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.

该项目将通过Web Portal界面提供信息理论，通信理论和无线网络基础知识领域的研究人员。 Web服务将能够快速执行计算要求的计算机模拟，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对于该领域的进展至关重要，但是相关的计算要求通常超过除了最大机构以外的所有机构的可用资源。现存的网格为该计划提供动力，利用参与计算机的闲置能力。它没有部署专门的基础设施，而是在图书馆，学生实验室和参与机构的员工办公室中使用现有计算机和其他参与机构的办公室，这些机构选择捐赠空闲资源。该软件是在网格上运行的软件，该软件是由基于MATLAB的广泛的基于MATLAB的图书馆开发的，由主要的主要研究员开发，并由现有的400多个科学家和工程师的现有基础使用。为了简化用户体验并消除用户购买MATLAB许可证的需求，将开发Web门户接口。来自其他机构的研究人员将获得该服务的访问权限，并鼓励将自己的闲置计算机容量捐赠给主动性。IntellectualFure：在该网格将高度数学的领域研究中的研究。潜在的数学通常涉及多维积分，只能通过蒙特卡洛集成或模拟来解决。示例包括设计有效误差校正代码的设计，调制约束下的通道容量的计算以及无线临时网络协议的设计和分析。拟议的Web服务背后的基于网格的基础架构将允许快速平行执行Monte Carlo模拟。结果是，研究人员将比在单个处理器上运行时获得的结果更快（按数量级）。 他们的结果也将受益于他们的工作和基础架构主持的合作。Broader的影响：研究和教育更广泛的影响。研究的影响是，拟议的基于Web的仿真服务和基于网格的基础架构将为可能无法访问的团体提供世界一流的计算能力。拟议的帐户创建和管理政策将允许代表性不足或处于不利地位的团体或机构拥有更大的计算资源份额。 通过继续在开源许可下发布基础软件，并在会议上介绍有关软件和基础架构的教程，可以实现两种显着的传播形式。
