Practical Mechanisms for Managing Parallel and Interactive Jobs on Grid Environments

The CrossBroker is a Grid Resource Management System that provides transparent and reliable support for the execution of parallel and interactive applications on a Grid environment. In this chapter, we outline the architecture of our system and describe the key mechanisms responsible for an efficient and reliable execution of parallel and interactive applications. We also present the job description language that allows the user to take profit from our system. The extensible and orthogonal mechanisms proposed give support for co-allocation of resources for various MPI implementations and the use of several tools and services for interaction with the application while running in a remote system.
