SoRTGrid: A Grid Framework Compliant with Soft Real-Time Requirements

Current grid resource management tools provide sufficient support for jobs executed in batch or “best-effort” modes, but are not adequate for jobs with demanding quality of service requirements, like jobs with time constraints. For such class of applications, missing the required deadline can have unpredictable consequences, from loss of quality to inconsistent results. In this chapter we present SoRTGrid, a grid framework that provides a set of services and features to discover and manage resources for soft real-time jobs. SoRTGrid is based on a direct comparison of the application requirements with the available resource offers and relies on a distributed Bid repository coupled with an overlay grid architecture.
