A theoretical framework of data parallelism and its operational semantics

Abstract

Abstract. We developed a theory in order to address crucial questions of program design methodology. We think that it could unify two concepts of data parallel programming that we consider fundamental as they concern data locality expression: the notions of alignment in HPF and shape in C*. In this article, we aim at exploring the impact of program transformations on efficiency. For this, we define a formal operational semantics associated with the aforementioned theory
