Abstract:
Emerging urgent computing tools can quickly allocate computational resources for the execution of time critical jobs. Grid applications and workflows often use Grid services and service-oriented architectures. Currently, urgent computing tools cannot allocate or manage Grid services. In this paper, we evaluate a service-oriented approach to Grid service access and provisioning for urgent computing environments. Our approach allows resource providers to define urgent computing resources and Grid services at a much finer granularity than previously possible. It accommodates new urgent computing resource types, requires minimum reconfiguration of existing services, and provides adaptive Grid service management tools. We evaluate our service-oriented, urgent computing approach by applying our tools to Grid services commonly used in urgent computing work-flows and evaluate management policies through our urgent service simulator.
