Travel to the SuperComputing 2009 Conference (SC09); November 2009; Portland, Oregon

加州理工学院高能物理（HEP）小组获得补充资金，以部分支持HEP团队参加在俄勒冈州波特兰举行的2009年超级计算会议（SC 09）。申请的资金将部分支持加州理工学院的五名关键团队成员参加会议，并继续展示和开发最先进的网络以及用于数据分发和分析的工具和服务，以支持美国LHC计划和NSF资助的其他主要计划。大型强子对撞机的两个最大的物理合作项目CMS和ATLAS，每个项目都包括来自170所大学和实验室的2,000多名物理学家和工程师，即将在高能前沿展开新一轮的探索，在我们理解物质和时空的本质以及寻找新粒子方面开辟新的天地，明年春天大型强子对撞机加速器和他们的实验恢复运行时。为了充分利用科学发现的潜力，实验产生的数据将使用位于世界各地实验室和大学的150个计算和存储设施的全球网格进行处理，分发和分析。 发现的关键是分析阶段，在这个阶段，位于世界各地的单个物理学家和小团体反复访问，有时根据需要提取和传输多TB的数据集，以便从已经理解的粒子相互作用的潜在压倒性“背景”中最佳地选择新物理学的罕见“信号”。这些数据在LHC运行的最初几年将达到数十PB，在未来十年内将上升到EB范围。HEP团队希望SC 09的演示将为更有效地分配和使用大量LHC数据的发现铺平道路。 除了有利于大型强子对撞机和其他数据密集型科学计划外，破纪录的结果还有助于将世界的注意力集中在HEP在网络基础设施发展中的主要作用，以及数据传输和全球系统监控的应用，以及全球合作（例如加州理工学院的EVO系统），对研究、教育和我们日常生活中的信息处理产生广泛的变革性影响。

The Caltech High Energy Physics (HEP) group is awarded supplemental funds to partly support the HEP team's participation in SuperComputing 2009 Conference (SC09) in Portland, Oregon. The requested funds will partially support the five key team members from Caltech to participate in the conference, and continue its demonstrations and development of state of the art networking as well as tools and services used for data distribution and analysis in support of the US LHC program and other major programs funded by the NSF. The two largest physics collaborations at the LHC, CMS and ATLAS, each encompassing more than 2,000 physicists and engineers from 170 universities and laboratories, are about to embark on a new round of exploration at the frontier of high energies, breaking new ground in our understanding the nature of matter and space-time and searching for new particles, when the LHC accelerator and their experiments resume operation next Spring. In order to fully exploit the potential for scientific discoveries, the data produced by the experiments will be processed, distributed, and analyzed using a global grid of 150 computing and storage facilities located at laboratories and universities around the world. The key to discovery is the analysis phase, where individual physicists and small groups located at sites around the world repeatedly access, and sometimes extract and transport multi-terabyte data sets on demand, in order to optimally select the rare "signals" of new physics from potentially overwhelming "backgrounds" from already-understood particle interactions. These data will amount to many tens of Petabytes in the early years of LHC operation, rising to the Exabyte range within the coming decade. The HEP team hopes that the demonstrations at SC09 will pave the way towards more effective distribution and use for discoveries of the masses of LHC data. In addition to benefiting the LHC and other programs in data intensive science, the record- breaking results have help focused the world's attention on the primary role of HEP in the development of cyberinfrastructure, and applications for data transport and worldwide systems monitoring, as well as worldwide collaboration (for example Caltech's EVO system) with the potential of a broad transformative impact on research, education and on our handling of information in our daily lives.
