In this paper, we consider the communications involved by the execution of a complex application deployed on a heterogeneous platform. Such applications extensively use macro-communication schemes, for example to broadcast data items to several targets, known as the multicast operation. Rather than seeking to minimize the execution time of a single multicast, we focus on steady-state performance. We target heterogeneous platforms, modeled by a graph where resources have different communication speeds. We show that the problem of computing the best throughput for a multicast operation is NP-hard, whereas the best throughput to broadcast a message to every node in a graph can be computed in polynomial time. Thus we introduce several heuristic...
