Dear E3SM Team,
A new version of E3SM-Unified is available: 1.8.0. E3SM-Unified is a combination conda and spack environment that includes a large amount of analysis software that is useful for E3SM users. The new version includes updates to E3SM-Diags, e3sm_to_cmip, MPAS-Analysis, MOAB, NCO, xcdat, zppy, zstash and many more packages.
New and improved in 1.8.0
E3SM Diags: … More updates can be found in the v2.8.0 Release Notes.
e3sm_to_cmip: … More updates can be found in the v1.9.0 Release Notes.
MPAS-Analysis: New features have been added from the recent E3SM hackathon on MPAS-Analysis: Arctic regional analysis, barotropic streamfunctions, sea-ice production and melting and sea-surface height histograms. More updates can be found in the v1.8.0 Release Notes.
MOAB: …
NCO: Compression support improved, ncremap supports EAMxx and new vertical interpolation methods, NCZarr support added, see the release notes for versions 5.1.1-5.1.3
xcdat: There have been several releases since the previous E3SM-unified including v0.3.1, v0.3.2, v0.3.3, and most recently v0.4.0. All of these releases address various bug fixes for features such as spatial/temporal averaging and horizontal regridding. v0.4.0 introduces includes a feature update to support datasets that have N dimensions mapped to N coordinates to represent an axis.updates (e.g., E3SM native datasets). See the changelog for a complete list of updates.
zppy: … More updates can be found in the v2.2.0 Release Notes.
zstash: … More updates can be found in the v1.3.0 Release Notes.
Activation
As in previous versions, you can access the environment as usual by sourcing an activation script:
Acme1:
source /p/user_pub/e3sm_unified/envs/load_latest_e3sm_unified_acme1.sh
Andes:
source /gpfs/alpine/proj-shared/cli115/e3sm-unified/load_latest_e3sm_unified_andes.sh
Anvil:
source /lcrc/soft/climate/e3sm-unified/load_latest_e3sm_unified_anvil.sh
Chrysalis:
source /lcrc/soft/climate/e3sm-unified/load_latest_e3sm_unified_chrysalis.sh
Compy:
source /share/apps/E3SM/conda_envs/load_latest_e3sm_unified_compy.sh
Cori-Haswell:
source /global/common/software/e3sm/anaconda_envs/load_latest_e3sm_unified_cori-haswell.sh
Perlmutter (CPU nodes):
source /global/common/software/e3sm/anaconda_envs/load_latest_e3sm_unified_pm-cpu.sh
After 5 weeks of testing, the new version has been deployed on most machines: Acme1, Andes, Anvil, Chrysalis, Compy, Cori-Haswell, and Perlmutter. We have dropped support for Badger, Cooley and Cori-KNL in this release.
On 5 machines (Anvil, Chrysalis, Compy, Cori-Haswell and Perlmutter) there are 5 important packages -- ESMF, MOAB, NCO, TempestExtremes and TempestRemap -- that have been built with Spack with system compilers and MPI libraries (matching the modules used for E3SM whenever possible). 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.
The ILAMB package is also available only on compute nodes because it, too, is built with the system MPI.
Next version
Testing of the next version (1.9.0) is planned to begin in early June 2023 and deployment is expected in early July. To request packages and versions to include, make a comment on Next Version.
As always, please email me if there are any questions, or post an issue at https://github.com/E3SM-Project/e3sm-unified/issues.
Cheers,
Xylar and the Infrastructure Team
