CISE Research Instrumentation: Equipment for Diverse Computer Architecture Research

9729839 UHT，奥古斯都·K·罗德岛大学研究仪器：用于多样化计算机体系结构研究的设备这项研究仪器拨款支持三个不同的研究项目：-在10‘S中实现指令级并行-用于高性能磁盘I/O的层次化存储体系结构的新光谱-超可靠和高性能分布式计算，同时寻求在多个维度提高计算机性能：单处理器或微处理器、I/O(输入/输出)系统和多计算机系统。此外，还将提高多计算机系统的可靠性。这些目标将通过以几种不同方式使用新的仪器设备(多处理器和多磁盘阵列存储系统)来实现。首先，将在新的多处理器上设计和仿真Levo研究原型单处理器。后者将用于验证Levo的实现和测量其性能，以及允许Levo的构建，从而确定单处理器可以被设计为每个周期执行比当前单处理器多一个数量级的指令。其次，由于I/O约束会限制整体性能，新型磁盘缓存磁盘(DCD)I/O系统将在新的多处理器和RAID设备上实现，展示了DCD体系结构的2到数量级的性能改进。最后，主动节点任务搜索(ANTS)分布式计算系统在粗粒度环境下实现了高性能和超可靠性。新的蚂蚁内核将在新的多处理器上实现，这表明在细粒度应用程序上也可以实现相同的功能。

9729839 Uht, Augustus K. University of Rhode Island Research Instrumentation: Equipment for Diverse Computer Architecture Research This research instrumentation grant enables three distinct research projects: - Realizing Instruction Level Parallelism in the 10's - A New Spectrum of Hierarchical Storage Architectures for High Performance Disk I/Os - Ultra-Dependable and High-Performance Distributed Computing while seeking to improve computer performance in many dimensions: uni- or micro-processors, I/O (Input/Output) systems, and multiple-computer systems. Further, the reliability of multiple-computer systems is to be enhanced. These objectives are to be achieved by using the new instrumentation equipment (multiprocessor and multiple-disk RAID storage system) in several different ways. First, the Levo research prototype uniprocessor is to be designed and simulated on the new multiprocessor. The latter will serve to verify Levo's implementation and measure its performance, as well as to allow Levo's construction, establishing that uniprocessors can be designed to execute an order-of-magnitude more instructions per cycle than current uniprocessors. Second, since I/O constraints can limit overall performance, the novel Disk Caching Disk (DCD) I/O system is to be realized on the new multiprocessor and RAID equipment, demonstrating factors of 2 to orders-of-magnitude performance improvements of the DCD architecture. Lastly, the Active Nodal Task Seeking (ANTS) distributed computing system achieves high performance and ultra-dependability in a coarse-grain environment. The new ANTS kernel is to be realized on the new multiprocessor, showing that the same can be achieved on fine-grain applications.
