This repository is no longer maintained. We have released a new Workflow Generator as part of the WorkflowHub Project.
This repository contains several synthetic workflow generators that can be used to evaluate scheduling and provisioning algorithms for scientific workflow management systems. These workflow generators are based on models of real applications that have been parameterized with file size and task runtime data from execution logs and publications that describe the workflows. If you use this code to generate data that is used in a publication, please cite [1]. Please also cite the relevant publication for the workflows you use.
The 'bharathi' subdirectory contains a Java workflow generator that produces synthetic workflows for the applications described in [2,3].
The 'juve' subdirectory contains a Python workflow generator that produces synthetic workflows for the applications described in [4,5,6,7].
