CISE Research Instrumentation: A Next-Generation High Performance Network of Commodity PCs

Ibarra, Oscar H. Rinard, Martin C. Schauser, Klaus E. Yang，加州大学圣巴巴拉分校下一代商用个人电脑高性能网络所提出的仪器由由商用ATM网络连接的商用个人电脑（pc）集合组成。该计算平台支持高性能并行和分布式系统领域的四个实验研究项目。第一个项目为经济有效的商品计算和网络平台研究有效的通信原语。目标是使重要的并行计算能够在此计算环境中有效地执行。第二个项目研究一种新的并行编译器技术，称为交换性分析。我们的目标是扩展并行编译器的范围，以包括操作复杂的基于指针的数据结构的计算。第三个项目研究不规则科学计算的调度和运行时支持技术。目标是了解如何将这些计算有效地映射到由商用硬件组件组成的现代并行计算环境。最后的项目研究了为数字图书馆应用程序开发可扩展的WWW服务器的问题。目标是加强服务器的处理能力，以匹配来自Internet的同时访问请求的巨大预期增长。所有这些项目的主要研究活动是开发、测试和测量软件。工具提供了执行这些活动所需的硬件平台。

CDA 9529418 Ibarra, Oscar H. Rinard, Martin C. Schauser, Klaus E. Yang, Tao University of California, Santa Barbara A Next-Generation High-Performance Network of Commodity PCs The proposed instrumentation consists of a collection of commodity personal computers (PCs) connected by a commodity ATM network. This computing platform supports four experimental research projects in the area of high performance parallel and distributed systems. The first project investigates efficient communication primitives for cost-effective commodity computing and networking platforms. The objective is to enable important parallel computations to execute efficiently in this computing environment. The second project investigates a new parallelizing compiler technique called commutativity analysis. The objective is to extend the range of parallelizing compilers to include computations that manipulate complex pointer-based data structures. The third project investigates scheduling and run-time supporting techniques for irregular scientific computations. The objective is to understand how to map these computations efficiently onto a modern parallel computing environment consisting of commodity hardware components. The final project investigates issues in developing a scalable WWW server for digital library applications. The objective is to strengthen the server's processing capabilities to match huge expected increases in simultaneous access requests from the Internet. The main research activity in all of these projects is developing, testing and measuring software. The instrumentation provides the hardware platform required to perform these activities.
