ITR: A Portal to the Distributed Computer Grid for the CMS Experiment at LHC

该提案要求支持威斯康星大学的一个小组开发一个门户，以促进使用没有专门配置用于特定项目的计算机无缝访问全球网格。所开发的技术将普遍适用于各种计算密集型项目，包括高能物理实验CMS（在欧洲核子研究中心的大型强子对撞机，瑞士）。它将利用GriPhyN（网格物理网络）、iVDGL（国际虚拟网格实验室）和PPDG（粒子物理数据网格）项目开发的工具。建议的活动是开发一个对象IO模型，允许本地缓存和有组织的数据流到中央服务器；调整CMS模拟程序以利用丰富的CPU资源；并利用上述项目建立按需CMS模拟设施。交付成果将以这样一种方式实现，即可以将其推广到其他项目，并且经过验证的软件工具将免费提供。

This proposal requests support for a group from the University of Wisconsin to develop a portal to facilitate the seamless access to the world-wide grid with computers that are not specially configured for the use of a particular project. The techniques developed will have general applicability to various computing intensive projects, including the high energy physics experiment CMS (at the Large Hadron Collider at CERN, Switzerland). It will leverage the tools developed by the GriPhyN (Grid Physics Network), iVDGL (international Virtual Grid Laboratory) and the PPDG (Particle Physics Data Grid) projects.The proposed activities are to develop an object IO model that allows local caching and organized streaming of data to central servers; to adapt a CMS simulation program to take advantage of an abundance of CPU resources; and to establish an on-demand CMS simulation facility using the above items. The deliverables will be implemented in such a way that generalization to other projects is possible and the validated software tools will be made freely available.
