SDCI NMI Improvement: Open Grid Computing Environments Software for Science Gateways

国家科学基金会NSF数字基础设施软件开发(SDCI)计划数字基础设施办公室建议编号：0721656主要调查者：Marlon Pierce研究所：印第安纳大学建议标题：SDCI NMI改进：科学网关的开放网格计算环境软件摘要开放网格计算环境(OGCE)项目将开发、集成、打包和分发软件到TeraGrid科学网关和相关的科学门户网站。科学门户支持科学研究社区及其外展工作。它们由基于Web的用户和应用程序编程接口组成，这些接口提供对网络基础设施中间件的高级访问，并将中间件功能转换为科学用例。OGCE致力于为这些网关开发团队提供他们所需的可重用软件。OGCE门户软件和组件库目前为许多网格中间件工具提供客户端支持，包括Globus工具包、秃鹰、MyProxy和GPIR信息服务。门户软件是打包的，易于安装，允许门户开发人员在单个步骤中构建一个正常运行的网格门户。目前的资金奖励将扩展这项工作，以提供几个额外的功能以及维护当前的软件套件。以前版本的OGCE集中于客户端组件，用于通过通用的高级网格编程接口进行远程作业和文件管理。在项目扩展中，OGCE将以此为基础，通过以下工具满足科学家和网关供应商的信息和元数据管理需求：个人和资源元数据目录；增强的系统信息工具，包括访问批处理队列预测服务；以及网关审计、会计和记录库。OGCE还将为向网关添加科学应用程序提供改进的支持。这里的工作将包括为最终用户提供的工作流引擎的计算实验构建器接口、为应用程序提供商提供的应用程序工厂服务，以及为门户开发人员提供的portlet XML标记库。最后，OGCE确定了Web2.0？这些方法对门户建设进程具有潜在的革命性意义，并将在门户社区内引领这些发展。

National Science FoundationNSF Software Development for Cyberinfrastructure (SDCI) ProgramOffice of CyberinfrastructureProposal Number: 0721656Principal Investigator: Marlon PierceInstitution: Indiana UniversityProposal Title: SDCI NMI Improvement: Open Grid Computing Environments Software for Science Gateways Abstract The Open Grid Computing Environments (OGCE) project will develop, integrate, package, and distribute software to TeraGrid science gateways and related science portal efforts. Science gateways support scientific research communities and their outreach efforts. They consist of Web-based user and application programming interfaces that provide high-level access to Cyberinfrastructure middleware and translate middleware capabilities into scientific use cases. The OGCE works to provide these gateway development groups with the reusable software they need. OGCE portal software and component libraries currently provide client support for numerous Grid middleware tools, including the Globus Toolkit, Condor, MyProxy, and GPIR information services. The portal software is packaged and easily installable, allowing portal developers to build a functioning Grid portal in a single step. The current funding award will extend this work to provide several additional features as well as maintenance of the current software suite. Previous versions of the OGCE releases concentrated on client components for remote job and file management through a common, high-level Grid programming interface. In the project extension, the OGCE will build on this to address the information and metadata management needs of both scientists and gateway providers with the following tools: personal and resource metadata catalogs; enhanced system information tools, including access to batch queue prediction services; and gateway auditing, accounting, and logging libraries. The OGCE will also provide improved support for adding science applications to gateways. Efforts here will include computational experiment builder interfaces to workflow engines for end users, application factory services for application providers, and portlet XML tag libraries for portal developers. Finally, the OGCE identifies ?Web 2.0? approaches as potentially revolutionary to the gateway building process and will lead these developments within the gateway community.
