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

加州理工学院高能物理（HEP）小组获得了补充资金，以部分支持HEP小组参加在俄勒冈州波特兰举行的2009年超级计算会议（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项目和其他由美国国家科学基金会资助的主要项目。大型强子对撞机（LHC）的两个最大的物理合作项目CMS和ATLAS，每个项目都有来自170所大学和实验室的2000多名物理学家和工程师，当LHC加速器和它们的实验明年春天恢复运行时，它们即将开始新一轮的高能前沿探索，在我们对物质和时空本质的理解和寻找新粒子方面开辟新的领域。为了充分挖掘科学发现的潜力，实验产生的数据将通过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，世界各地的物理学家和小组反复访问，有时根据需要提取和传输数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的“背景”中最佳地选择新物理学的罕见“信号”。在大型强子对撞机运行的最初几年，这些数据将达到数十pb，在未来十年内上升到eb级。HEP团队希望SC09的演示将为更有效地分配和使用LHC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测的应用，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具有广泛变革影响的潜力。

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.
