Interactive Applications in OnDemand#

Accessing Interactive Applications#

To start using interactive applications:

  1. Connect to OnDemand at https://ondemand.hpc.iter.es/ with your credentials.
  2. Navigate to the "Interactive Apps" tab on the main navigation bar.
  3. Here you will find a list of available applications. Select the desired application: Code Server, JupyterLab, or RStudio, and choose between the CPU or GPU version according to your needs.

Available Applications#

Code Server#

Code Server provides a version of Visual Studio Code that runs on the server and is accessible through the browser. It is ideal for software development and code editing.

  • For CPU/GPU: Select the version you need according to the type of processing required for your project.
  • Configuration: Specify the necessary resources (such as number of cores, memory, and runtime). For the GPU version, make sure to also select the desired type of GPU.
  • Usage: Once launched, the application will open Visual Studio Code in your browser, allowing you to work with your files and projects stored on the server.

The application will ask for a password to access:

JupyterLab#

JupyterLab offers an interactive data science environment that supports programming languages such as Python, R, and Julia.

  • For CPU/GPU: Choose according to the computational demands of your Jupyter notebooks.
  • Configuration: Indicate the necessary computational resources. For the GPU version, select the type of GPU you prefer.
  • Usage: When launching JupyterLab, a new window will open in your browser to work with notebooks, code, and data.

Once inside you will see the following:

RStudio#

RStudio provides an integrated development environment for R, facilitating programming, data visualization, and more.

  • For CPU/GPU: Depending on the processing needed for your data analysis, choose the appropriate version.
  • Configuration: Allocate the resources you require, including the type of GPU if you opt for that version.
  • Usage: RStudio will open in the browser, providing access to the R development tools in a familiar environment.

Once inside you will see the following:

General Tips#

  • Save Your Work: Make sure to regularly save your files and projects to avoid losing progress.
  • Manage Your Resources: Close the interactive applications when you are not using them to free up resources on the cluster.
  • Consult the Documentation: Each application has specific features and configurations. Consult the official documentation to make the most of them.
