CISE Research Instrumentation: High-Performance ATM Network for Computational Science

Cda-9529459 Michael W.Berry Jens Gregor Mark T.Jones James S.Plank Padma Raghavan University of Tennessee一台ATM联网的12台高性能工作站支持田纳西大学计算机系的几个研究项目，尤其包括：分布式计算环境中的科学应用，分布式环境中的PET图像重建，用于非结构化网格计算的并行算法和软件，并行环境中的快速检查点，以及并行稀疏矩阵计算。这个计算实验室为计算密集型项目提供了所需的CPU时间、本地内存、通信带宽和磁盘存储资源。有些研究任务需要这个专门的实验室才能完成超长的运行时间。该系统工程需要进入这样的环境才能进行有意义的实验。此外，专用实验室设施可以重新配置或经历模拟故障，而不会考虑对其他用户的影响。这些研究项目将生产公共领域软件。由于几个政府和工业场所将很快拥有与我们建议的设施类似的设施，因此定期访问这样的实验室对于高质量的软件研究和开发是必不可少的。

CDA-9529459 Michael W. Berry Jens Gregor Mark T. Jones James S. Plank Padma Raghavan University of Tennessee An ATM networked 12 high-performance workstations supports several research projects in the Computer Science Department at the University of Tennessee, including in particular: Scientific Applications in a Distributed Computing Environment, PET Image Reconstruction in a Distributed Environment, Parallel Algorithms and Software for Unstructured Mesh Computations, Fast Checkpointing in Parallel Environments, and Parallel Sparse Matrix Computations. This computing laboratory provides required resources of CPU time, local memory, communication bandwidth and disk storage for the computationally intensive projects. Some of the research tasks require this dedicated laboratory for their exceptionally long runtimes. The systems project requires access to such an environment to run meaningful experiments. In addition, the dedicated laboratory facilities may be reconfigured or subjected to simulated faults without concern about the effects on other users. The research projects will produce public-domain software. Because several government and industrial sites will soon have facilities similar to that which we propose, regular access to such a laboratory is essential for quality software research and development.
