Workflow Generator

The second axis of the WorkflowHub project targets the generation of realistic synthetic workflow traces with a variety of characteristics. The Workflow Generator, provided as part of the WorkflowHub Python package, uses recipes of workflows for creating different synthetic workflows based on distributions of workflow job runtime, and input and output file sizes. The resulting workflows are represented in the WorkflowHub JSON format, which is already supported by simulation frameworks such as WRENCH.

The WorkflowHub Python package provides a number of workflow recipes for generating realistic synthetic workflow traces. Each recipe provides different methods for generating synthetic, yet realistic, workflow traces depending on the properties that define the structure of the actual workflow.

The current list of available workflow recipes include the following workflow applications:

The Workflow Generator is constantly evolving and additional workflow recipes will be added into new releases of the Python package.
