NMI: Designing and Building a National Middleware Infrastructure (NMI-2)

2001年，网格研究、集成、开发和支持中心（Grid Research, Integration, Development and Support, Grid）成立，用于定义、开发、部署和支持一个集成的国家中间件基础设施。该提案试图将这项工作扩展到(1)扩大所交付中间件的范围和功能；(2)拥抱和扩展新兴的开放网格服务体系结构（OGSA）标准；(3)扩大支持的社区范围；(4)在中间件领域建立国际共识。与GC1一样，网格中心2 （GC2）将严重依赖于开放协议和开源实现，并将与美国主要项目密切合作，包括NSF高级计算基础设施伙伴关系（PACI）、国家大气研究中心（NCAR）、匹兹堡超级计算机中心（PSC）和Internet2，以接触其他用户社区，并解决与校园基础设施的集成问题。该提案详细阐述了一项战略，以牢固的企业关系为基础，积极将相关技术转化为标准和行业。该建议强调NMI体系结构的定义以及将现有的中间件解决方案集成到该体系结构中。该提案的具体目标是：*定义一个可扩展的健壮的中间件体系结构，利用基于标准的开放网格服务体系结构。*创建机制和基础设施，将来自各种来源的中间件组件组合成集成的、可支持的中间件软件，每年至少发布两次。*根据NMI用户群体的需求，创建集成的基于ogsa的服务包，在数据、计算管理和远程测量等领域提供重点功能。这些软件包将集成来自许多NMI开发小组的软件。在美国国家科学基金会评审标准方面，我们的建议具有重要的理论意义和广泛的社会效益。网格的领导和员工在设计和部署中间件方面已经建立了声誉。这些研发活动对研究、教育和其他方面都有实际的、直接的影响。网格的影响已经相当大，IBM、Hewlett-Packard和Oracle等十多家公司都致力于基于网格技术构建产品。GC2将更加强调这些扩展工作，以网格领导推动的新兴OGSA标准为中心。

In 2001, the Grid Research, Integration, Development and Support (GRIDS) Center was established to define, develop, deploy, and support an integrated national middleware infrastructure. This proposal seeks to extend this work to (1) broaden the scope and capabilities of the middleware delivered; (2) embrace and extend emerging Open Grid Services Architecture (OGSA) standards; (3) expand the range of communities supported; and (4) establish international consensus in middleware. GRIDS Center 2 (GC2), like GC1, will rely heavily on open protocols, and open source implementations, and will work closely with major U.S. projects including the NSF Partnerships for Advanced Computational Infrastructure (PACI), the National Center for Atmospheric Research (NCAR), the Pittsburgh Supercomputer Center (PSC), and Internet2 to reach out to other user communities and to address integration with campus infrastructures. The proposal details a strategy to aggressively transition relevant technologies to standardsand industry, building on strong corporate relationships.This proposal stresses the definition of the NMI architecture and the integration of extant middleware solutions into this architecture. Specific goals of this proposal are to:* define a scalable robust middleware architecture leveraging the standards-based Open Grid Services Architecture.* create mechanisms and infrastructure for combining middleware components from a range of sources into integrated, supportable middleware software releases at least twice a year.* based on requirements of the NMI user communities, create integrated OGSA-based services packages that provide focused functionality in areas such as data, computation management, and teleinstrumentation. These packages will integrate software from many NMI development groups.Regarding NSF merit review criteria, our proposal has intellectual significance and broad benefits for society. GRIDS leadership and staff have established reputations in designing and deploying middleware. These R&D activities have real, immediate implications in the research, education and beyond. GRIDS impact has already been considerable, with over a dozen companies such as IBM, Hewlett-Packard, and Oracle committed to building products on GRIDS technology. GC2 will see even greater emphasis on theseoutreach efforts, centering on emergent OGSA standards that are being driven by the GRIDS leadership..
