This project will provide researchers in the fields of information theory, communication theory, and fundamentals of wireless networking with a grid-powered web service via a web portal interface. The web service will enable rapid execution of computationally demanding computer simulations that support the research of those working in the field. It is necessary because compute-intensive simulations are essential to progress in the field, yet the associated computational requirements often exceed the available resources of all but the largest institutions. The extant grid supplying power to the initiative leverages the idle capacity of participating computers. Rather than deploying a dedicated infrastructure, it uses existing computers in the libraries, student labs, and staff offices of the participating institution and other participating institutions that choose to donate idle resources.The software to be run on the grid leverages an extensive free Matlab-based library developed by the Principal Investigator and used by an existing base of over 400 scientists and engineers. To simplify the user experience and obviate the need for users to purchase Matlab licenses, a web portal interface will be developed. Researchers from other institutions will be given access to the service and will be encouraged to donate their own idle computer capacity to the initiative.Intellectual Merit: Research in the fields which this grid will serve highly mathematical. The underlying mathematics often involves multidimensional integrals that can only be solved via Monte Carlo integration or simulation. Examples include the design of efficient error correction codes, the calculation of channel capacity under modulation constraints, and the design and analysis of wireless ad hoc networking protocols. The grid-based infrastructure that lies behind the proposed web service will allow rapid parallel execution of Monte Carlo simulations. The consequence is that researchers will obtain results faster (by orders of magnitude) than could be obtained when running on a single processor. Their results will also benefit from dedicated tools for their work and the collaborations hosted by the infrastructure.Broader Impacts: There are both research and educational broader impacts. The research impact is that the proposed web-based simulation service and underlying grid-based infrastructure will provide world-class computing power to groups that might not otherwise have access. The proposed account creation and management policies will allow for underrepresented or disadvantaged groups or institutions to have a larger share of computing resources. Two notable forms of dissemination will be accomplished by continuing to publish the underlying software under an open source license and by presenting tutorials on the software and the infrastructure at conferences.

这个项目将提供研究人员在信息理论，通信理论和无线网络的基础领域与网格供电的Web服务通过Web门户接口。该网络服务将能够快速执行对计算要求很高的计算机模拟，以支持该领域工作人员的研究。这是必要的，因为计算密集型模拟是在该领域取得进展的关键，但相关的计算需求往往超过了所有最大的机构，但可用的资源。现存的电网为该计划提供电力，利用了参与计算机的空闲容量。它没有部署专用的基础设施，而是使用参与机构和其他选择捐赠闲置资源的参与机构的图书馆，学生实验室和工作人员办公室的现有计算机。将在网格上运行的软件利用了由首席研究员开发的广泛的免费Matlab库，并由现有的400多名科学家和工程师使用。为了简化用户体验并消除用户购买Matlab许可证的需要，将开发一个门户网站界面。其他机构的研究人员也可以使用这项服务，并鼓励他们将自己闲置的计算机容量捐赠给该计划。智力优势：在该网格将服务于高度数学的领域进行研究。基础数学通常涉及只能通过蒙特卡洛积分或模拟来解决的多维积分。例子包括有效的纠错码的设计，调制约束下的信道容量的计算，以及无线ad hoc网络协议的设计和分析。基于网格的基础设施，建议的Web服务将允许快速并行执行蒙特卡洛模拟。结果是，研究人员将比在单个处理器上运行时更快地获得结果（数量级）。 他们的成果也将受益于他们的工作专用工具和基础设施托管的协作。更广泛的影响：研究和教育都有更广泛的影响。研究的影响是，拟议的基于Web的模拟服务和基于网格的基础设施将提供世界一流的计算能力，否则可能无法访问的组。拟议的账户创建和管理政策将使代表性不足或处境不利的群体或机构能够拥有更大份额的计算资源。 两种值得注意的传播形式将通过继续根据开放源码许可证出版基本软件和在会议上介绍关于软件和基础设施的教程来实现。
