Abstract
Group communication significantly influences the performance of data parallel applications. It is required often in two situations: one is array redistribution from phase to phase; the other is array remapping after loop partition. Nevertheless, the important factor that influences the efficiency of group communication is often neglected: a larger communication idle time may occur when there is node contention and difference among message lengths during one particular communication step. This paper is devoted to develop an efficient scheduling strategy using the compiling information provided by array subscripts, array distribution pattern and array access period. Our strategy not only avoids inter-processor contention, but it also minimizes real communication cost in each communication step. Our experimental results show that our strategy has better performance than the traditional implement of MPI_Alltoallv, alltoall based scheduling, and greedy scheduling.
