Summary:
This paper aims at developing a scheduling method for multiprocessor systems with communication time. In this paper, we firstly propose a model of multiprocessor system with communication time occurring in reading data. Then, for the proposed model, we propose a scheduling method (called AMCN scheduling method) that (i) divides a task graph to subgraphs so that a task (called node hereafter) and its successors and predecessors are as much as possible included in the same subgraph to shorten communication time; and (ii) uses a fixed processor to execute all the nodes of a subgraph. Finally, we do computational simulation experiments to evaluate our scheduling method.
