Instructions on how to build and run the stand alone ca_global code on hera
1.  Copy enitre directory strucure
  cd /scratch2/BMC/gsienkf/Philip.Pegion
  cp -r NEMSfv3gfs_develop  <your path>

2. Optional Compile full model: (I alredy built is, so you should not have to)
    cd <your path>/tests/
    ./compile.sh $PWD/../FV3 hera.intel '32BIT=Y HYDRO=N' 1 NO NO

4.  compile standalone model  
    cd ../stochastic_physics
   # my loaded modules:
    1) intel/18.0.5.274   3) netcdf/4.7.0   5) contrib       7) anaconda/latest
    2) impi/2018.0.4      4) hdf5/1.10.5    6) grads/2.2.1


    compile_standalone_ca OR compile_standalone

5.  There is an input.nml which is currently set to run at C96, and the INPUT directory points to
    C96 grid files. If you want to run at C384, you will need to rm INPUT and link in the C384 
    directory (ln -sf INPUT_C384 INPUT) and make npx and npy 385 in input.nml

5.  get an interactive session
 
    salloc --x11=first -q debug -t 0:30:00 --nodes=1 -A <your account> -n 6

6.  run job
    srun standalone_ca OR standalone_stochy

7.  post-process job to 360x180 grid (script is on hera in ~Philip.Pegion)
    run_fregrid.sh (OR run_fregrid_c384.sh)

    output file is ca_out.nc
