To facilitate evaluation of workflow algorithms and systems on a range of workflow sizes, we have developed a workflow generator. This generator uses the information gathered from actual executions of scientific workflows on the Grid as well as our understanding of the processes behind these workflows to generate synthetic workflows resembling those used by real world scientific applications.

Ramakrishnan and Gannon Workflows
These workflows come from a report by Ramakrishnan and Gannon [2].
