=====================10/11/2022=============================
we have modified the modulefiles of two installations on Hera to get multi-versions of netcdf working fine.
---------------changes---------------
comment out the automatic load of netcdf default modules in the modulefiles of parallel version of wgrib2/2.0.8 (default version), ncio/1.1.0 (default version), and nccmp/1.8.9.0. comment out of automatic load of hdf5 in netcdf.
---------------Impacts---------------
No more automatic loading of netcdf when loading these libs. Users have to load the specific versions of netcdf lib (or hdf5) before loading these libs.
---------------background---------------
Background: netcdf and hdf5 libs have stopped on netcdf/4.7.4 and hdf5/1.0.6 for a long time. Now some developers are leading the tests of netcdf/4.9.0 and hdf5/1.12.2. Major users are still using old ones. Automatic loadings in the modulefiles only load defaults.
Please do the corresponding loadings in your code before using these two libs.
=====================Feb 3, 2022==============================
We are going to be doing a major library clean up on HERA so please read the following
- We will be deleting the NCEPLIBS directory under nwprod. This is an old unsupported installation and all modeling systems should move to hpc-stack. To use hpc-stack please see the instructions at
https://github.com/NOAA-EMC/hpc-stack/wiki/Official-Installations
-
We are also fading support for Intel 18.0.1 to make room for newer compiler versions, so please upgrade your builds to the newer compilers
-
Under hpc-stack we will be removing older versions of UPP library and keeping just the last 3. The ufs-weather-model since November has moved to UPP being a submodule so if your code base is later than that you do not have to worry. If you need to have older library versions please let the library team know
ALL OF THESE ACTIONS WILL HAPPEN ON MARCH 31st. PLEASE TAKE ANY CORRECTIVE ACTiON BEFORE THAT

===================================Dec 2021================================
The following intermediate ESMF libraries are planned to be gradually removed on the UFS tie-1 platforms.
8_1_0_beta_snapshot_27 8_1_0_beta_snapshot_36 8_1_0_beta_snapshot_47
8_1_0_beta_snapshot_27-debug 8_1_0_beta_snapshot_36-debug 8_1_0_beta_snapshot_47-debug
For developers who are using those ESMF versions, please merge your branches to use a later version of ESMF library that are available. Currently the develop ufs-weather-model branch is using the ESMF public release 8_2_0. Please create an issue in the ufs-weather-model repository if you have any concerns/questions.
