Pacific Rim Application and Grid Middleware: Broadening PRAGMA Impact on Global Science and Technology Communities

摘要-OCI 0627026数据、软件和中间结果的例行共享正在成为国际研究团队转向协作团队科学的一种基本模式。下一代技术用于控制仪器、检查远程存储的大型3D数据集、支持高分辨率视频会议以及实时整合全球资源，已在超级计算和IGRID等会议上展示。然而，技术、文化、语言因素和不同的共享信息的方法，使全球协作和这些技术的日常使用对许多人来说是遥不可及的。成立于2002年的环太平洋应用程序和网格中间件组装[PRAGMA]是一个开放的组织，其重点是如何切实地创建、支持和维持国际科学和技术合作。假设进行具体的实验，确定支持这些实验的候选技术和人员，在我们的跨太平洋常规使用实验室进行评估，并将成功的解决方案集成到特定国家的软件堆栈或GGF标准中。该组织利用来自25个机构的100多名个人的聪明才智来创建和维持这些长期活动。PRAGMA作为专业互动、思想、信息和网格技术的国际渠道，发挥着至关重要的作用。由于我们对新思想持开放态度的文化，我们多方面的合作框架催化并促成了新的活动。他们的务实方法带来了新的科学见解，增强了技术]，并从根本上分享了经验，这些经验体现在他们的常规实验室中。尽管私人投资者和其他人取得了重大进展，但网格(或网络基础设施)在常规基础上仍然很繁琐。底层的GLUE软件变化很快，生产网格之间的可移植性和/或互操作性很少，从文化上讲，人们仍在试图理解从“独立工作”到“协作工作”的巨大变化。它们在普拉格玛发挥的作用在提供足够的人员和组织结构以取得进展方面起到了催化作用。P.I.建议继续发挥这一作用，并将其影响扩展到新的应用领域，在他们的常规使用实验室中更加重视数据，利用Lambda网格的潜力，与生产网格合作以实现互操作，并更广泛地参与环太平洋地区的中间件开发，重点放在以下四个关键领域：1.在特定应用领域发展新的和深化现有的合作，以专注于他们的网格开发并产生新的科学见解；2.加强和扩大我们的常规使用应用网格实验室，允许测试、改进中间件和应用代码，并将经验教训推广给其他人；3.改进多途径软件传播途径，确保软件和中间件在整个网格社区中的访问和使用，并促进标准；4.加强和扩大环太平洋地区网格用户和开发人员社区，以扩大其对太平洋地区内外新群体和努力的影响和互动。拟议的活动将导致在更广泛但有针对性的科学领域取得进展；加强网格运营中心和常规使用实验室；改进基本的中间件；与lambda网格互操作；建立国家大型资源之间的联系；将更坚实的国际中间件整合到NMI和其他中间件框架中。这项工作的影响将是加强和扩大合作的渠道和框架，以帮助确保国际电网工作的兼容性；将美国的战略性研究投资(例如，OptIPuter、Geon、NMI、TeraGrid、LTER)扩展到其他机构，为新的研究和教育活动建立框架，并将环太平洋地区和全球合作伙伴的见解/软件纳入美国和其他全球活动。随着我们继续学习和传播我们关于如何使电网在日常基础上可用的发现，科学和科学家将大大受益。

Abstract - OCI 0627026Routine sharing of data, software, and intermediate findings is becoming an essential mode forinternational research teams as they move to Collaborative Team Science. The next generation oftechnology for controlling instruments, examining remotely-stored large 3D data sets, enabling high resolution video conferencing, and integrating global resources in real time has been demonstrated at meetings such as Supercomputing and iGRID. Yet, technological, cultural, language factors and disparate methods for sharing information, keep global collaboration and daily use of these technologies out of reach for many Established in 2002, the Pacific Rim Application and Grid Middleware Assembly [PRAGMA] is an open organization whose focus is how to practically create, support, and sustain international science and technology collaborations. Specific experiments are postulated, candidate technologies and people are identified to support these experiments, evaluation is performed in our trans-Pacific routine-use laboratory, and successful solutions are integrated into country-specific software stacks or GGF standards. The group harnesses the ingenuity of more than 100 individuals from 25 institutions to create and sustain these long-term activities. PRAGMA plays a critical role as an international conduit for professional interactions, ideas, information, and grid technology. Our multi-faceted framework for collaboration catalyses and enables new activities because of a culture of openness to new ideas. Their pragmatic approach has led to new scientific insights, enhanced technology] and a fundamental sharing of experiences manifest in their routine-use laboratory.While the P.I.s and others have made significant progress, the grid (or cyberinfrastructure) remains cumbersome on a routine basis. Underlying glue software changes rapidly, portability and/or interoperability among production grids are rare, and culturally, people are still trying to understand the sea change from "work independently" to "work collaboratively." Their role in PRAGMA has been catalytic in terms of providing enough people and organizational structure to enable progress. The P.I.s propose to continue this role and expand their impact to new application areas, increasing emphasis on data in their routine use laboratory, harness the potential of lambda grids, work with productions grids to achieve interoperations, and broader involvement of middleware developments from outside the Pacific Rim, with focus on the following four key areas:1. Develop new and deepen existing collaborations in specific application areas to focus their grid developments and to produce new scientific insight;2. Enhance and expand our routine use application grid laboratory to allow for middleware andapplications codes to be tested, improved, and lessons learned to be advanced to others;3. Improve multi-way software dissemination pathways, to ensure access and use of software and middleware throughout the grid community and to promote standards;4. Strengthen and expand the Pacific Rim community of grid users and developers to broaden its impact on and interactions with new groups and efforts in and beyond the Pacific Rim.The proposed activities will lead to advances in a broader yet targeted set of scientific areas; strengthen the grid operations center and the routine use laboratory; improve essentialmiddleware; interoperate with the lambda grids; create ties between large national resources; integrate more solid international middleware into the NMI and other middleware frameworks. The impact of the work will be in the strengthening and expanding the conduit and framework for collaboration to help ensure compatibility of international grid efforts; extending strategic US research investments (e.g. .OptIPuter, GEON, NMI, Teragrid, LTER) to other institutions, building a framework for new research and education activities, and incorporating insights/software from Pacific Rim and global partners into US and other global activities. As we continue to learn and disseminate our findings on how to make the grid usable on a routine basis, science and scientists will greatly benefit.
