To exploit more parallelism in programs, superscalar multiprocessor systems, which exploit both fine-grained and coarsegrained parallelism, have been the trend in designing high-speed computing systems. Recently, the authors have developed a simulator for evaluating superscalar multiprocessor systems. This simulator models both a superscalar processor that can exploit instruction-level parallelism, and a shared-memory multiprocessor system that can exploit task-level parallelism. This simulator was used to run four applications chosen from the SPLASH-2 benchmark suite, and collected some performance data to investigate the parallelism exploitation capability of the superscalar multiprocessor systems in various configurations. It was observed that the instruction-level and task-level parallelism in programs can be exploited well by a moderate degree of superscalar processing and a high degree of multiprocessing. For example, the speedup of a 32-way multiprocessor with eight-issue processors can be over 200 relative to a single-issue uniprocessor.
