MRA: High Performance Computing, Information Serving, and Data Visualization on Clusters of Shared Memory Multiprocessors

9523480 Woodward提出与NSF Metacenter合作开发由共享内存多处理器（SMP）集群组成的新兴超级计算机体系结构的有效使用。将讨论的用途不仅包括高性能计算，还包括在国家信息基础设施上提供高性能数据和多媒体服务，以及对非常大的数据集进行科学可视化。在明尼苏达大学一个新的计算科学与工程实验室（LCS&amp；E）的支持下，一个强大的研究团队在集群SMP和密切相关的计算机体系结构方面具有丰富的经验。利用慷慨的长期设备贷款以及现有的基础设施，该团队将与计算机行业在系统集成和软件开发方面密切合作，并与metcenter在应用程序开发方面密切合作。因为我们对这个新的Silicon Graphics架构有共同的兴趣；该MRA将特别与NCSA密切合作。然而，这个metcenter区域联盟的工作最终打算移植到其他供应商的集群SMP体系结构的实现上，因此应该适用于IBM SP-3 （Cornell）、Cray J90 （Pittsburgh）以及Convex Exemplar （NCSA）。这个MRA团队开发了Wgl分辨率电源墙显示系统，并在1994年超级计算大会上进行了演示。lcse团队将与NCSA和电子可视化实验室合作，通过其最近资助的MRA，帮助将这项技术应用于这些站点，特别是在超级计算95年的I-WAY（信息广域年）演示中。由于明尼苏达团队在为工作站构建非常高性能的磁盘I/O子系统方面进行了广泛的工作，因此也期望与加州理工学院的并行I/O计划（另一个最近的MRA）建立有用的关系。最后，lcse团队将与当地内城高中以及代表明尼苏达州45个学区的TIES组织合作，在整个明尼苏达州提供K-12扩展服务。

9523480 Woodward A collaboration with the NSF Metacenter to develop effective uses of the emerging supercomputer architecture consisting of a cluster of shared memory multiprocessors (SMP's) is proposed. Uses which will be addressed include not only high performance computing, but also providing high performance data and multimedia services over the National Information Infrastructure and scientific visualization of very large data sets. A strong team of researchers with considerable experience with the clustered SMP and closely related computer architectures has been assembled under the auspices of a new Laboratory for Computational Science and Engineering (LCS&E) at the University of Minnesota. Exploiting generous long-term loans of equipment as well as existing infrastructure, this team will work closely with the computer industry on system integration and software development and with the Metacenter on application development. Because of a shared interest in this new Silicon Graphics architecture; this MRA will collaborate especially closely with NCSA. However, the work of this Metacenter Regional Alliance is ultimately intended to be portable to other vendors' implementations of the clustered SMP architecture, and therefore should be applicable to the IBM SP-3 (Cornell), the Cray J90 (Pittsburgh), as well as the Convex Exemplar (NCSA). This MRA team developed the Wgl resolution Power Wall display system and demonstrated it at Supercomputing '94. The LCS&E team will work with NCSA and the Electronic Visualization Laboratory through its recently funded MRA, to help bring this technology into use at those sites and, particularly, at the I-WAY (Information Wide Area Year) demonstration at Supercomputing '95. Because of the Minnesota team's extensive work in building very high performance disk I/O subsystems for workstations, a useful relationship with the Parallel I/O Initiative at Caltech, another recent MRA, is also anticipated. Finally, the LCS&E team will work together with local inner city high schools and with the TIES organization representing a consortium of 45 Minnestoa school districts to provide K-12 outreach throughout the state of Minnesota.
