Actor-Oriented Design of Scientific Workflows [chapter]

Shawn Bowers, Bertram Ludäscher
2005 Lecture Notes in Computer Science  
We first develop a formal model for scientific workflows based on an actor-oriented modeling and design approach, originally developed for studying models of complex concurrent systems.  ...  Scientific workflows are becoming increasingly important as a unifying mechanism for interlinking scientific data management, analysis, simulation, and visualization tasks.  ...  Events are processed in global time order, and in response to an event an actor is permitted to emit events at the present or in the future, but not in the past.  ...
