In this paper, we consider the problem of allocating and scheduling a collection of independent, equal-sized tasks on heterogeneous star-shaped platforms. We also address the same problem for divisible tasks. For both cases, we take memory constraints into account. We prove strong NP-completeness results for different objective functions, namely makespan minimization and throughput maximization, on simple star-shaped platforms. We propose an approximation algorithm based on the unconstrained version (with unlimited memory) of the problem. We introduce several heuristics, which are evaluated and compared through extensive simulations. An unexpected conclusion drawn from these experiments is that classical scheduling heuristics that try to gr...
