CAM/CESM on Grace Hopper

Here we present a docker container that runs on arm processors?

This Docker Container is a Faberge Egg

Build

Base CESM

Base CESM provides the following packages installed from source code by the maintainers:

• Fortran-9.5
• MPI
• BLAS
• LAPACK
• HDF5 (with parallel support)
• NetCDF-C
• NetCDF-Fortran
• Parrallel IO (no fortran)

We also install python-3.8 to manage CESM's ...

How to build:

1. Install docker
2. Navigate to ./cesm_base
3. Run ./build.sh. This might take awhile, but should build the container cesm_base

Note. This image should be good for a couple of years, may need to update as ubuntu depricates 24.04

CESM

This container installes CESM2.2.2 (We included CESM2.1.5 as well, but we were having trouble getting it to run, updates to follow).

To Build

1. Build cesm_base image
2. Navigate to ./cesm
3. Runn ./build.sh to build the container. This will pull CESM things and takes awhile

x86

While not supported by this repo, the only hard coded aarch64 package is the miniconde install script. Probably could replace with Linux-x86 to build. Untested though.
