Previously the authors introduced the basic concept of pipelined data parallel algorithms and discussed the modeling of such algorithms on distributed-memory multicomputers. In this paper, a methodology for designing pipelined data-parallel algorithms on multicomputers is studied. The design procedure starts with a sequential algorithm which can be expressed as a nested loop with constant loop-carried dependencies. The main focus of the procedure is on partitioning the loop by grouping related iterations together. Grouping is necessary to balance the communication overhead with the available parallelism and to produce pipelined execution patterns, which result in pipelined data parallel computation. The group should satisfy dependence relationships among the iterations and also allow the granularity to be controlled. Various properties of grouping are studied, and methods for generating communication efficient grouping are given.
