项目摘要

This project is at the interface between Information Technology and Nuclear Physics. We will develop and apply a two-site data grid at Stony Brook and Brookhaven National Laboratory to analysis of heavy ion collisions in the PHENIX experiment at the Relativistic Heavy Ion Collider. Collisions at RHIC produce many thousands of particles, resulting in enormous volumes of data to analyze. In order to study the rare process of gluon scattering at large angle, and how the nuclear medium affects this process, we must sift through hundreds of millions of these complex events. We will use the software tools developed by the Globus collaboration to allow seamless data analysis across two computer facilities comprising many computers and terabytes of disk storage. Jobs will be automatically directed to the facility where requested data are disk resident, and results returned to the user. We will take advantage of many developments by others in information technology, but we bring to the table a unique mix of real data, eager users, and a cutting edge data grid application with a simple demonstration grid of two nearby sites with very similar hardware.Testing and optimizing this prototype grid under "battle" conditions will provide information applicable to development of large-scale global data grids for the future, as well as physics results from PHENIX.

该项目位于信息技术与核物理学之间的接口。我们将在Stony Brook和Brookhaven National Laboratory开发并应用两个站点的数据网格，以分析相对论重离子对撞机的Phenix实验中的重离子碰撞。 RHIC的碰撞产生数千个颗粒，导致大量数据进行分析。为了研究少数角度散射的罕见过程，以及核介质如何影响这一过程，我们必须筛选数亿此类复杂事件。我们将使用Globus协作开发的软件工具，以允许在两个计算机设施中进行无缝数据分析，其中包括许多计算机和磁盘存储的Terabytes。作业将自动将其定向到设施，并在所需的数据为磁盘驻留，结果返回给用户。我们将利用其他人在信息技术领域的许多发展，但是我们将真实数据，渴望用户和尖端数据网格应用程序的独特组合和简单的演示网格应用以及具有非常相似硬件的两个附近站点的简单演示网格。测试和优化此原型网格下的“战斗”条件下的“战斗”条件可为大型全球数据网格的开发提供适用于未来的大型全球数据网格的信息。
