Pegasus Workflow Management System

This tutorial will examine the opportunities and challenges of designing and executing scientific workflows in distributed environments. Attendees will receive an introduction to scientific workflows, their usefulness in data analysis, and the challenges of running scientific workflows in a variety of execution environments. This tutorial will outline issues that need to be addressed by any workflow system in order to be able to run scientific workflows on the grid. The program will also focus on issues of workflow composition--how to design workflow components that are portable across many platforms and how to define workflows at an appropriate level of abstraction.
