Abstract(in English) | Recently, systems such as PCs/Workstations clusters comprise of different kinds of nodes and connected over different kinds of networks. Efficient collective communication operations are necessary and have been studied in these systems. In this paper, we propose heuristic scheduling algorithms for efficient gather operations in these systems. We also evaluate them by simulation. The results of simulation show that gather operations scheduled by proposed algorithms are more efficient than sequential gather operations in distributed heterogeneous systems. The results also show that the efficiency of gather operations scheduled by them depend on the ratio of the cost that depends on the message size to the cost that does not depend on the message size in point-to-point communication. |
