CRI: CRD: A Web-Accessible Grid-Computing Resource for the Telecommunications Research Community

这个项目将为信息论、通信理论和无线网络基础领域的研究人员提供通过Web门户接口的网格供电的Web服务。网络服务将能够快速执行计算要求很高的计算机模拟，以支持那些在该领域工作的人的研究。这是必要的，因为计算密集型模拟对该领域的进展至关重要，但相关的计算要求往往超过除最大机构以外的所有机构的可用资源。为该倡议提供电力的现有电网利用了参与其中的计算机的闲置能力。它没有部署专用的基础设施，而是使用参与机构的图书馆、学生实验室和教职员工办公室以及其他选择捐赠闲置资源的参与机构的现有计算机。在网格上运行的软件利用由首席调查员开发的、由400多名科学家和工程师组成的现有基础设施所使用的基于MatLab的广泛免费库。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。来自其他机构的研究人员将被允许使用这项服务，并将被鼓励将他们自己的闲置计算机容量捐赠给该倡议。智力优势：在这个网格将服务于高度数学的领域进行研究。基本的数学通常涉及多维积分，这些积分只能通过蒙特卡罗积分或模拟来求解。例子包括有效纠错码的设计、调制约束下的信道容量的计算以及无线自组网协议的设计和分析。建议的Web服务背后的基于网格的基础设施将允许快速并行执行蒙特卡罗模拟。其结果是，研究人员将比在单处理器上运行时更快地(按数量级)获得结果。他们的成果还将受益于他们工作的专用工具和基础设施托管的合作。广泛的影响：既有研究的影响，也有更广泛的教育影响。研究的影响是，拟议的基于网络的模拟服务和基于网格的基础设施将为原本可能无法访问的团体提供世界级的计算能力。拟议的账户创建和管理政策将允许任职人数不足或处境不利的群体或机构拥有更大份额的计算资源。将通过继续在开放源码许可证下发布基础软件和在会议上介绍软件和基础设施的教程来实现两种值得注意的传播形式。

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.
