CISE Research Instrumentation: A High-Bandwidth Network Testbed For Parallel Computation

该合同将购买一个由24个100MHz i486系统组成的集群，这些系统通过以太网和由3个12端口ATM交换机组成的ATM网络连接。每个i486系统都有足够的主内存来允许在集群上运行大型并行计算，并且有足够的磁盘空间来允许执行并行I/O实验。这些设备将专门用于支持计算机和信息科学与工程方面的研究。该设备将用于若干研究项目，其中特别包括：利用专用高带宽网络在高速处理器集群上执行数据并行程序；数据并行编程模型扩展的设计、实现和评估，以支持并行I/O；UNH Flexidesc系统的并行实施，该系统集成了科学数据可视化和数据库技术，支持科学数据的探索性分析；图形和数据可视化并行算法的发展；求解约束满足问题的并行算法的发展。＊＊＊

9421997 Hatcher This award is to purchase a cluster of 24 100MHz i486 systems connected via both an Ethernet and an ATM network constructed from 3 12-port ATM switches. Each i486 system will have sufficient main memory to allow large parallel computations to be run on the cluster and sufficient disk space to allow parallel I/O experiments to be performed. This equipment will be dedicated to supporting research in computer and information science and engineering. The equipment will be used for several research projects, including in particular: the implementation of data-parallel programs on clusters of high-speed processors utilizing a dedicated high-bandwidth network; the design, implementation and evaluation of extensions to the data-parallel programming model to support parallel I/O; the parallel implementation of the UNH Flexidesc system, which integrates scientific data visualization and database technology to support exploratory analysis of scientific data; the development of parallel algorithms for graphics and data visualization; the development of parallel algorithms for solving constraint satisfaction problems. ***
