Next Generation Software: Grid Application Development Software (GrADS)

EIA-9975020莱斯大学Kennedy，Ken W.网格应用开发软件（GrADS）这一建议将使网络技术的进步成为可能，以一种不同的方式使用全球信息基础设施-作为计算资源以及信息资源。 这种集成计算和信息资源的想法被称为计算电网（Computational Power Grid），最近出版的一本书《网格：新计算基础设施的蓝图》（The Grid：Blueprint for a New Computing Infrastructure）[40]对此进行了描述。 网格将把国家的计算机、数据库、仪器和人连接在一个无缝的网络中，支持新兴的富计算应用概念，如远程计算、分布式超级计算、远程沉浸、智能仪器和数据挖掘。 其中最重要的是可用性。 由于网格本质上比现有的计算机系统更复杂，因此在网格上执行的程序将反映这种复杂性。 网格资源将是有用的和可访问的科学家和工程师需要新的软件工具，体现了在理论和实践的重大进展，建立网格应用程序。网格应用程序开发软件（GrADS）项目的目标是简单地分布异构计算的方式一样，万维网简化了互联网上的信息共享。 GrADS项目将探索必须解决的科学和技术问题，以使网格应用程序开发和性能调优成为真实的应用程序的日常实践。

EIA-9975020Rice UniversityKennedy, Ken W.Grid Application Development Software (GrADS)This proposal will make it possible to have advances in networking technologies to use the global information infrastructure in a qualitatively different way-as a computational resource as well as and information resource. This idea for an integrated computation and information resource called the Computational Power Grid has been described by the recent book entitled The Grid: Blueprint for a New Computing Infrastructure [40]. The Grid will connect the nation's computers, databases, instruments, and people in a seamless web, supporting emerging computation-rich application concepts such as remote computing, distributed supercomputing, tele-immersion, smart instruments, and data-mining.To realize this vision, significant scientific and technical obstacles must be overcome. Principal among these is usability. Because the Grid will be inherently more complex than existing computer systems, programs that execute on the Grid will reflect some of this complexity. The Grid resources will be useful and accessible to scientist and engineers requiring new software tools that embody major advances in both the theory and practice of building Grid applications.The goal of the Grid Application Development Software (GrADS) Project is to simply distribute heterogeneous computing in the same way that the World Wide Web simplified information sharing over the Internet. The GrADS projects will explore the scientific and technical problems that must be solved to make Grid application development and performance tuning for real applications an everyday practice.
