Modules required

  1. lang/Perl/5.28.1-GCCcore-6.3.0
  2. data/netCDF-WRF/C-4.6.2_CXX-4.3.0_F-4.4.2_p-1.9.0-intel-2018.5.274
  3. toolchain/intel/2018.5.274
  4. devel/CMake/3.12.1-intel-2018.5.274
  5. data/XML-LibXML/2.0206-GCCcore-6.3.0

Preparation

The required modules have taken care of several of the setup that are unique to certain climate models, such as CESM, where it expects libraries to be placed.  For example, the netCDF-WRF module takes care the fact that CESM 1.x expects netCDF and the different variants of netCDF to all be within the same directory tree.  As our modules do not typically do this, and these days netCDF comes as distinct libraries, a module was created that does this for you.  As the module name suggests, it also works in the case you wish to build your own copy of WRF instead of using the provided module of WRF.


As the dependencies are all available on Mana already, you just need to download and unpack the CESM source code into your user home on Mana following the download instructions for CESM https://www.cesm.ucar.edu/models/current.html .


Configuration Files

Once the source is acquired, changes need to be made to the config_machines.xml and a mkbatch, and env_mach_specific need to be made per new machine.   These files would be added and modified in "scripts/ccsm_utils/Machines/"

Below you can find the changes and contents of the files that need to be created.

As Mana has two different Infiniband networks (QDR and HDR), two different machine entries are created.  This also means that env_mach_specific and mkbatch  files will also come in duplicate with slightly different file names and the only content change is the  selection of network to use for MPI.

env_mach_specific files

A files for the uhhpc_qdr and the uhhpc_hdr machines needs to be made to define the build environment.  These two files should be identical as building for the QDR or the HDR network are identical on Mana.

Build  & Run

Once the above files are made and added to the  "/scripts/ccsm_utils/Machines/" of the CESM directory, we should now be able to build and then even run our model.
