HPE has made a container image of its Cray Programming Environment (CPE) available to help users prepare for the 2022 delivery of the new Derecho supercomputer.
Cheyenne and Casper users can launch CPE by running the crayenv
command from either system's login nodes, then build and run applications within the containerized environment as described in this new CISL documentation
. To build large applications such as CESM and WRF, users should first secure a batch node using qinteractive
on Cheyenne or execcasper
on Casper, and then execute crayenv
HPE will ask users to provide feedback in return for their use of the container the vendor is providing. Users who need assistance are asked to contact CISL through the NCAR Research Computing help desk
