CISE Research Instrumentation: High-Speed Cluster of Workstations

小行星9421978 该合同将用于购买一个ATM网络，该网络将用于多个研究项目：设计一个评估共享存储器和一致性协议的平台，网络研究，图像数据库和高性能交易处理。 分布式共享存储器的研究将扩展现有的仿真和评估平台，提供有效的接口，实现对象，容错和模拟使用语义信息。 网络研究将处理ATM网络设计，建模和应用中的一些关键问题：流量整形，异构流量建模和测量，IP流量在ATM上的传输，以及支持多媒体应用的本地模式ATM协议栈的设计和构建。 关于图像数据库的项目将在动态和自适应索引结构的帮助下探索有效的基于内容的图像检索机制。 总体目标是支持高效的相似性查询以及开发快速浏览技术。 最后，高性能事务处理的研究将使用弱存储器和数据划分技术来实现和研究无共享系统的性能。 ***

9421978 Singh This award is to purchase an ATM network which will be used for several research projects: design of a platform for evaluating shared memories and coherence protocols, networking research, image databases, and high performance transaction processing. The proposed research on distributed shared memories will extend an existing simulation and evaluation platform by providing efficient interfaces, implementation of objects, fault tolerance, and simulation using semantic information. The networking research will deal with a number of critical issues in ATM network design, modeling, and applications: traffic shaping, heterogeneous traffic modeling and measurement, the delivery of IP traffic over ATM, and the design and construction of native-mode ATM protocol stacks to support multimedia applications. The project on image databases will explore efficient content-based image retrieval mechanisms with the help of dynamic and adaptive index structures. The overall goal is to support efficient similarity queries as well as to develop fast browsing techniques. Finally, the proposed research on high performance transaction processing will implement and study the performance of a shared nothing system using weak memories and data partitioning techniques. ***
