EAGLE pi

EAGLE is the visual editor for building DALiuGE workflows. This guide helps you go from first launch to your first runnable graph.

An example of components in EAGLE

EAGLE is the UI for the DALiuGE workflow framework. You design workflows as connected components, tune parameters, translate to a deployable graph, and then execute.

How EAGLE Works

  1. Build a workflow from Components.

  2. Organize components through Palettes.

  3. Create a Logical Graph Template in the editor.

  4. Set values in a Graph Configuration to produce a Logical Graph.

  5. Translate it into a Physical Graph Template.

  6. Deploy and execute as a Physical Graph.

A component can wrap many payload types, such as shell commands, Python code, C/C++, MPI apps, or data handlers. Components are defined in JSON descriptions so EAGLE can display, validate, and connect them.
