Package Catalog

This page provides a complete inventory of packages included in the latest E3SM-Unified recipe (1.13.0rc1 at the time of this branch), along with the most important package constraints. The authoritative source is recipes/e3sm-unified/e3sm-unified-feedstock/recipe/recipe.yaml.

Notes

The exact environment depends on the selected package variant:

• nompi is the default conda-only variant.

• mpich and openmpi add MPI-enabled conda packages.

• hpc omits several system-library-heavy packages from the conda package so they can be provided by the HPC deployment through Spack.
