Both 4.9.0 and 4.9.1 are backward compatible. So both should work.

But yesterday Hang mentioned some problem with running the UFS and netcdf-c-4.9.0. I don't have the details.

Certainly we should use 4.9.1, it has bugfixes in the quantize/compress code, and we want those.

@junwang-noaa According to the discussion with @edwardhartnett, the release of netcdf-c-4.9.1 may wait for months. So, we have installed the hdf5/1.14.0 with netcdf-c-4.9.0 series (netcdf-fortran4.6.0; netcdf-cxx 4.3.1) and associated mapl etc libs on Hera and Acorn.
Hera location (hpc-stack loading) :
/scratch2/NCEPDEV/nwprod/hpc-stack/libs/hpc-stack-gfsv16

Acorn location:
module use /lfs/h1/emc/nceplibs/noscrub/Hang.Lei/works/libs/modulefiles/mpi/intel/19.1.3.304/cray-mpich/8.1.9

@Hang-Lei-NOAA Thank you for installing the library on hera/acorn. Please let us know when the library is available on wcoss2.
@DusanJovic-NOAA FYI.

I have updated the installation of hdf5 /1.14.0 with NETCDF/4.9.1 on hera installation.

@hang does the netcdf-c-4.9.1 suffer the same problems with UFS as 4.9.0? Or are they fixed?

We really shouldn't need 4.9.0 and 4.9.1, everyone should just use 4.9.1. But is that OK with @junwang-noaa ?

@edwardhartnett The previous reported tests on Hera seems fine. But I am working on Acorn to solve a series of associated possible issues with the UFS failure that Pan Li reported. My first fix is to get the esmf 8.4.0 external working, then get the netcdf updated, then to fix the mapl/2.34.0 installation. Then I will repeat Pan LI's UFS tests.

@edwardhartnett Just to confirm that we are going to use 4.9.1? Also may I ask what is the problem in UFS with 4.9.0? If netcdf 4.9.1 is working with current UFS test, we can update 4.9.1 and start to update the code to get the new features. My understanding is that netcdf 4.9.0 is backward compatible.
