NGS: Component-based Frameworks for High-Performance Distributed Scientific Applications

0203984田纳西大学的Jack J.Donarra基于组件的高性能分布式科学应用程序框架科学计算机应用程序正在继续发展，以解决更复杂的物理问题。其结果是从较小的元素应用程序构建的复合应用程序的增加，每个应用程序都对一个更简单的物理问题进行建模。由于复合应用程序通常很大，因此它们往往是由团队构建的。此外，这些复合应用程序往往使用数据并行和任务并行设计的组合分布在多台计算机上。它们通常通过文件和数据库共享数据。更复杂的设计将包括消息传递、远程事件信号和其他分布式计算技术。为了实现这一愿景，我们必须克服重大的科学和技术障碍。拟议的项目包括研究大型、复合、科学应用程序的编程模型，这些应用程序的目标是在计算机网格环境中运行。这项研究将专注于开发高效的技术来编程和执行这些应用程序，包括支持管理将元素应用程序集成到复合应用程序中的行为方面。这项研究将被用来开发一个基于组件的框架，其中可以创建此类应用程序的清晰、简洁和准确的描述，并用于在高性能的分布式环境中执行应用程序。

EIA-0203984 Jack J. Dongarra University of Tennessee Component-based Frameworks for High-Performance Distributed Scientific Applications Scientific computer applications are continuing to evolve to solve more complex physical problems. The result is an increase in composite applications that are built from smaller element applications, each of which model a simpler physical problem. As composite applications are generally large, they tend to be built by teams. In addition, these composite applications tend to be distributed over a number of computers using a combination of data-parallel and task-parallel designs. They typically share data via files and databases. More sophisticated designs will include message passing, remote event signals, and other distributed computing techniques.To realize this vision, we must overcome significant scientific and technical obstacles. The proposed project includes research on a programming model for large, composite, scientific applications that are targeted to run in computer Grid environments. This research will focus on developing efficient techniques to program and execute these applications including support for managing behavioral aspects of integrating element applications into a composite application. This research will be use to develop a component-based framework where a clear, concise, and accurate description of such applications can be created and used to execute the application in a high-performance, distributed environment.
