Application Closes at 11:59pm Mountain Time on: 2027-01-19 About the Role The Summer Internships in Parallel Computational Science (SIParCS) program at the NSF National Center for Atmospheric Research (NCAR) offers graduate students and undergraduates who have completed their sophomore year significant hands-on R&D opportunities in high-performance computing (HPC) and related fields that use HPC for scientific discovery and modeling. This program embeds students as summer interns in the Computational and Information Systems Laboratory (CISL), an organization within NSF NCAR charged with provisioning supercomputing and data systems to the geosciences research community, as well as conducting research and development in computational science, data analysis, scientific visualization and numerical modeling. These twin roles of service and research in CISL support NSF NCAR's broad scientific mission of discovery in the atmospheric and related sciences. The 2027 summer internships are 11 weeks in duration. Applicants must be available to work 40 hours per week from May 17, 2027 through July 30, 2027 for participation in the program. NSF NCAR has 3 unpaid holidays for interns during the summer internship (Memorial Day, Juneteenth, Independence Day). Program requirements, beyond working on projects, include attending appropriate technical seminars, attending skills-enhancing workshops, preparing a poster, and giving an oral presentation of results at the end of the summer. For Summer 2027, we are planning for an in-person internship program where interns come on-site to our Boulder, Colorado campuses and meetings may be held in person or hybridly over Zoom or Google Meet.
