Allocations

University Community | Wyoming-NCAR Alliance | NCAR Community

The Computational and Information Systems Laboratory (CISL) provides large-scale computing resources for university researchers and NCAR scientists in the atmospheric and related sciences. To access these supercomputers, storage systems, and other resources, users must apply for allocations via the processes defined for each community.

Applications are reviewed and time is allocated according to the needs of the projects and the availability of resources. Send questions about the following allocation opportunities to alloc@ucar.edu.

Derecho allocations

Allocations for use of the Derecho system will be made in the spring of 2022 rather than fall of 2021, as noted in the Daily Bulletin. The schedule for submitting Accelerated Scientific Discovery (ASD) project proposals has not changed. See NCAR lab ASD proposals and university community ASD proposals for details.


University Community

NCAR provides computing resources to the university community for investigations that are beyond the scope of university computing centers. The CISL HPC Advisory Panel (CHAP) accepts requests for large allocations of NCAR resources every six months, in March and September.

See University allocations for details.


Wyoming-NCAR Alliance

The NCAR-Wyoming Supercomputing Center represents a collaboration between NCAR and the University of Wyoming. As part of the Wyoming-NCAR Alliance (WNA), a portion of the Cheyenne system – about 160 million core-hours per year – is reserved for Wyoming-led projects and allocated by a University of Wyoming-managed process.

See the University of Wyoming site for details.


NCAR Community

NCAR investigators have access to CISL resources through allocations to the NCAR labs and have opportunities to submit requests for larger-scale, project-oriented allocations. Proposals for larger-scale projects are reviewed twice per year to become NCAR Strategic Capability projects.

See NCAR allocations for details.
