We specify an abstract model for dynamic distributed control systems in which the component objects make local decisions based on system-wide constraints and approximate global state. We focus on the issue of distributed resource management, exploring a solution that is both compositional and scalable because it builds global events into the Java infrastructure by exploiting its multicast facil...

The implementation of large-scale Monte Carlo computation on the grid benefits from state-of-the-art approaches to accessing a computational grid and requires scalable parallel random number generators with good quality. The Globus software toolkit facilitates the creation and utilization of a computational grid for large distributed computational jobs. The Scalable Parallel Random Number Gener...
