All existing methods for automated data/computation decomposition share a common failing: they are very sensitive to the original loop structure of the program. While they find a good decomposition for that loop structure, it may be possible to apply transformations (such as loop interchange and distribution) so that a different decomposition gives even better results. We have developed automatic computation decomposition methods that are not sensitive to the original program structure. We can… CONTINUE READING
