For nearly four decades, the National Science Foundation (NSF) has played a leadership role in provisioning advanced cyberinfrastructure capabilities for the Nation's Science and Engineering (S&E) researchers. An important component in this investment is the leadership-class computing program that provides computational and data analytics capabilities at the largest scale to inspire transformative S&E discoveries that would not be possible otherwise. NSF's current leadership-class computing investment supports Frontera, the largest High-Performance Computing (HPC) system on a US academic campus. The Frontera system is deployed and operated by the Texas Advanced Computing Center (TACC) at the University of Texas (UT) at Austin. This travel grant will support the participation of researchers who have been awarded a computer time allocation on the Frontera system at a future Principal Investigator (PI) meeting organized by TACC. The award will also support travel for technical coordination between researchers and the Frontera project to ensure optimal and effective utilization of the Frontera system.The goal of the PI meeting is to allow Frontera research users, as well as their students, to share scientific results, exchange practical lessons-learned, and present their overall experience from using the Frontera system. In addition to research presentations, the meeting will have ample time, as well as facilitated sessions, to promote increased interaction between Frontera research users and project staff. The outcome of the PI meeting will not only enable the Frontera project to better understand and serve the scientific research community, but also build a community to better represent the unique needs of S&E research that require access to NSF leadership computing facilities. To facilitate deeper coordination beyond the PI meeting, this award will also provide travel support to enable technical coordination between the research user teams and the Frontera project.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.

近四十年来，国家科学基金会（NSF）在为国家科学与工程（S＆E）研究人员（S＆E）研究人员提供高级网络基础设施能力方面发挥了领导作用。这项投资的一个重要组成部分是领导级计算计划，该计划提供了最大规模的计算和数据分析功能，以激发不可能的变革性S＆E发现。 NSF当前的领导级计算投资支持Frontera，Frontera是美国学术校园中最大的高性能计算（HPC）系统。 Frontera系统由德克萨斯大学（TACC）的德克萨斯大学奥斯汀分校（TACC）部署和运营。该旅行赠款将支持在TACC组织的未来首席研究员（PI）会议上，在Frontera系统上授予计算机时间分配的研究人员的参与。该奖项还将支持研究人员和Frontera项目之间的技术协调旅行，以确保对Frontera系统的最佳和有效利用。PI会议的目标是允许Frontera Research用户及其学生分享科学成果，并分享科学成果交换实用的课程学习，并通过使用Frontera系统介绍他们的整体经验。除了研究演讲外，会议还将有足够的时间以及促进会议，以促进Frontera研究使用者与项目人员之间的互动增加。 PI会议的结果不仅将使Frontera项目能够更好地理解和服务科学研究界，而且还可以建立一个社区，以更好地代表需要访问NSF领导力计算设施的S＆E研究的独特需求。为了促进PI会议以外的更深入的协调，该奖项还将提供旅行支持，以实现研究用户团队与Frontera项目之间的技术协调。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子值得评估的支持的。和更广泛的影响审查标准。
