Abstract

In this paper we describe a C++ infrastructure for source-to-source translation. Wedemonstrate the translation of a serial program with high-level abstractions to a lower-level parallel program in two separate phases. In the first phase OpenMP directives are introduced, driven by the semantics of high-level abstractions. Then the OpenMP directives are translated to a C++ program that explicitly creates and manages parallelism according to the specified directives. Both phases are implemented using the same mechanisms in our infrastructure.
