This research concerns the performance of parallel systems, and in particular of homogeneous shared-memory multiprocessors. These systems are just now becoming available, show promise of proividing cost- effective high-performance computing for the near-term future, and present a wide range of unsolved problems, many of which apply to other system architectures as well. They will study three specific areas. The first is the influence of software structure on system performance; we will explore the sources of degradation in parallel systems and the relationships among these sources of degradation, providing guidelines for the construction of parallel software that performs well. The second is software control policies for parallel systems; they will develop and evaluate techniques that yield both good program speedup and good system efficiency. The third is performance tools on and for parallel systems; They will build performance debugging tools for parallel programs, and performance modelling tools that address the problems of parallel systems and that exploit parallelism themselves.

本研究关注并行系统的性能， 特别是同构共享内存多处理器。 这些系统 现在才开始出现，显示出提供成本的承诺- 为近期的未来提供高效的高性能计算， 提出了广泛的未解决的问题，其中许多适用于其他 系统架构也是如此。 他们将研究三个具体领域。 第一个是影响， 软件结构对系统性能的影响;我们将探讨 并行系统中的退化和这些之间的关系 退化的来源，为建造 运行良好的并行软件。 二是软件控制 并行系统的政策;他们将制定和评估 一种既能产生良好的程序加速又能产生良好的系统性能的技术 效率 第三个是并行性能工具 系统;他们将构建并行性能调试工具 程序，和性能建模工具，解决的问题， 并行系统和利用并行性本身。
