The growing need for continuous processing capabilities has led to the development of multicore systems with a complex cache hierarchy. Such multicore systems are generally designed for improving the performance in average case, while hard real-time systems must consider worst-case scenarios. An open challenge is therefore to efficiently schedule hard real-time tasks on a multicore architecture. In this work, we propose a mathematical formulation for computing a static scheduling that minimize L1 data cache misses between hard real-time tasks on a multicore architecture using communication affinities.
