For this we propose the uniform multiprocessor periodic resource (UMPR) model for a component interface. We extend previous work by fellow researchers (for dedicated uniform multiprocessors, and for compositional HSFs on identical multiprocessors), by providing mechanisms for the multiple aspects of compositional analysis: a sufficient test for local schedulability of sporadic task sets under global Earliest Deadline First (GEDF) and guidelines for the complex problem of selecting the virtual platform when abstracting a component. Finally, we present experimental results that provide evidence for the need of future developments within the realm of compositional HSFs on uniform multiprocessors.
