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.
These workflows come from a paper by Bharathi, et al. . There is another paper with more information about the workflows by Juve, et al. .
The code used to generate these workflows is available here. The code generator sometimes generates negative task runtimes, so watch out for that.
A large collection of DAXes similar to the ones listed below is available here. Note that it is about 375 MB.
LIGO Inspiral Analysis
These workflows come from a report by Ramakrishnan and Gannon .
The Python code used to generate the DAX files below, as well as several others, can be downloaded here.
