If the iterations of a loop nest cannot be partitioned into independent tasks, data communication for data dependence is inevitable in order to execute them on parallel machines. This kind of loop nest is referred to as a DOACROSS loop nest.This paper is concerned with compiler algorithms for parallelizing DOACROSS loop nests for distributed-memory multicomputers. We present a method that combines loop tiling, chain-based scheduling and indirect message passing to generate efficient message-passing parallel code. We present our experiment results on the Fujitsu AP1000 to show that low communication overhead and high speedup for DOACROSS loop nests on multicomputers can be achieved by tuning these techniques.
