[Ncep.list.fv3-announce] Using FMS as a library in UFS

[Jun Wang - NOAA Federal]

Dear all,

I would like to let you know about a recent change (PR#534
<https://github.com/ufs-community/ufs-weather-model/pull/534>) in the
ufs-weather-model repository. The FMS submodule has been moved out of the
ufs-weather-model repository, it is built as a library under hpc-stack and
used as a prebuilt library in ufs-weather-model build system. This code
update significantly reduced the compile time in many UFS applications.

Developers are encouraged to merge their branches to the top develop branch
to take advantage of this new feature.  Currently the FMS library is
available in hpc-stack on the tier-1 UFS support platforms
<https://github.com/ufs-community/ufs-weather-model/wiki/Regression-Test-Policy-for-Weather-Model-Platforms-and-Compilers>
and tier -2 NCAR cheyenne system. Developers using these systems should be
able to build the model after the merge without additional code changes.
Developers using other platforms will need to build the FMS library under
hpc-stack before building the model executable. Thank you!

Have a great weekend!

Jun
