Efficient generation of stream programs from loops

The efficiency of scientific applications on the Imagine stream processor is increasingly concerned by researchers. One of the obstacles is that the programming language of Imagine does not target the scientific computing. This paper introduces a program transformation algorithm to automatically transform loops to the stream programs executed on Imagine. The optimization for memory accessing is also considered during the transformation. We have implemented the transformation and optimization algorithm with the GFORTRAN frontend. Preliminary results over benchmark kernels show that our approach is a convenient and efficient solution to develop scientific applications on the Imagine stream processor.
