Abstract
This paper describes the Pegasus framework that can be used to map
complex scientific workflows onto distributed resources. Pegasus enables
users to represent the workflows at an abstract level without needing to
worry about the particulars of the target execution systems. The paper
describes general issues in mapping applications and the functionality of
Pegasus. We present the results of improving application performance
through workflow restructuring.
