Abstract

We propose in this paper Actor Petri net Model for designing scientific workflow applications that are characterized by heterogeneous data and intensive computing. Based on many other workflow representation models (such as Actor Network, a series of Petri nets, and DFL), it is intended to be a runtime model that can represent dynamic scenarios of applications. Scientific workflow applications designed and run upon this model can offer very flexible operations to control their running states, including data operations, skeleton operations, serialization and deserialization, and VCR control. The intrinsic properties of the model are that designed workflows can process complex data and run on distributed environments, so it can be used to design any open world applications with almost no restrictions, including as a basic design and execution infrastructure for DDDAS and the coming Cloud Computing.
