National Science FoundationNSF Software Development for Cyberinfrastructure (SDCI) ProgramOffice of CyberinfrastructureProposal Number: 0722019Principal Investigator: Ewa DeelmanInstitution: University of Southern CaliforniaProposal Title: SDCI NMI Improvement: Pegasus: From Concept to Execution --- Mapping Scientific Workflows onto the National Cyberinfrastructure Abstract This project addresses improvements to Pegasus, a workflow system overlaying a workflow engine called DAGMan. These improvements will make Pegasus easy to deploy and use across a broad range of science users and environments. New debug capabilities will be added, usability will be improved, new communities of users will be directly engaged, richer workflow representations will be supported, dynamic workflows will be supported, priority-based task submission capabilities will be added, monitoring will be enhanced, and integration with emerging workflow technologies will be pursued. Intellectual merit lies in the demonstrated value to physics, astronomy, and other users. Broad impact of this proposal includes extension of the user base across new communities, including those using TeraGrid and OSG.

国家科学基金会国家科学基金会数字基础设施(SDCI)软件开发计划办公室数字基础设施办公室建议编号：0722019主要调查者：Ewa Deelman研究所：南加州大学建议标题：SDCI NMI改进：飞马：从概念到执行-绘制国家数字基础设施上的科学工作流摘要该项目致力于改进Pegasus，一个覆盖了称为Dagman的工作流引擎的工作流系统。这些改进将使Pegasus易于在广泛的科学用户和环境中部署和使用。将增加新的调试能力，提高可用性，直接接触新的用户社区，支持更丰富的工作流表示，支持动态工作流，增加基于优先级的任务提交能力，加强监测，并寻求与新兴工作流技术的整合。智力的价值在于对物理学、天文学和其他用户的证明价值。这项提议的广泛影响包括将用户基础扩展到新的社区，包括使用TeraGrid和OSG的社区。
