The stated goal of distributed Grid Computing is to create a network of interconnected computers that can act as one. This proposal for the "Open Science Grid" (OSG) is a component of a U.S. effort to create a truly seamless system where scientists and students distributed nationwide and worldwide can effectively collaborate. Physicists' demand for computing power is being spurred by the flood of data that will pour out of the Large Hadron Collider (LHC), the next-generation particle collider at CERN, the European particle physics laboratory near Geneva, as well as LIGO, the Laser Interferometer Gravitational-Wave Observatory in the U.S. These projects will produce dozens of petabytes (millions of billions of bytes) of data a year, or the equivalent of millions of DVDs, which physicists will store and sift through for at least a couple of decades in search of new phenomena. To put this in perspective, current estimates of the annual production of information on the planet are on the order of a few thousand petabytes, so these projects will be producing nearly 1% of that total. Some 100,000's of today's fastest personal computers "with accompanying tape and disk storage and high-speed networking equipment "will be needed to work together to analyse all of this data. A goal of the OSG is to enable dozens of other projects in other sciences to reap the benefits of Grid Computing

分布式网格计算的既定目标是创建一个可以作为一个整体运行的互连计算机网络。 “开放科学网格”（OSG）的提议是美国努力创建一个真正无缝的系统的一个组成部分，在这个系统中，分布在全国和世界各地的科学家和学生可以有效地合作。 大型强子对撞机（LHC）、欧洲核子研究中心（CERN）的下一代粒子对撞机、日内瓦附近的欧洲粒子物理实验室以及美国的激光干涉引力波天文台（LIGO）将产生大量数据，这刺激了物理学家对计算能力的需求。这些项目将产生数十PB的数据（数百亿字节）的数据，或相当于数百万张DVD，物理学家将存储和筛选这些数据至少几十年，以寻找新现象。 从这个角度来看，目前估计地球上每年产生的信息量约为几千PB，因此这些项目将产生近1%的总量。 需要大约10万台当今最快的个人电脑“附带磁带和磁盘存储以及高速网络设备”来共同分析所有这些数据。OSG的一个目标是使其他科学领域的许多其他项目也能从网格计算中获益
