An Aspect-Oriented Programming Model for Bag-of-Tasks Grid Applications

This paper presents a novel programming model for explicitly separating parallelization and middleware-specific concerns in bag-of-tasks (BoT) grid applications. The model uses Java threads for application decomposition, and aspect-oriented programming to dynamically (and transparently) convert the application´s thread objects into independent grid tasks, using the services of a specific grid middleware API. This paper also describes early experimental results showing the model´s modularity gains and performance overhead, when applied to implement BoT grid applications using OurGrid.
