Frameworks: Software NSCI-Open OnDemand 2.0: Advancing Accessibility and Scalability for Computational Science through Leveraged Software Cyberinfrastructure

减少限制采用高性能计算(HPC)的障碍解决了一个广泛影响科学、工程和人文社区的重要问题。这一努力建立在拥有庞大而多样的用户社区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的基础上。这种方法有几个好处：-它增加了HPC资源的使用，这些社区尚未在HPC上得到很好的代表，但对HPC的需求不断增长。-通过支持用于监控和可视化系统状态的高级功能，也有利于高性能计算提供商。-产生的框架将用于培训和劳动力发展，扩大未来为Science使用先进网络基础设施的能力。该项目建立在现有努力的优势基础上，并有可能造福于广泛的用户社区。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系统的门槛。该项目结合了两个广泛使用的高性能计算资源：-Open OnDemand 1.0--用于访问高性能计算服务的现有开源、基于网络的项目；和-Open XDMoD--一个促进高性能计算资源管理的开源工具。项目活动包括增强现有的门户网站到高性能计算系统(OnDemand)，集成XDMoD，扩展门户以提供其他科学领域的访问方法，以及改进系统的可伸缩性。该软件采用独特的每用户Web服务器架构。这为用户提供了通过Web浏览器访问HPC群集的完全系统级访问权限。XDMoD提供工作绩效可见性，使用户能够更高效地使用HPC资源。创新和发现将通过一项研究相结合，该研究调查如何利用Open OnDemand提供的具有科学门户的系统级访问。综合平台将提高资源利用可见性，扩展到更多资源类型和机构，并通过直观的网络界面支持HPC资源的顺畅和轻松利用。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

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.
