9729858 Franklin, Mark A. Washington University CISE Research Instrumentation: Equipment in Support of Parallel Processing Research This research instrumentation enables research in the following areas:- Patterns and Image Recognition,- Computational Biology, and- Discrete Event Simulation. The instrumentation grant funds the purchase of UtraSPARC II processors, data storage, interfaces, backup disk, and software. The parallel processor will support research requiring considerable computational resources to sustain current efforts and make additional progress. A brief description of the projects follows. - Mammogram Screening: Research will continue in the development of automated means for detecting cancer from mammograms. The goal is to improve existing parallel implementations for effective clinical usage. The techniques employed combine the technologies of artificial neural networks and wavelet transforms. - MCD (Multiple Complete Digestion) Mapping: Research will continue on a form of high-resolution, restriction-fragment DNA mapping (MCD mapping). The mapping problem is fundamental to DNA based genetic research. With genomes of enormous size (millions to billions of base pairs), even relatively simple support activities such as software testing are extremely time consuming. The requested equipment will be used to develop parallel algorithms which are faster and more accurate. - Discrete-Event Simulation: Research will continue on developing parallel discrete-event simulation algorithms for modeling large computer communications networks. Effective network designs are needed for the continued expansion and improvement of the Internet and World Wide Web. Parallel simulation techniques will be used to evaluate system performance when relatively rare events occur. For example, blocking probability evaluation in modest sized networks requires processing more than 10 trillion events.

9729858 Franklin, Mark A. 华盛顿大学 CISE 研究仪器：支持并行处理研究的设备 该研究仪器支持以下领域的研究：- 模式和图像识别，- 计算生物学，以及- 离散事件模拟。 仪器补助金用于购买 UtraSPARC II 处理器、数据存储、接口、备份磁盘和软件。并行处理器将支持需要大量计算资源的研究，以维持当前的努力并取得进一步的进展。以下是这些项目的简要描述。 - 乳房X光检查：研究将继续开发通过乳房X光检查检测癌症的自动化方法。目标是改进现有的并行实施，以实现有效的临床使用。所采用的技术结合了人工神经网络和小波变换技术。 - MCD（多重完全消化）图谱：将继续研究高分辨率限制性片段 DNA 图谱（MCD 图谱）。绘图问题是基于 DNA 的遗传研究的基础。 由于基因组规模巨大（数百万到数十亿碱基对），即使是相对简单的支持活动（例如软件测试）也非常耗时。所请求的设备将用于开发更快、更准确的并行算法。 - 离散事件仿真：研究将继续开发用于大型计算机通信网络建模的并行离散事件仿真算法。 互联网和万维网的持续扩展和改进需要有效的网络设计。当相对罕见的事件发生时，将使用并行仿真技术来评估系统性能。 例如，中等规模网络中的阻塞概率评估需要处理超过 10 万亿个事件。
