SWBES08: Challenging Issues in Workflow Applications

A Tale of Two Workflows

Presenters and Authors
  • Roger Barga

Scientific workflows have become an archetype to model and run in silico experiments by scientists. These workflows primarily engage in computation and data transformation tasks to perform scientific analysis. There is, however, a whole class of workflows that are used to manage the scientific data when they arrive from external sensors and are prepared for becoming science ready and available for use. While not directly part of the scientific analysis, these workflows operating behind the scene on behalf of the “data valets” play an important role in end-to-end management of scientific data products. They share several traits with traditional scientific workflows: both are data intensive and use web resources. However, they also differ in significant respects, for example, in the degree of reliability required and the type of provenance collected. In this talk I will compare and contrast these two classes of workflows – Science Application workflows and Data Preparation workflows – and use these to drive observations, along with shared and unique requirements from workflow systems for eScience in the Cloud.
