Flow-based Multistage Co-allocation Service

The concept of co-allocation provides a simple mechanism to request and bind resources in a coordinated fashion in Grids across virtual organization boundaries. We have designed an advanced multistage co-allocation strategy based on resource hierarchies defined through user-specific patterns. The model manages simple flows between resources to perform managed job executions. We demonstrate the usefulness of our model on several examples and discuss advantages and disadvantages of the model
