Experimental Software Systems: Distributed Resource Management in Local-Area and Wide-Area Networks

Levy, Henry M. Karlin, Anna R.华盛顿大学ESS：局域网和广域网中的分布式资源管理网络和处理器技术的进步极大地改变了联网计算机的通信和计算能力。然而，当前的软件系统无法利用现代硬件组件的功能，因为它们是为上一代硬件设计的。这项研究的目标是通过设计和实现更适合未来硬件特征的新软件结构和算法，使未来的网络和处理器能够更有效地使用。研究集中在两个相关但独立的领域。首先，在局域网（集群）中，这项工作旨在通过分布式的、集群范围的资源管理来提高应用程序的性能。它将开发允许所有集群范围的网络资源紧密共享的算法：处理器、网络、内存和磁盘存储。其次，本研究试图将全球资源管理的经验应用到更广泛的领域——全球互联网。该项目将开发和测试算法，以优化和动态地定位互联网中的数据和计算，以改善数据访问延迟并降低网络带宽利用率。这项研究的一个重要组成部分是构建一个软件模拟基础设施，以测试适用于像全球网络这样的大规模系统的假设。

EIA-9870740 Levy, Henry M. Karlin, Anna R. University of Washington ESS: Distributed Resource Management in Local-Area and Wide-Area Networks Advances in network and processor technology are greatly changing the communication and computational power of networked computers. However, current software systems are unable to utilize the capabilities of modern hardware components, because they are designed for last-generation hardware. The goal of this research is to enable more effective use of future networks and processors through design and implementation of new software structures and algorithms better suited to the characteristics of future hardware. The research focuses on two related but independent domains. First, in local-area networks (clusters), this work seeks to improve the performance of applications through distributed, cluster-wide resource management. It will develop algorithms that permit the tight-knit sharing of all cluster-wide network resources: processors, network, memory, and disk storage. Second, this research seeks to apply experience in global resource management to a much broader domain -- the global Internet. The project will develop and test algorithms that optimally and dynamically locate both data and computation in the Internet, in order to improve data-access latencies and reduce network bandwidth utilization. A significant component of this research is the construction of a software simulation infrastructure to test hypotheses applied to such a large-scale system as the world-wide web.
