Embedding Software Requirements in Grid Scheduling

Executive Summary

Both grid and cloud applications may require specific software for their execution. Introducing such requirements into the DAG describing the dependencies among the tasks of an application leads to a combinatorial problem with numerous possibilities of modified DAGs. This paper introduces an algorithm to obtain a single DAG with the minimum possible makespan by reducing the need for data transfer over the network. Grid networks (Grids) have been designed to provide computational resources on a large scale for advanced science and engineering. In grids, computational resources spread around the world are connected by network links composing virtual organizations for the execution of highly demanding applications.
