| Abstract: | This paper deals with communication optimization which is a crucial issue in automatic parallelization. From a system of parameterized affine recurrence equations we propose a heuristic that determines a set of efficient space-time transformations. It focuses on distant communications removal using broadcast—including anticipated broadcast, and locality enforcement. |
