ITR: Grid Service Workflow System as a Research Environment for Science with Massive Data Sets

处理和分析大型数据集的传统工具不足以应对现代科学数据的数量和复杂性的增长。从不断增长的数据中挖掘新发现的能力需要创建和应用新的数据分析技术和算法。“这个项目将开发一个新的基于网格技术的系统，作为拥有海量和复杂数据集的天文学的原型研究环境。虽然天文学是一个特定的科学学科，研究人员在其中拥有专业知识，但他们正在解决的问题是大多数科学的共同问题。这个知识提取系统将使用新的IT范式建立：它将是一个由工作流系统控制的分布式网格服务库，符合网络基础设施的新兴标准……该系统将成为NSF国家虚拟天文台的一部分，大大有利于该项目和整个天文学社区。”*

AST-0326524WilliamsTraditional tools for handling and analyzing large data sets are inadequate to address the growth in volume and complexity of modern scientific data. The ability to mine new discoveries out of an ever-increasing amount of data requires the creation and application of new techniques and algorithms for data analysis. "This project will develop a novel Grid-technology based system as a prototype research environment for astronomy with massive and complex data sets. While astronomy is a particular science discipline in which the [investigators] have expertise, the problems they are solving are common to most sciences. This knowledge extraction system will be built with a new IT paradigm: it will be a library of distributed Grid Services controlled by a workflow system, compliant with the emerging standards of cyber-infrastructure...The system will become a part of the NSF National Virtual Observatory, substantially benefiting that project and the astronomical community in general."***
