Managers, system administrators, user support staff, computational scientists, students, and educators are invited to contribute to discussions on the operation and use of campus and national advanced research computing centers at the 2017 Practice and Experience in Advanced Research Computing conference (PEARC17), which will be held in New Orleans, July 9-13, 2017. With the backing of more than a dozen community organizations, PEARC17 provides a forum for community-wide discussions of research computing’s challenges, opportunities, and solutions. Submissions aligned with the conference theme of Sustainability, Success, and Impact are particularly encouraged. The theme reflects key objectives for the advanced research computing community—sustainability of the infrastructure environment, measuring and ensuring success for organizations that provide and use advanced research computing, and impact of these technologies on the workforce, on science, and on scholarship.
