U.S. university researchers who are supported by an NSF award can request an initial small allocation of up to 400,000 core-hours on Cheyenne. These allocations can be used to complete small projects or to conduct initial runs in preparation for submitting a request for a large allocation.

A graduate student, post-doctoral researcher, or new faculty member at a U.S. university can request a one-time allocation of up to 400,000 Cheyenne core-hours. These awards typically support dissertations, help foster early career research, or provide seed resources for pursuing funded research. An individual can request a new exploratory project at each stage of their career path. A new faculty member is any eligible researcher who has not previously had an NCAR allocation as a faculty member.

Earth system scientists can request access to NCAR’s Casper data analysis cluster and the Campaign Storage file system to allow them to conduct analyses on data sets curated by NCAR data services and accessible via our storage systems. We are pleased to make Data Analysis Project allocations available to researchers from any eligible institution regardless of the source of funding for the planned analysis. Researchers are only required to identify the specific NCAR-hosted data sets that are essential to completing their science objectives. Because of this expanded eligibility, Data Analysis Projects cannot make use of Cheyenne.

Researchers interested only in access to NCAR-hosted data – that is, using NCAR's data-access nodes to perform file-management operations – can submit Data Analysis project requests for such access. However, researchers are also encouraged to make use of the Casper system for data analysis to minimize their need to move large amounts of data to their home institutions.

CISL offers opportunities to undergraduate and graduate faculty and instructors at U.S. 2- and 4-year institutions to use NCAR HPC and analysis resources in their courses in Earth system science and related areas. “Special projects” or honors thesis courses under the guidance of a faculty member are eligible.

This opportunity is for NCAR scientists only, University requests use the form below. For information on completing this form see NSC Requests These NSC allocations should target large-scale projects lasting one year or to the end of Cheyenne that align with NCAR’s scientific priorities and strategic plans
