Increasing demand for performance and efficiency has driven the computer industry toward multicore systems. These systems have become the industry standard in almost all segments of the computer market from high-end servers to handheld devices. In order to efficiently use these systems, an extensive amount of research and industry support has been devoted to developing explicitly parallel programming paradigms, such as streaming models, and new compiler techniques. One important challenge that arises in multicore systems is the ability to dynamically adapt a running application to a target architecture in the face of changes in resource availability (e.g., number of cores, available memory or bandwidth).
