Adapting Grid Services for Urgent Computing Environments

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 workflows and evaluate management policies through our urgent service simulator.
