In this paper a model for scheduling in wide-area systems is described. The model is federated and utilizes a collection of local site schedulers that control the use of their res...
: Systems are defined by their components and the relationships among their components, hence when modelling systems using an objectoriented (OO) approach, objects alone are insuff...
We describe an algebra for composing automata in which the actions have probabilities. We illustrate by showing how to calculate the probability of reaching deadlock in k steps in...

The ODP computational viewpoint describes the functionality of a system and its environment, in terms of a configuration of objects which interact at interfaces. Computational obj...
In this paper, we describe the design and implementation of two mechanisms for fault-tolerance and recovery for complex scientific workflows on computational grids. We present our ...
