Benchmarking has become one of the most important methods for quantitative performance evaluation of processor and computer system designs.
Benchmarking of modern multiprocessors such as chip multiprocessors is challenging because of their application domain, scalability and parallelism requirements. In my thesis, I have developed a methodology to design effective benchmark suites and demonstrated its effectiveness by developing and deploying a benchmark suite for evaluating multiprocessors.

More specifically, this thesis includes several contributions. First, the thesis shows that a new benchmark suite for multiprocessors is needed because the behavior of modern parallel programs is significantly different from those represented by SPLASH-2, the most popular parallel benchmark suite developed over ten years ago. Second, the thesis quantitatively describes the requirements and characteristics of a set of multithreaded programs and their underlying technology trends. Third, the thesis presents a systematic approach to scale and select benchmark inputs with the goal of optimizing benchmarking accuracy subject to constrained execution or simulation time. Finally, the thesis describes a parallel benchmark suite called PARSEC for evaluating modern shared-memory multiprocessors. Since its initial release, PARSEC has been adopted by many architecture groups in both research and industry.
