摘要：
A complete suite of algorithms for parallelizing compilers to generate efficient SPMD code for SOR problems is presented. By applying unimodular transformation before loop tiling and parallelization, the number of messages per iteration per processor is reduced from 3(n) - 1 in the conventional parallel SOR algorithm to 2(n) - 1, where n is the dimensionality of the data set. To maintain the memory-scalability, a novel approach to use the local dynamic memory of parallel processors to implement the skewed data set is proposed.
