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

加州理工高能物理(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年超级计算大会(SC09)。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，以支持美国大型强子对撞机计划和由NSF资助的其他主要计划。大型强子对撞机上最大的两个物理合作项目，CMS和ATLAS，每个都包括来自170所大学和实验室的2000多名物理学家和工程师，即将开始新一轮的高能前沿探索，在我们理解物质和时空的性质以及寻找新粒子方面开辟新的天地，当大型强子对撞机加速器和他们的实验明年春天恢复运行时。为了充分开发科学发现的潜力，实验产生的数据将使用位于世界各地的实验室和大学的150个计算和存储设施组成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，位于世界各地的个人物理学家和小团队重复访问，有时还会按需提取和传输数万亿字节的数据集，以便从已经了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的罕见“信号”。这些数据在大型强子对撞机运行的最初几年将达到数十拍字节，在接下来的十年内上升到艾字节范围。HEP团队希望在SC09上的演示将为更有效地分发和使用大型强子对撞机数据的发现铺平道路。除了使大型强子对撞机和其他数据密集型科学项目受益外，破纪录的结果还有助于将世界的注意力集中在HEP在发展网络基础设施、数据传输应用和全球系统监控以及全球合作(例如加州理工学院的EVO系统)方面的主要作用，并可能对研究、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.
