Description
|
WINGS is a workflow system that assists scientists with the design of computational experiments. WINGS reasons about dataset and component constraints to create and validate workflows and to generate metadata for new data products. WINGS uses Pegasus as the execution engine for large-scale distributed workflow execution.

Research
|
At the core of the WINGS architecture is a workflow generation and validation algorithm that propagates component and dataset constraints throughout the structure of the workflow. This algorithm and its underlying reasoning are at the core of our research.
