We describe the Cetus compiler infrastructure and its use in a number of transformation tasks for multicore architectures. The original intent of Cetus was to serve as a parallelizing compiler. In addition, the infrastructure has been used to build translators for programs written in the OpenMP directive language to be compiled onto multicore architectures. They include a direct OpenMP translator for current multicores, an OpenMP to MPI translator for many-cores exhibiting disjoint address

This feature is especially important for heterogeneous multicore architectures. We will describe the organization of the Cetus infrastructure and present preliminary results of several application projects.
