National Science FoundationDistributed Systems Research CISE/CNSABSTRACTPROPOSAL NUMBER: 0410918PRINCIPAL INVESTIGATOR: Debray, Saumya K.INSTITUTION: U of Arizona PROPOSAL TITLE: A Holistic Approach to Compiler-Assisted Optimization of Software Systems This project aims to improve computer software by considering the operating system and application programs running on a processor together in a holistic manner, and consider-ing global as well as individual behaviors of such systems. Each component of a com-puter system, i.e., the operating system and the different applications, runs in its own ad-dress space. Existing approaches to software optimization consider these components as isolated entities and assume nothing about the behavior of, or interactions with, other ad-dress spaces. This has the shortcoming that the software improvement process cannot take advantage of knowledge of interactions between code modules in the different ad-dress spaces. This project aims to develop tools and techniques to address this shortcom-ing. A key element in our approach is the use of compiler techniques in novel ways, and in particular, in a multi-address space systems context rather than a single address space application-level context.The impact of this work will be to improve the performance of software systems across a wide variety of contexts and according to several different metrics. In particular, we ex-pect to be able to improve user applications, operating systems kernels, and system ser-vices, with performance metrics that include execution speed, amount of memory re-quired, fault tolerance, and enhanced security. Our results will be disseminated in the form of publications describing our algorithms, experimental methodology and results, as well as software developed as part of the project, which we will make available via the World-wide web.Dr. Brett D.

国家科学基金会分布式系统研究CEISE/CNSABSTRACTPROPOSAL编号：0410918 PRINCIPAL调查员：Debray，Saumya K.INSTITUTION：亚利桑那大学提案标题：编译器辅助的软件系统优化的整体方法这个项目旨在通过以整体的方式一起考虑在处理器上运行的操作系统和应用程序，并考虑这种系统的全局和个体行为来改进计算机软件。计算机系统的每个组件，即操作系统和不同的应用程序，在其自己的广告空间中运行。现有的软件优化方法将这些组件视为孤立的实体，并且不假设其他广告空间的行为或与其交互。这具有软件改进过程不能利用不同广告空间中的代码模块之间的交互的知识的缺点。该项目旨在开发工具和技术来解决这一不足。我们方法中的一个关键因素是以新颖的方式使用编译器技术，特别是在多地址空间系统上下文而不是单一地址空间应用级上下文中。这项工作的影响将是提高软件系统在各种上下文中的性能并根据几个不同的度量标准。特别是，我们期望能够改进用户应用程序、操作系统内核和系统服务，性能度量包括执行速度、所需内存量、容错性和增强的安全性。我们的成果将以出版物的形式传播，介绍我们的算法、实验方法和结果，以及作为项目一部分开发的软件，我们将通过万维网提供这些软件。布雷特·D·弗莱施项目总监，CEISE/CNS2004年6月24日
