Optimizing Storage Size for Static Control Programs in Automatic Parallelizers

Abstract

. This article deals with automatic parallelization of static control programs. During the parallelization process the removal of artificial dependences is usually realized by translating the original program into a single assignment form. This total data expansion has a very high memory cost. We present a technique of partial data expansion which leaves untouched the performances of the parallelization process, with the help of algebra techniques given by the polytope model. 1 Introduction This article deals with the automatic parallelization technique based on the polytope model. This method can be applied provided that source programs are static control programs, i.e. are limited to do loops and assignment statements to array with affine subscripts. The first step is an array data flow analysis in order to extract exact dependences on memory cells. All artificial dependences, which are due to reuse of data, are deleted by a total data expansion. The transformed program has the sing..
