CISL HPC Allocations Panel

Created by Dave Hart, last modified on 2023-11-03

CISL's advisory panel on high-performance computing and services is the CISL HPC Allocations Panel (CHAP). The CHAP's primary responsibility is to assess the merit of large computing requests for CISL supercomputers and related resources.

The panel accepts computing proposals from U.S. university researchers in Earth system science and related activities who are supported by the National Science Foundation (NSF). The CHAP recommends action with respect to a prospective project request on the basis of the computational experimental design, computational effectiveness, and availability of computing resources.


The next university deadline for submitting Large Allocation Requests is March 12, 2024.


CHAP members, most of whom are from the university community, are appointed to three-year terms by the CISL Director. Meetings are scheduled twice a year, usually in April and October. NSF's program coordinator for the NCAR and Facilities Section attends the semi-annual meetings and provides guidance from the NSF.
