QosCosGrid e-Science Infrastructure for Large-Scale Complex System Simulations

This chapter focuses on two enhanced and widely used parallel computing environments: QosCosGrid-ProActive (QCG-ProActive) and QosCosGrid-OpenMPI (QCG-OMPI). QCG-OMPI is designed to enable parallel applications to run across geographically widely distributed computational resources owned and secured by different administrative organizations. QCG-ProActive was successfully integrated with the Repast Suite, a very popular Java-based, agent-based modeling and simulation platform. The chapter presents a short overview of validation scenarios. It discusses the main requirements of complex systems and other demanding parallel applications and classifies these into ?> templates.?> The chapter introduces the QCG middleware services and their key capabilities relevant to end users. A number of useful libraries and frameworks for application developers and resource providers using QCG are described. The chapter provides additional Web-based monitoring and troubleshooting tools for QCG, which are already available on some production-level computational clusters and supercomputers.
