Maximizing multiprocessor performance with the SUIF compiler

This paper presents an overview of the SUIF compiler, which automatically parallelizes and optimizes sequential programs for shared-memory multiprocessors. We describe new technology in this system for locating coarse-grain parallelism and for optimizing multiprocessor memory behavior essential to obtaining good multiprocessor performance. These techniques have a signi cant impact on the performance of half of the NAS and SPECfp95 benchmark suites. In particular, we achieve the highest SPECfp95 ratio to date of 63.9 on an eight-processor 440MHz Digital AlphaServer.
