CISL High-performance computing Allocations Panel (CHAP)

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 the atmospheric and closely related sciences who are supported by the National Science Foundation (NSF). The CHAP recommends action with respect to a prospective user's request on the basis of the computational experimental design, computational effectiveness, and availability of computing resources.

The next deadline for Large Allocation Requests is March 22.

Allocations for the new NCAR supercomputing system

Allocations for use of the new system that will become operational next year will be made in the fall of 2021. CISL will also solicit requests for Accelerated Scientific Discovery (ASD) projects in the fall.

 
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 May and October. NSF's program coordinator for the NCAR and Facilities Section attends the semi-annual meetings and provides guidance from the NSF.
