Abstract

Traditional workflow systems don't handle dynamic scenarios well, as they are centralized and pre-defined at the start of the project. In this paper, we present a P2P framework to support dynamic workflows, which uses contracts to deal with unexpected changes in the flow of activities. DynaFlow is an agent based framework, where agents take action when exceptions occur. DynaFlow could provide adequate support for E-Science experiments mapped into workflows instances, with tasks operating in distributed environments and diverse types of computational resources and data.
