Events as a Basis for Workflow Scheduling

This paper evaluates using event-based scheduling as a basis for dynamic workflow management. To do this, the WorkflowRunner is introduced as a tool for conducting event driven scheduling in a robust manner. It is evaluated in comparison to Slurm and the WorkflowRunner is found to schedule analysis ~2.5x quicker, in the majority of use cases. An example workflow is also presented, demonstrating how this style of scheduling allows for complete modification of the workflow structure at runtime, something very difficult to achieve in traditional workflow management systems. These developments are expected to be of particular use to dynamic scheduling systems, as well as for distributed, or heterogeneous systems such as those looking to accommodate human-in-the-loop interactions.
