One of the most important collective communication patterns used in scientific applications is the complete exchange, also called all-to-all. Although efficient complete exchange algorithms have been studied for specific networks, general solutions like those available in well-known MPI distributions (e.g. the MPI_Alltoall operation) are strongly influenced by the congestion of network resources. In this paper we present an integrated approach to model the performance of the all-to-all… CONTINUE READING
