This article is devoted to the redistribution of one-dimensional arrays that are distributed in a GEN_BLOCK fashion over a processor grid. While GEN_BLOCK redistribution is essential for load balancing, prior research about redistribution has been focused on block-cyclic redistribution. The proposed scheduling algorithm exploits a spatial locality in message passing from a seemingly irregular array redistribution. The algorithm attempts to obtain near optimal scheduling by trying to minimize communication step size and the number of steps. According to experiments on CRAY T3E and IBM SP2, the algorithm shows good performance in typical distributed memory machines.
