NMI: Instruments and Sensors as Network Services: Instruments as First Class Members of the Grid

该方案研究了一种通用仪器中间件体系结构(CIMA)，以提高仪器的可访问性，促进仪器与网格的集成。建议的中间件将基于当前的网格实现标准，并可通过开放网格服务体系结构(OGSA)和公共组件体系结构(CCA)等平台无关的标准访问。重点将放在支持各种仪器和控制器类型上，包括创建可用于微型无线控制器的小型实施，如Berkeley Mote传感器包以及基于嵌入式PC-104和VME的控制器系统。建议的CIMA实施将在代表一系列共享仪器应用的三个环境中进行评估：同步加速器源的X射线结晶学、使用嵌入式监视器实时获取网络性能数据，以及使用Berkeley Mote无线传感器的小型传感器网络节点。最终产品将是一个一致的和可重复使用的框架，用于将共享的仪器资源包括在地理分布的网格中。影响广泛，具有智力优势。这项拟议的工作将对许多仪器驱动的网格计算项目的发展产生重要影响，进而对许多科学教育项目产生重要影响。为联网仪器和国际e-Science合作制定工业标准，以及开发和评估新的普适计算方法，还有进一步的影响。联合PI积极参与全球网格论坛、美国能源部CCA论坛和其他网格和HPC标准工作，并将与工业和国防部项目一起用于发展和公布拟议工作的结果。联合PI也有指导来自代表性不足群体的学生的记录，并有从K-12到博士后的所有级别的教育项目。

This proposal researches a Common Instrument Middleware Architecture (CIMA)to improve accessibility of instruments and to facilitate their integration into the Grid. The proposed middleware will be based on current Grid implementation standards and accessible through platform independent standards such as the Open Grid Services Architecture (OGSA) and the Common Component Architecture (CCA). Emphasis will be placed on supporting a variety of instrument and controller types including creating a small implementation that can be used with tiny wireless controllers such as the Berkeley Mote sensor package as well as embedded PC-104- and VME-based controller systems. The proposed CIMA implementation will be evaluated in three settings representing a spectrum of shared instrument applications: X-ray crystallography at a synchrotron source, real-time acquisition of network performance data with embedded monitors, and small sensor network nodes using Berkeley Mote wireless sensors. The end product will be a consistent and reusable framework for including shared instrument resources in geographically distributed Grids.Broad impact and intellectual merit. The proposed work will have important ramifications in the development of many instrument-driven Grid computing projects, and by extension, to many science education programs. Further implications exist for the development of industrial standards for networking instruments and international e-Science collaborations, as well as developing and evaluating new ubiquitous computing methodologies. The co-PI's are active in the Global Grid Forum, the DoE CCA Forum, and other Grid and HPC standards efforts, and together with industrial and DoD projects these will be used to evolve and promulgate the results of the proposed work. The co- PI's also have a track record of mentoring students from underrepresented groups, and have education projects at all levels from K-12 to postdoctoral.
