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

CDA-9529459 Michael W.马克·T.詹姆斯·琼斯普兰克·帕德玛·拉加万 田纳西大学 一个ATM联网的12个高性能工作站支持田纳西大学计算机科学系的几个研究项目，特别是包括：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，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。 该计算实验室为计算密集型项目提供所需的CPU时间，本地内存，通信带宽和磁盘存储资源。 一些研究任务需要这个专门的实验室，因为它们的运行时间非常长。 系统项目需要访问这样的环境来运行有意义的实验。 此外，专用实验室设施可以重新配置或经受模拟故障，而不必担心对其他用户的影响。 这些研究项目将产生公共领域的软件。 由于几个政府和工业场所很快就会有类似于我们建议的设施，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至关重要。

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.
