The goal of the BROCCOLI ARC project is to design a platform for describing, deploying, executing, observing, administrating, and reconfiguring large-scale component-based software architectures, in particular for building discrete event simulation applications. Both the platform and the applications considered are based on software components and architecture description languages, and in particular on the Fractal component model. Therefore, the main issue addressed in this project is the scalability of such component-based architectures based on Fractal. Indeed, by allowing Fractal to scale-up to millions of components running on thousand of nodes, our aim is to establish the foundations of a massively distributed component-based simulator based on Fractal. However, the Broccoli road is paved of ambushes: existing ADLs are insufficient to describe very large architectures, the numerous data-flows and statistics generated by observations need smart context management policies, and distributed simulation is a long studied but still challenging problem, especially when combined with AOP techniques and Fractal special features such as shared components.
