A new bug-fix release of E3SM-Unified is available: 1.9.3.  E3SM-Unified is a combination conda and spack environment that includes a large amount of analysis and pre- and post-processing software for E3SM users.  The new version includes updates to E3SM-Diags, e3sm_to_cmip, ILAMB, MPAS-Analysis, xcdat, and zstash packages.

Activation

As in previous versions, you can access the environment as usual by sourcing an activation script:

...

source /lus/grand/projects/E3SMinput/soft/e3sm-unified/load_latest_e3sm_unified_polaris.sh

Details

A few critical bugs were revealed after the release of 1.9.2 in January and these are fixed here. The new version has been deployed on most supported machines: Andes, Anvil, Chicoma, Chrysalis, Compy, Frontier, Perlmutter and ALCF Polaris (not to be confused with the E3SM Polaris software). It will be deployed on Acme1 later this week.

...

On 6 machines (Anvil, Chicoma, Chrysalis, Compy, Frontier and Perlmutter) there are 6 packages of interest -- ESMF, ILAMB, MOAB, NCO, TempestExtremes and TempestRemap -- that have been built with Spack using system compilers and MPI libraries.  When you load E3SM-Unified on a compute node, you will have access to these versions, which can be run in parallel and which will typically run more efficiently than their counterparts in conda packages.
