Reducing barriers that limit the adoption of high performance computing (HPC) addresses an important problem that broadly affects the science, engineering, and humanities communities. This effort builds on existing capabilities with large and varied user communities, and on national scale cyberinfrastructure and high-performance computing resources. The approach has several benefits: - It increases the use of HPC resources among communities that are not well represented on HPC yet, but have growing needs for HPC. - It is also beneficial to HPC providers, by supporting advanced features for monitoring and visualization of the states of systems. - The resulting framework will be used for training and workforce development, expanding the future ability to use advanced cyberinfrastructure for science.This project builds on the strengths of existing efforts, and has the potential to benefit a broad user community. The project develops Open OnDemand 2.0, an open-source software that enables access to high-performance computing, cloud, and remote computing resources via the web, and lower the barriers to access HPC systems. The project combines two widely used HPC resources: - Open OnDemand 1.0 - an existing open-source, web-based project for accessing HPC services; and - Open XDMoD - an open-source tool that facilitates the management of high performance computing resources.Project activities include enhancing an existing web portal-to-HPC system (OnDemand), integrating XDMoD, extending the portal to provide other methods of access for other science domains, and improving the scaling of the system. The software employs a unique per-user web server architecture. This gives a user full system-level access to an HPC cluster through a web browser. Job performance visibility is provided by XDMoD, which enables users to make more efficient usage of HPC resources. Innovation and discovery will be integrated through a study which investigates ways to leverage the system-level access provided by Open OnDemand with science gateways. The integrated platform will enhance resource utilization visibility, extend to more resource types and institutions, and support a smooth and easy utilization of HPC resources with intuitive web interfaces.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

减少限制采用高性能计算（HPC）的障碍，解决了广泛影响科学，工程和人文社区的重要问题。 这一努力的基础是拥有大量不同用户群体的现有能力，以及国家规模的网络基础设施和高性能计算资源。 这种方法有几个好处：-它增加了HPC资源的使用，这些资源在HPC上还没有得到很好的代表，但对HPC的需求不断增长。 - 通过支持用于监视和可视化系统状态的高级功能，它也有利于HPC提供商。- 由此产生的框架将用于培训和劳动力发展，扩大未来利用先进网络基础设施促进科学的能力，该项目建立在现有努力的基础上，有可能使广大用户群体受益。该项目开发了Open OnDemand 2.0，这是一款开源软件，可以通过Web访问高性能计算、云和远程计算资源，并降低访问HPC系统的障碍。该项目结合了两个广泛使用的HPC资源：- Open OnDemand 1.0 -一个现有的开源，基于Web的项目，用于访问HPC服务; Open XDMoD --一个开源工具，可促进高性能计算资源的管理。项目活动包括增强现有的Web门户到HPC系统（OnDemand），集成XDMoD，扩展门户以提供其他科学领域的其他访问方法，并提高系统的可伸缩性。 该软件采用独特的每用户Web服务器架构。这使用户可以通过Web浏览器对HPC群集进行完全的系统级访问。 作业性能可见性由XDMoD提供，使用户能够更有效地使用HPC资源。创新和发现将通过一项研究来整合，该研究调查如何利用Open OnDemand提供的系统级访问与科学网关。 该集成平台将增强资源利用的可见性，扩展到更多资源类型和机构，并通过直观的网络界面支持顺利、轻松地利用HPC资源。该奖项反映了NSF的法定使命，并通过使用基金会的知识产权进行评估，被认为值得支持优点和更广泛的影响审查标准。
