9410063 Li This proposal research is to study the system architectural model and system software support of network of personal workstations (NPW) connected by SCI (Scalable Coherence Interface, IEEE Standard 1596). Oppose to the traditional LAN-connected NPW, SCI- connected NPW can provide physically shared memory and cache coherence among workstations across a network with high bandwidth (1Gbyte/sec) and low latency (microseconds). The research will provide the understanding of the new parallel architecture which is highlighted by contradiction between its closely-coupled nature due to shared memory and cache coherence and its loosely- coupled nature due to the physical distance between workstations and independent operations of the workstations. This research will result in models of various designs of SCI-connected NPW and their comparisons, operating system designs to support such architectures, and performance data based on typical parallel applications. The result will be an important step towards inexpensive but powerful and widely available parallel computing platforms. The work will be done in three steps: (1) Model the architectural characteristics of SCI-connected NPE. (2) Design and implement operating system software supports based on the hardware and applications requirements. System level performance will also be studied. (3) Design and implement application prototypes to obtain performance data. Simulation will be used to predict the performance of large scale SCI-NPWs. ***

本课题研究的是SCI（Scalable Coherence Interface，IEEE Standard 1596）连接的个人工作站网络的系统结构模型和系统软件支持。 与传统的LAN连接NPW相反，SCI连接NPW可以在网络中的工作站之间提供物理共享内存和高速缓存一致性，具有高带宽（1GB/秒）和低延迟（微秒）。 该研究将提供新的并行体系结构的理解，这是突出的矛盾之间的紧密耦合的性质，由于共享内存和高速缓存的一致性和松散耦合的性质，由于工作站之间的物理距离和独立的操作的工作站。 这项研究将导致SCI连接的NPW的各种设计的模型和它们的比较，操作系统的设计，以支持这种架构，并基于典型的并行应用程序的性能数据。 其结果将是迈向廉价但功能强大且广泛可用的并行计算平台的重要一步。 工作分三步进行：（1）建立SCI连接的NPE的体系结构模型。 (2)根据硬件和应用需求设计和实现操作系统软件支持。 还将研究系统级性能。 (3)设计和实现应用程序原型以获取性能数据。 模拟将用于预测大型SCI-NPWs的性能。 ***
