About Workspaces

A workspace is a cloud-based compute cluster built on Hadoop/AWS EMR that you can interact with directly in your browser. Once registered for the AHA Precision Medicine Platform, you can provision a workspace from the My Workspace page. It will take approximately 1 hour before the My Workspace page will display a button that you can click to log into your workspace.

The AHA Precision Medicine Platform provides a friendly web UI that allows you to write code in various languages (for example, Python, R, Scala), execute the code, and view the results as they are processed.

The AHA Precision Medicine Platform UI is based around the concept of notebook files, where each notebook contains one or more code blocks (called cells). All of the content you write in your notebook is saved, even if you pause your workspace and come back to it later.

We have included Spark libraries for various languages (e.g. Pyspark, if you're writing Python code) to leverage the full parallel computing power of the Hadoop/AWS EMR platform. You can find examples and code snippets in the sample notebooks that are included on each workspace you provision.

Web Applications:
