applications:

  • Shell: Top bar → Clusters → Triton shell access. Or via the file manager.

  • Files: Top bar → Files → choose your directory. You can upload and download files this way.

  • Jupyter: Top bar → Interactive apps → Jupyter

  • Other applications via the main page or Top bar → Interactive Apps → (choose).

Applications

Once logged in, there are ways to start separate applications, for example Jupyter. These run as separate, independent processes.

We have these applications available and supported:

  • Triton shell access (Shell access, just like SSH)

  • Triton desktop (run any graphical application)

  • Jupyter

  • RStudio

  • Matlab

  • VS Code Server (coming…)

Choose partition ‘interactive’ (if it asks you) and a correct account.
