NCAR Accepting Requests for Large-Scale HPC Requests

The Computational and Information Systems Laboratory (CISL) at NCAR is now accepting requests from university-based researchers for large-scale allocation requests for the new 5.34-petaflops Cheyenne cluster; submissions are due March 20. The spring opportunity encompasses both university requests for large allocations and Climate Simulation Laboratory (CSL) requests.


NCAR allocations are open to US-based researchers supported by a National Science Foundation (NSF) award and who are pursuing objectives in the atmospheric, climate, and related sciences. See the "CISL allocations page": for eligibility details.


The CSL ensures that computing time is available for researchers with extremely demanding, high-profile climate simulations. Typically these require 10 million core-hours or more per year, perhaps for several years, and may produce many terabytes of model output that must be stored for analysis and comparison with other simulations and with observations. See the "CSL web page": for details.


Large allocations on Cheyenne are those requesting more than 400,000 core-hours. CISL accepts requests from university researchers for these large-scale allocations every six months. For submission instructions and information regarding available resources, see the "CISL HPC Allocations Panel (CHAP)": page.


Please contact if you have any questions about these two opportunities or need help determining which may be a better fit for your planned computational work.
