    A new task scheduling heuristic for assigning tasks onto processors and communication paths to communicating task pairs at the same time is introduced. In our heuristic, we assume that the distributed system has irregular topology and each communication link connecting two processors is heterogeneous. In this environment, nonadjacent processors have to communicate through intermediate processors between them. Moreover, the communication cost on each link will increase in proportion to the amount of data loaded on the link. In this paper, we propose path assignment algorithm that greedily assign a fast communication path to communicating task pairs by avoiding data congestion on links as well as considering the distance between processors.
