A Laboratory for Parallel Programming

这项提议是建立平行应用程序和软件实验室的第一阶段，该实验室将成为印第安纳大学创新计算机应用中心(CICA)的组成部分。这个实验室将利用现有中心的资源，提供一个设施，在那里，训练有素的人员将直接与来自不同学科的科学家合作，设计新的并行应用程序，并研究用于并行编程、程序重组和性能可视化的专门工具的有效性。该实验室的研究任务将是利用现实世界应用领域来研究设计可伸缩并行软件的问题。我们这个实验室的具体研究项目是：(1)将现有的并行编程工具应用于物理和社会科学的实际应用中，并对其进行评估。(2)研究高层、面向对象的抽象机制在并行应用程序设计中的应用。特别是，我们将使用一种基于面向对象设计的新编程方法，它将允许我们为各种大规模并行体系结构编译程序。(3)扩展性能分析工具的最新水平，以便它们能够随着机器和问题大小的扩大而预测性能。这涉及到新一代算法可视化工具的设计，该工具将并行复杂性模型和并行程序的静态和动态分析与机器行为的分析模型相结合。

This proposal is the first phase in establishing a Parallel Applications and Software Laboratory that will be a component of the Indiana University Center for Innovative Computer Applications (CICA). This laboratory will build upon the resources of an established center to provide a facility where a staff of trained people will work directly with scientists from a variety of disciplines to design new parallel applications and to study the effectiveness of specialized tools for parallel programming, program restructuring and performance visualization. The research mission of the laboratory will be to use the domain of real world applications to study the problem of designing scalable parallel software. Our specific research projects for this laboratory are: (1) To apply and evaluate existing parallel programming tools to real applications in the physical and social sciences. (2) To investigate the utility of higher level, object oriented abstraction mechanisms in the design of parallel applications. In particular, we will use a new programming methodology based on object oriented design that will allow us to compile programs for a wide variety of massively parallel architectures. (3) To extend the state of the art in performance analysis tools so that they are able to predict performance as machine and problem sizes are scaled. This involves the design of a new generation of algorithm visualization tools that incorporates parallel complexity models and static and dynamic analysis of parallel programs with analytical models of machine behavior.
