Abstract: We have described the problem of compositional hierarchical scheduling frameworks upon heterogeneous multiprocessor platforms. For this, we suggest extending virtual cluster-based scheduling to clusters comprising heterogeneous processors, and we introuce the hierarchical multiprocessor periodic resource (HMPR) model. Our starting point is that some results on component abstraction obtained for the multiprocessor periodic resource (MPR) model by Shin et al. (2008) apply with due adaptation, with new results being needed to complete and tighten the component abstraction, solve the interface composition problem, and answer other open questions.
